How to call VS Code Editor from terminal / command line - command-line

The question says it all.
How can I open VS Code editor from
windows cmd
linux and mac terminal
e.g. for notepad++ I write
> start notepad++ test.txt
By the way, the editor is awesome (cross-platform)! Thank you Nadella!
You can download it from microsoft

To open a file or directory use the command:
code /path/to/file/or/directory/you/want/to/open
For macOS users, it needs to be installed manually:
Launch VS Code.
Command + Shift + P to open the Command Palette.
Type shell command, to find the Shell Command: Install 'code' command in PATH and select to install it.
Restart your terminal.

Per the docs:
Mac OS X
Download Visual Studio Code for Mac OS X.
Double-click on VSCode-osx.zip to expand the contents.
Drag Visual Studio Code.app to the Applications folder, making it available in the Launchpad.
Add VS Code to your Dock by right-clicking on the icon and choosing Options, Keep in Dock.
Tip: If you want to run VS Code from the terminal, append the following to your ~/.bash_profile file (~/.zshrc in case you use zsh).
code () { VSCODE_CWD="$PWD" open -n -b "com.microsoft.VSCode" --args $* ;}
Now, you can simply type code . in any folder to start editing files
in that folder.
Tip: You can also add it to VS Code Insiders build by changing "com.microsoft.VSCodeInsiders". Also if you don't to type the whole word code, just change it to c.
Linux
Download Visual Studio Code for Linux.
Make a new folder and extract VSCode-linux-x64.zip inside that folder.
Double click on Code to run Visual Studio Code.
Tip: If you want to run VS Code from the terminal, create the following link substituting /path/to/vscode/Code with the absolute
path to the Code executable
sudo ln -s /path/to/vscode/Code /usr/local/bin/code
Now, you can simply type code . in any folder to start editing files
in that folder.

VS Code is a must have code editor for 2018
For Windows 10 users a lot is possible, the same way the Mac OS users type code . .
Look for you VS Code \bin folder path e.g C:\Program Files\Microsoft VS Code\bin . The bin folder includes a file called code.cmd .
If you are not sure about what is your path, type where code.cmd, and then, copy it without the \code.cmd after the ...\bin.
Follow the steps below and be proud of the OS you use.
Search for "Advanced System Setting" from Start.
Click on Environment Variables.
On System Variables choose "path" from Variable tab and click on Edit.
Click on New on the right side of the popup window.
Copy your path from the Explorer's breadcrumb path and paste it into the new opened path in step 4, example:- C:\Program Files\Microsoft VS Code\bin.
Click Ok on all the open windows to confirm changes and restart your cmd .
Go to your cmd and navigate to you working directory on server and type code . .
C:>cd wamp64\www\react-app> code . to open with VS Code on Windows.
Visual Studio Code also includes a command prompt (terminal) window and you can open one or more of them with:
Ctrl + ` on your keyboard.
Hope this helps some one like it did to many of us.

You can also run VS Code from the terminal by typing code after adding it to the path:
Launch VS Code.
Open the Command Palette (⇧⌘P) and type shell command to find the Shell Command: Install code command in PATH command.
Mac shell commands
Restart the terminal for the new $PATH value to take effect. You'll be able to type code . in any folder to start editing files in that folder.

For VS Code Insiders Windows users (vs code doc):
Add the directory "C:\Program Files (x86)\Microsoft VS Code Insiders\bin"
at %PATH% environmental variable.
then go to the folder that you want to open with vs code and type:
code-insders .

Sometimes setting path from VS Code command palette does not work
Instead manually add your VS Code to your path:
Run in terminal
sudo nano /etc/paths
Go to the bottom of the file, and enter the path you wish to add
Hit control-x to quit. Enter “Y” to save the modified buffer.
Restart your terminal and to test echo $PATH. You should something similar
~ echo $PATH /Users/shashank/.nvm/versions/node/v8.9.2/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Applications/Visual Studio Code.app/Contents/Resources/app/bin
Next time, you navigate to your project folder from terminal
Enter:
code .
or
code /path/to/project
Source

In the case of Linux and Mac, you want to navigate to the directory that you extracted the VSCode files using the 'cd' command. For example:
cd ~/Downloads/VSCode
Then you start the application by running..
./Code
'Code' being the name of the executable.
If you have root access on the machine, you can configure the system to allow you to start VSCode from anywhere by linking it to /usr/bin, where links to executables are often stored.
sudo ln -s /path/to/VSCode/folder/Code /usr/bin/Code
You can now launch VSCode from anywhere by typing:
Code

For command line heads you can also run
sudo ln -s "/Applications/Visual Studio Code.app/Contents/Resources/app/bin/code" /usr/local/bin/code
this will do the exact same thing as the Shell Command: Install 'code' command in PATH command feature in VSCode.

When installing on Windows, you will be prompted to add VS Code to your PATH.
I was trying to figure out how to open files with VS Code from the command line and I already had the capability - I just forgot I had already added it. You might already have it installed - check by navigating to a folder you want to open and running the command code . to open that folder.

In linux if you use code . it will open VS Code in the folder the terminal was in.
Using code . Filename.cs it will open in folder and open said file.

For linux Debian the below can be done
$ export PATH=$PATH:/usr/share/code
Then run it
$ code
$ code file.py
$ code workingdir

Open command line and type:
cd your_folder_path
code.cmd .
or
code.cmd your_folder_path
It will open your folder in Visual Studio Code.
Make Sure, you are inside the correct folder after executing "cd your_folder_path" command.

On Windows you can add the following path to the system environment variables.
C:\Users\username\AppData\Local\Programs\Microsoft VS Code\bin

This works for Windows:
CMD> start vscode://file/o:/git/libzmq/builds/msvc/vs2017/libzmq.sln
But if the filepath has spaces, normally one would add double quotes around it, like this:
CMD> start "vscode://file/o:/git/lib zmq/builds/msvc/vs2017/libzmq.sln"
But this messes up with start, which can take a double-quoted title, so it will create a window with this name as the title and not open the project.
CMD> start "title" "vscode://file/o:/git/lib zmq/builds/msvc/vs2017/libzmq.sln"

typing "code" in dos command prompt worked for me

On Ubuntu the flatpak version seemed broken. I uninstalled it and downloaded the deb package right from Microsoft.

I use the following command to load a project quickly (in linux)
cd into the project cd /project
run command code pwd
similar steps can be used in other Os too.

In linux terminal you can just type:
$ code run

Windows:
Add code CLI path in a system environment variable.
in windows default code cli path is (username is you pc username)C:\Users\username\AppData\Local\Programs\Microsoft VS Code\bin
Then you can check it like this by taking your project folder and open new cmd and type code .

Step 1: create a .bat file with the name you want e.g vscode.bat
Step 2: Write your path to Visual Studio Code
Step 3: Save it in C:\Windows\System32 directory
**
C:
cd Users\Bino\AppData\Local\Programs\Microsoft VS Code
Code.exe**
Step 4: You can call visual studio code from any where by typing "vscode" which is the name of your bat file

This will work. This is your directory name "Directory_Name"
sudo code --user-data-dir="Directory_Name"

Other easyway to do it on mac is :go to Command Palette[ Shift ⇧+ Command (⌘)+P] and type :Shell Command: Install 'code' command in PATH
once installed: Shell command 'code' successfully installed in PATH.
Then you can use code from the terminal as well.

If you install VS CODE using snap. You will need to add /snap/bin in your PATH environment variable.
so - open your .bashrc or .zshrc
and add :/snap/bin in your PATH environment variable
reload terminal,
and than code comand will start it

A simple way is to go to your Project where you want to open it and type
code.cmd D:\PathTo\yourProject\MyProject
That's it. It will open your project in Visual Studio Code.

Delete old virtual environment and create a fresh virtual environment.

In a way I am reticent to add to the long list of answers. However, I searched this page for the word "portable" and came up empty. (And I did a full Stack Overflow search and also found nothing.) So I want to add this very specific answer for potential future searchers.
This answer is for if you installed VS Code in Portable Mode on Windows 10.
"Portable Mode" refers to what is described on the official VS Code web pages, which as of 21 January 2021 are found here: https://code.visualstudio.com. It does not mean the Visual Studio Code Portable project started/run by Gareth Flowers, or any similar project. (I am not saying anything bad about this or other projects - I have neither used nor evaluated.) If you are using one of those projects, you need to check with that project documentation/community - although this might work.
"Installing" VS Code in Portable Mode is downloading a .zip archive and extracting it locally wherever you want your VS Code "installation" to live. There is no actual installation or setup that is run, so there is no automatic adding of the code command to your PATH.
Answer
After extracting the Portable Mode VS Code files to the location of your choice, there should be a bin folder in that location. Copy the full path of that bin folder and add it to your System or User (your choice) PATH variable.
You should then be able to use the code command from PowerShell or CMD.

In linux you need to check first what is the name you your vscode binary file
When you get the binary file name check where it is by using this command :
whereis your_file_name
Go to the / (root) and go to bin and rename file with any name what you want to call it.
To rename : mv your_file_name your_changed_name
Now you can access vscode from any where in terminal
This works on Debian based Os definitely

Visual Studio Code - "Shell Command: Install 'code' command in PATH command."

Consider:
I just started with Angular. I installed angular/cli and added a project.
Now I want to use Visual Studio Code.
I open the Command Palette (Ctrl + Shift + P) and type 'shell command' to find the shell command: Install 'code' command in PATH command.
But I get this message
"No commands matching"
Why does it not exist?
With Windows it is installed by default so you don't need to add path. Just run " code . " in cmd and it will work fine
If in Visual Studio Code doesn't appear that option and the installation didn't add to the path directly, you can add the Visual Studio Code bin folder manually to the path and it starts to work.
Go to the Enviroment Variables and edit the Path user variable.
Inside of it, add a new variable with the current bin path of your Visual Studio Code installation.
Mine, for example, is "C:\Users\Inazio\AppData\Local\Programs\Microsoft VS Code\bin"
After that, you can start to use the code command in your OS
I had this same problem. Long story short, I uninstalled VS Code, re-downloaded the installer package and ran that. Sure enough, one of the install screens has a checkbox option to add to the PATH variable and this option is unchecked by default.
Checked the box, finished the install, works fine.
Of course it's perfectly valid to modify the PATH variable after install, but I think it's important to clarify that (at least version 1.23.0) does not update PATH by default. Most of the threads I looked at says it does.
I fixed this just adding "C:\Users\myUser\AppData\Local\Programs\Microsoft VS Code\Code.exe" (where myUser is your windows user) without "" to system path.
same effect than " Shell Command: Install ‘code’ command in PATH ".
This works for me
For Windows users
Open Environment Variables
System > Advance system settings > Advanced tab > environment variables on system variables click on Path and click Edit and add new Path named
"C:\Users\Your-Username\AppData\Local\Programs\Microsoft VS Code\bin"
For window users follow steps below and add new Path, after doing so restart your terminal you will get code command on your terminal
If you already have Visual Code into Windows path and in a terminal you put "code ." and Visual Code starts, what happens is that the command "code" is not linked to the path in wsl2.
All you have to do is run the following command changing your user:
sudo ln -s /mnt/c/Users/CHANGE_USER/AppData/Local/Programs/Microsoft
VS\ Code/bin/code /usr/bin/code
This works on Ubuntu and Debian.
it is already installed on Windows. You just have to make cmd path where the project created (e.g C:\WINDOWS\system32> cd C:\WINDOWS\system32\hello-world), then run the the comamnd "code ." like this (C:\Windows\System32\hello-world>code .)
I got this from VS Code documentation
the path has been set automatically when installing VS.But i noticed a difference between "code." and "code ." Can you see the difference? The second has space in between the code and the dot. Try that.
I was having the same exact problem and when i checked my PATH variable it said that the path was something\something\Microsoft VS Code . then i remembered my folder's name was Visual Studio Code.After I renamed it back everything works.
Go to Extensions and install Shell. On newer versions you can just type in Code . in CMD and it will pop-up.
Just open your command prompt and type:
cd hello-world
hello-world is the project name don't forget to change it then click (enter) and type
code .
Visual Code already have internal terminal window
Use the Ctrl+` keyboard shortcut with the backtick character.
Its supports all Ubuntu terminal commands

Set global $PATH environment variable in VS Code

I'm defining a custom $PATH environment variable in my ~/.bash_profile (on a Mac), like so:
PATH="$HOME/.cargo/bin:$PATH:$HOME/bin"
However, VS Code of course does not run my .bash_profile, so it does not have my custom paths. In fact, if I Toggle Developer Tools and check process.env.PATH, it doesn't even seem to have /usr/local/bin.
How do I globally set the $PATH environment variable in VS Code?
(I want to set it globally, not per project or per task, since I'm maintaining a lot of small packages.)
If you only need the $PATH to be set in the integrated terminal, you can use VS Code's terminal.integrated.env.<platform> variable (added in version 1.15). Press Cmd+Shift+P (or Ctrl+Shift+P) and search for "Preferences: Open Settings (JSON)". Then add the following entry to the settings file:
"terminal.integrated.env.osx": {
"PATH": "...:/usr/bin:/bin:..."
}
(Replace .osx with .linux or .windows as needed.)
To see your system's $PATH, type echo "$PATH" in Terminal.app, and copy and paste it into the settings snippet above.
As for having the $PATH available everwhere in VS Code, so that it will
be used by extensions that call binaries, the only workaround I've found so far is this:
Configure your shell (bash by default) to have the $PATH you want. For example, my ~/.bash_profile has the following line:
PATH="$PATH:$HOME/bin"
In VS Code, press ⇧⌘P and type install 'code' command if you haven't done so before.
Quit VS Code.
Launch VS Code not by clicking the icon in the dock or in Launchpad, but by opening Terminal.app and typing code. Your newly set path will be active in VS Code until you quit it.
If VS Code restarts, for example due to an upgrade, the $PATH will reset to the system default. In that case, quit VS Code and re-launch it by typing code.
Update: VS Code on Mac and Linux now apparently tries to automatically resolve the shell environment when it is started by clicking the icon (rather than via code). It does this by temporarily starting a shell and reading the environment variables. I haven't tested this though.
In:
> Preferences: Open Settings (JSON)
add to the JSON file:
"terminal.integrated.env.windows": {
"PATH": "${env:PATH}"
},
-> terminal.integrated.env should end with .osx, .linux or .windows depending on your OS.
In order to check if it works execute in your VS Code Terminal:
# For PowerShell
echo $env:PATH
# For bash
echo "$PATH"
I am using vscode on macos for C/C++ development in conjunction with CMake.
The vscode extension CMake Tools allows to manipulate environment variables via the configuration properties cmake.configureEnvironment, cmake.buildEnvironment and cmake.environment (acting respectively on the CMake configuration phase, the build phase and both - see docs).
Then you can extend your system PATH with custom paths by adding the following snippet to your user or project settings.json:
"cmake.environment": {
"PATH": "~/.myTool/bin:${env:PATH}"
},
Visual Studio Code is the problem.
No matter how you set your PATH variable in the shell, there are cases where Visual Studio Code will not inherit your PATH setting. If you're using an application launcher like LaunchBar to start Visual Studio Code, your PATH variable will not be inherited.
Here is a system-wide fix:
In the /etc/paths.d directory, create a file with your Unix username. In that file, place the additional paths that Visual Studio Code needs to work. In my case, this is the contents of my /etc/paths.d file:
/usr/ucb
/opt/local/bin
/opt/local/sbin
~/go/bin
Note: Your /etc/paths.d file will be processed system-wide. Since most systems are single-user, this shouldn't be a problem for most developers.
Since this is the top Google search result for variants of "VS Code path", I will add my answer here.
I'm running Linux and my problem was that VS Code couldn't find some executable needed to build my project. I was running VS Code from the quick launcher (ALT+F2), and not from a Terminal. I tried modifying the PATH variable in many different places, but I couldn't seem to get it right.
In the end, placing the right PATH inside of ~/.zshenv is what worked. It's because .zshenv is the only file that gets sourced for non-interactive shell command execution like from inside of VS Code (more detailed explanation here https://unix.stackexchange.com/questions/71253/what-should-shouldnt-go-in-zshenv-zshrc-zlogin-zprofile-zlogout )
This was even easier to fix than the above answers suggested.
Open VSCode Settings (Ctrl + ,) and search for terminal.defaultProfile.
I updated my Terminal > Integrated > Default Profile: Windows.
It was set to null by default. As soon as I changed it to PowerShell and restarted the terminal, it picked up my system's path variables!
What did the trick in my case (Linux Mint 19.3 Cinnamon, VS code installed via snap) was to put my appended PATH in ~/.profile . Since this file is read at the beginning of a user session, don't forget to logout/login or reboot after editing this file.
I'm working with ubuntu 18.04. I had a similar problem, my enviroment variables were defined and the terminal knows the $PATH but when I tried to debug with golang, go libraries were not found in $PATH variable.
So, to solve it I uninstall the default version from ubuntu software and install manually using the following instructions:
https://code.visualstudio.com/docs/setup/linux
It works for me.
As of VS Code v1.63.2, you can proceed with Ctrl + Shift + P and then type Open Settings (JSON), and simply add the following line.
"terminal.integrated.inheritEnv": true
In my case the code was already there, but set to false. After changing it, everything was fine.
Getting Code to load your existing ~/.bash_profile would be best. I think the docs here are the relevant reference:
https://code.visualstudio.com/docs/editor/integrated-terminal#_linux-os-x
Typically $SHELL is your primary shell on Unix-like systems so you
probably won't want to change the shell. You can pass arguments to the
shell when it is launched.
For example, to enable running bash as a login shell (which runs
.bash_profile), pass in the -l argument (with double quotes):
// Linux "terminal.integrated.shellArgs.linux": ["-l"]
// OS X "terminal.integrated.shellArgs.osx": ["-l"]
Although, it looks like that setting is the default on my current VS Code (OS X) setup. Integrated terminal is running my ~/.bash_profile without any changes to the configuration. Perhaps try adding echo Executing .bash_profile... to test if it's running when a new terminal is opened in Code.
Add the following to your ~/.bash_profile:
launchctl setenv PATH $HOME/.cargo/bin:$PATH:$HOME/bin
Or run a Bash script when needed, e.g.:
#!/bin/bash
set -Eeuxo pipefail
proj_path=$( cd $( dirname ${BASH_SOURCE[0]} ) && pwd )
launchctl setenv PATH $proj_path/bin:${PATH:-}
For me it's resolved by editing the .desktop file.
Originally I have
Exec=/usr/bin/code-oss --unity-launch %F
. Just changed to
Exec=zsh -c "source ~/.zshrc && /usr/bin/code-oss --unity-launch %F"
since I use zsh, instead of bash. But if you have the same problem with bash, simply replace zsh with bash. And shortcuts from your desktop environment should be fixed.

How to open folders in VSCode via Terminal in a fresh state?

It appears that VSCode always opens a folder in with the last UI state it had.
I'm looking for something like Sublime's remember_open_files: false, or in other words, I would like VSCode to open up with a clean UI state regardless of what state the UI was in the last time the folder was open.
What's happening now:
cd my-project-folder/
code .
# VSCode opens folder with saved UI state
What I want:
cd my-project-folder/
code .
# VSCode opens folder with fresh UI state
I tried to do it through command line using the command
code -n .
which should have opened VS code in current folder with a new session but it does not seem to work at all. I believe that code . seems to ignore the -n new session option and restores the previous session for the folder. So this feature is probably not implemented in VS code.
(Refer here for the commandline options for VS code.)
this is the command that works for me on windows
code -r .
From inside VS Code built-in terminal, cd into your project folder/directory and enter command:
code -a .
Note period at end.
This will open your current directory/project folder without opening a new window.
Part of the answer on this thread worked for me. Basically, make sure VSC is in the Applications folder. Then open the Command Palette (F1 or ⇧⌘P on Mac) and type shell command to find the Shell Command: Install 'code' command in PATH command.
Restart Visual Studio Code if it's open. In terminal, navigate to the folder you want to open in VSC, and type code .. Hopefully it should work for you.
If you are using a Mac, you need to first install the VSCode command amongst the shell command list.
Do this:
Open VSCode
press CMD + SHIFT + P
type shell command
select Install code command in path
navigate to any project from the terminal and type code .
code . opens VS Code at the current terminal folder
If you are using VS Code [Version: 1.50.0] then open your command prompt and go to your project's directory and just run the command:
code -a .
i.e. [Also can see the photo]
[1]: https://i.stack.imgur.com/sMmkH.png
$ code . --user-data-dir=.
This will open Visual Studio Code in current working directory. I use Bash with Ubuntu 16.04LTS.
I am using VS Code Version 1.24.1 (As of the time of original posting).
If you want to open a folder through the terminal, you can execute the command:
code -n name_of_your_folder/
or
code -n path_to your_folder/
Same thing goes for a file, and these open VS Code in a new window.
Also, note that you should have VS Code installed.
You're welcome!
I checked through all of the settings available in the VSCode preferences for me, and I don't think there is a way to do this.
There are some settings related to what VSCode window instance that folders will open into, but nothing that seems similar to Sublime Text's remember_open_files setting.
The closest thing I found was running code --user-data-dir . (feel free to replace . with some other directory so you don't pollute your current working directory) from the terminal to specify that VSCode shouldn't remember ANY previous settings, but this seems like overkill for what you're trying to accomplish (as VSCode will literally run as if it's the first time it's being run after a fresh install).
EDIT: I just discovered a View: Close All Editors command in the command palette (CMD + SHIFT + P). The keyboard shortcut for OSX is CMD + K, CMD + W, and this will close all the files you have opened!
I have the same problem on Mac.
I solved it in the following steps:
I opened the "Command Pallete" on the VSCode. This can be done by CMD + SHIFT + P
Type "shell"
Click on 'Install code command in path'
Give an administrator password
You will get a message that it has been installed
Now run "code ."
NB: Make sure you already cd into the folder you want to open before you run code .
If you want to open folder with vscode, you just go to folder ( you can user terminal or file explorer) with terminal, and do "code ."
To get the right folder in VS Code v 1.50.1 Terminal I tried a lot of options which didn't work for me. At the end I found very easy solution. I went to File->Open Workspace and found that my Workspace had the wrong folders inside it, which I simply deleted (from Workspace only!). Then I opened the folder I needed in my Workspace, opened Terminal->New Terminal, and everything worked perfectly well. Please let me know if this will work for someone else.
This command works to open a specific folder in VS code using terminal
code -r Documents/VS/C++/
here -r switch is used to open a file or a folder in an already opened VS code window
and then you specify the path of the file or folder you want to open
if you want to open it in a new window use -n switch instead of -r
This works for me with VSCode on Linux:
cd path/to/project
codium .
I tried every mentioned answers, what's work from me is this:-
I created a shell script to open folders.
$ sudo nano /usr/local/sbin/code2
/usr/bin/code-oss -n --user-data-dir '/home/myusername/.config/Code - OSS2/' -a $#
$ sudo chmod +x /usr/local/sbin/code2
You can remove --user-data-dir '/home/myusername/.config/Code - OSS2/' from the script if you want to use default code-oss config folder.
When I want to open a folder, I use the command like this :-
$ code2 .
I add this command code2 to open with option thunar to open folders directly from files manger.
Go to the directory in the command pallet on your computer the navigate to the the specific folder using cd
the type code . and that will open the folder and the files in it inside vs code. works like a charm.
If Visual Studio Code is installed using flatpak then a bash alias can help launch the application from the terminal.
alias code="flatpak run com.visualstudio.code"
I did it a simpler way just by three steps. I am currently in a project folder and want to open another folder in vs code using the cli or terminal. What I first did is navigated in the folder which I wanna open in vs code inside the terminal. Once I m inside that particular directory or folder I simply typed the command :
start code .
This will open that directory or folder in a new vs code window.
The complete process is :
open the terminal is vs code
navigate to the folder u want to open
once u r inside that particular folder type the command :
start code .

How to open a file from the integrated terminal in Visual Studio Code?

Is there a way of opening a file from the terminal in Visual Studio Code that opens in the same vscode instance that runs the terminal? Similar to c9 tool in Cloud9.
I'm aware of the code tool, but when you run code something.php from the integrated terminal it opens a new vscode instance, which is not what I want...
You can use -r or --reuse-window command line option.
code -r something.php
just
code file_name
I tried it on Win10 and on Linux (Ubuntu)
I don't know what operating system you're using, but on MacOS you can just say open filename.ext in the integrated terminal, and it will open a new tab in the same VSCode instance, ready for you to edit.
If you are having command not found: code in macOS, use a full path to it.
/Applications/Visual\ Studio\ Code.app/Contents/Resources/app/bin/code -r [filename]
Open Visual Studio Code
Press CMD + SHIFT + P (this opens "Command Palette")
Type shell command
Select “Install code command in path”
Navigate to any project from the terminal, and type code .
If it didn't work, select “Uninstall code command from path” first, then reinstall it again.
I use code -r . to open the current directory in the main window.
You can use the code command from the CLI to open a file, but if you want it to open in the existing window, either use code -r <file> as mentioned in other answers (which does work for me on Ubuntu Linux), or, if -r does not work (under WSL?), make sure window.openFilesInNewWindow is either off or default in settings.json or the in VS Code settings UI, then use code <file>.
Many things can be found in open --help
A work around that worked for me on MacOS is:
open -a 'Visual Studio Code.app' something.php
in the version 1.31.0 that I have installed, on Windows 7, the only way I found to do this is to e.g. change the file associations in system so that .cproj and .cs files are opened by Visual Studio Code by default, and type "filename.cs" in Terminal to open file by that name in the same window... -r option is not working for the first call (opens a new window), but with each subsequent call that same window is correctly reused. ok can't get to open whole directories this way - it's a bit shoddy anyway. probably it would be more convenient to use an outside shell and work with "-r" option
VSCode 1.64 (Jan. 2022) comes with a new command:
Keyboard Navigable Links
Previously, link navigation in the terminal required the use of a mouse.
Now, links can be opened using only the keyboard via the following commands:
Terminal: Open Detected Link... to view all links (web, file, word)
Terminal: Open Last Web Link... ex: https://github.com/microsoft/vscode
Terminal: Open Last File Link... ex: /Users/user/repo/file.txt
Check if the last command Terminal: Open Last File Link... would help in your case.

How to open Visual Studio Code from the command line on linux?

I know I can use command "code" to open VS code or file, but I don't know what should I do to make it possible after I install VS code in Ubuntu.Thanks.
Launching from the Command Line
You can launch VS Code from the command line to quickly open a file, folder, or project. Typically, you open VS Code within the context of a folder. We find the best way to do this is to simply type:
code .
Tip: We have instructions for Mac users in our Setup topic that enable you to start VS Code from within a terminal. We add the VS Code executable to the PATH environment variable on Windows and Linux automatically during installation.
Sometimes you will want to open or create a file. If the specified files does not exist, VS Code will create them for you:
code index.html style.css readme.md
Tip: You can have as many file names as you want separated by spaces.

So, there are a couple of solutions for this.
I've linked a video that shows you how to add vscode to $PATH
(which didn't work for me because I couldn't find the "shell:install path" command)
I uninstalled the vscode from my ubuntu and re-installed using sudo snap install --classic code
(This method worked for me)
Tell me which one works for you... and if you have extensions installed to your vscode then i guess you ought to make a backup or something.
