I'm new to programming and using python. I am unable to use the terminal to use command-line work. I can run script, but nothing from the command line
I cannot even do print('hello'), though I can do that on idle
I have reviewed some tutorials, but they are of no help
If you're talking about VS Code built-in terminal (Ctrl+`), before execute print('hello') or some similar code, you should first start Python interective session by typing in python and hitting Enter.

Ideally, the integrated VS Code terminal, depending on the context, the type of the folder and the extension, executes some commands. For example, when opening a folder containing a Python virtual environment in VS code, the environment is recognized and activated (by the python extension) by default when opening a new integrated terminal instance (situation 1). This is done by running some command similar to source /path/to/venv/bin/activate.
Or, when using the ROS extension to debug nodes, selecting "Start Debugging (F5)" uses the launch.json file to start some nodes and finally starts debugging the desired code. To do so also, there is some command that is executed (also by he ROS extension, I assume) in the integrated terminal (situation 2) to start the debugging process. In case of debugging ROS nodes, the command usually looks something like /usr/bin/env /bin/sh /tmp/someFileName.
But, unfortunately, both of the above mentioned situations fail. I believe this happens because while the extension tries to run these two commands within their respective integrated terminals, the commands do not actually get executed in either situation. Instead, these commands are printed on the top of the terminal, but the state of the terminal is unchanged (as opposed to when the commands would have been executed, in which case depending on the commands some actions are performed). Here are two images to show what I mean. Top, situation 1 and bottom, situation 2.
The fact that these two commands are printed on top of the terminal as soon as the a new terminal instance is opened tells me that the extension tries to execute them, but they do not work for some unknown reasons.
Just to be clear, both of them are run in a seperate VC Code window, they have nothing to do with each other. When I manually run both the commands in their respective terminals I do get the desired results.
Now, I am unsure exactly how to name this issue. But I think this is surely an issue with the integrated terminal, and not a problem of the extensions. I am not sure how one could reproduce this problem.
I did a clean reinstall of VS code by deleting %APPDATA%\Code and %USERPROFILE%\.vscode. Because I am using this on WSL, there is only ~/.vscode-server on the ubuntu side. I manually uninstalled all extensions on WSL but did not delete this folder, in fear of breaking something. The problem still persisted. I have also created an issue on the VS Code GitHub page with nearly the same information.
I am unsure if this is a bug or is there something wrong with my settings. Does anyone know how I could fix this? For smaller use-cases I can still manually enter the command in the terminal. But I am trying to debug a ROS application with nearly 10 different terminals opening up and I cannot be manually entering the command each time to restart the process.
Please let me know if you need any more information. Many thanks in advance.
Edit: both edits to frame the question properly.
Although not related to WSL, I dug a little deeper today as to why in my case the extension commands were not being executed or were being chopped.
I'm an iTerm2 user. iTerm2 has something called Shell Integrations, which allow iTerm to behave differently under certain circumstances, for example, adding markers to each prompt or coloring output with certain text (e.g. WARNING or ERROR)
From time to time, I also use the VSCode Integrated Terminal, which recently added support for reporting whether the previous command errored out with an indicator on the gutter of the Integrated Terminal panel using the exit code.
iTerm can do something similar but the shell integrations mess up completely the VSCode functionality and therefore I changed my .bashrc file to detect if the terminal emulator was iTerm2 or not (which can be done with the it2check utility of iTerm2) so that it only sourced the shell integrations if I was using iTerm2.
The problem is that it2check "eats" some STDIN bytes using dd, specifically, until it finds an n so that it can obtain the name of the emulator. This of course chops the commands on the STDIN until the first n and makes VSCode Extension Terminal commands unusable
The workaround I came up with is to use the value of "$TERM_PROGRAM" as means to distinguish between the different programs. The only caveat is that the value won't be passed if you're inside of a tmux session or similar, but I can live with that.
In your case, I'd check for any process that is either not passing the STDIN to the WSL process or any dot files or shell profile scripts eating up the STDIN they receive.
I suspect that the real problem is that the local process doesn't relay the STDIN contents to the WSL and as a workaround you may try to create a VSCode Integrated Terminal profile that uses SSH to connect to the WSL host so that the STDIN is preserved
I am inputing commands into my CLI to run my source code yet it doesn't recognise these standard commands. I have updated my includepath, that became effective as I noticed the squiggles no longer appeared under the text in my source code, but I am unable to run my code from the command terminal for some reason. For some context, I am using C language. My question please is what could be the reason why linux os refuses to understand simple commands such as ' g++ --version'? Any help would be appreciated, thanks.
I'd find it convenient to be able to quickly recall past commands issued in the terminal. In Matlab one can simply select any number of those from the Command HIstory panel, and reissue them in the Terminal all at once:
In VS Code (on Windows), I know there is a command to pull up the log text file:
(Get-PSReadlineOption).HistorySavePath
But I find this extremely cumbersome as a solution to call up multiple lines at a time. Is there an VS Code addon that creates a Matlab-like Command History panel with timestamped commands (didn't find any searching myself)? Or is such feedback taken into consideration by Microsoft?
See v1.70 release notes:
Triggering the Terminal: Run Recent Command... will bring up a QuickPick panel of recent terminal commands in which you can search, fuzzy or not, through the recent commands.
There are some examples of commands for going to the next item in the list, for example.
See the supported shells and OS's mentioned below. I believe it is still accurate. Git Bash on Windows doesn't work with this new recent command functionality, but powershell does. Support for MacOS and linux is stronger: bash, powershell and zsh.
And see v1.69 release notes: run recent command:
Some other functionality of the command:
In the current session section, there is a clipboard icon in the right
of the Quick Pick that will open the command output in an editor. Alt
can be held to write the text to the terminal without running it. The
amount of history stored in the previous session section is determined
by the terminal.integrated.shellIntegration.history setting.
There is currently no keybinding assigned by default but it can be
hooked up to Ctrl+Space for example with the
following keybinding:
{
"key": "ctrl+space", // whatever keybinding you want
"command": "workbench.action.terminal.runRecentCommand",
"when": "terminalFocus"
}
This might help (coming to v1.64):
Terminal shell integration
The terminal now features experimental opt-in shell integration which
allows VS Code to gain insights on what is going on within the
terminal as it was previously a black box. When enabled using
"terminal.integrated.enableShellIntegration": true, arguments to run
a shell integration script will be injected into your terminal profile
if possible. The script itself mostly just injects invisible sequences
into your prompt, providing us with information like where the prompt,
command and command output is, what the current working directory
(cwd) is for each command and the exit code of each command.
Shell integration enables the following new features:
Run recent command: Since we know what commands are run, we have
exposed a command that allows you to view and run them again in a
quick pick.
Developer: Run Recent Command run this command from the Command Palette
The current shells supported are pwsh for Windows and pwsh, bash and
zsh for Linux and macOS.
from release notes: terminal shell integration
Although I switched to powerShell on W11 to test this feature - which should be supported - I can't get it to work just now. I wanted to see if you could pick multiple command entries in the QuickPick to run a series of them, but I doubt you can. But at least you get a nice list of recent commands.
I'm using Python 3.8 on VScode, but I can't seem to get the program to write anything in output, even with simple commands like: print("Hello world!"). It shows up in the terminal well enough, so the code shouldn't be the problem. Do i need to fix anything in the setting to make it show the output?
1: Picture of terminal:
Please could you check your user settings.json and workspace settings.json for the existence of a setting for terminal.integrated.shell.*.
I believe you may have changed the shell to use command prompt instead of powershell.
Also, please could you provide some screenshots of the terminal
And any errors logged in the console widows (go to Help->Toggle Developer Tools)
I wonder how to use the code command to open the VS Code with the integrated terminal launching within with some commands running that I pass directly to the integrated terminal.
Right now I need to do a couple of actions to get it done:
open VS Code via code .
manually open the built-in terminal and run a command like npm run start
Maybe it's possible to open VS Code like this: code . --exec 'npm run start', and it may open the editor and also run another command in the integrated terminal just after VS Code is ready for work.
I look through the documentation and I couldn't find anything useful for this case. Maybe I need to look for something like plugin or tricky bash/zsh script?
Reminder: it’s important to run these “passed” commands via CLI directly in the integrated (built-in) terminal of the newly opened VS Code instance. I know that it's possible to open the editor and then run commands, like code . && npm run start, but it will be just another command in sequence after code, it's not the same as running commands in integrated terminal.
Thanks.
