I follow tutorial on Postgres 9.2 on postgres official site. They tell about postgres command, createdb command and so on. But I don't have them! I installed postgres with sudo apt-get install postgres on Ubuntu 12.04. Instead, I have brand new psql command.
When you're lacking a command on Ubuntu and don't know what package to install, you can go to http://packages.ubuntu.com/ and type the command name in the Search the contents of packages section.
In the case of createdb, it comes with the postgresql-client-common for the soft link installed in /usr/bin/createdb, and postgresql-client-9.1 for the actual binary that gets installed in /usr/lib/postgresql/9.1/bin/createdb
You need both packages.
However, if you already have a working psql, it normally means that you already have them installed, because it comes in the same packages.

I am using the Fish shell (version 3.3.1) on MacOS. Every time I run a command it shows this error multiple times:
error: Unable to open universal variable file '/': Permission denied
The commands still run perfectly, but it's very annoying to see these errors. They are still on the screen even after a clear command.
Fish has a feature where it'll store so called "universal" variables to a file on disk, so they can easily be persisted and shared among open fishes.
This error:
error: Unable to open universal variable file '/': Permission denied
Shows that fish is trying to open the file at "/", the root of the filesystem. This points to a misconfiguration, because "/" isn't a file, by definition. It's a directory.
The file is supposed to be in the config directory, which is at:
$XDG_CONFIG_HOME/fish, if that variable is set
$HOME/.config/fish, if it isn't
I can't find the specific sequence to reproduce this, but it appears that $XDG_CONFIG_HOME or $HOME are set when fish is started (by its parent process, probably the terminal), and to non-functional values.
Was having this same issue after installing using brew install fish.
What finally worked was uninstalling fish.
brew uninstall fish
Then removing fish from my .config folder.
cd ~
rm -rf .config/fish
Then I just installed fish using the fish GUI installer.

Trying out Windows 10 for first time. Installed winget onto my powershell, and then used winget to install vscode: winget install vscode. When I install vscode on a Mac/Linux, I get a command-line tool code that I like to use to launch vscode from my PWD: code -n .
But being new to Powershell and winget, I have no idea how to determine exactly what/where/how things got installed. In summary:
Is there a command-line tool like code installed by winget?
If not, how else might I launch vscode with a window on my PWD?
OK, after rebooting code -n . works as expected.

I have WSL with a directory ~/library created within WSL. Then I ran VSCode and opened this folder directly from Windows Explorer, causing to open it as a "local Windows" folder instead of WSL. Adding to the offense, I created 2 folders from VSCode (let's say foo and bar) inside library.
The cost of doing this is that now I can't delete these folders, either from Windows Explorer or WSL (sudo rmdir foo or sudo rm -rf foo). In Windows and Ubuntu I'm getting access denied errors. I am both Windows admin and root user.
Would be any workaround for removing them?
Maybe a little too late but to remove folder in your wsl just open your wsl/ubuntu terminal. cd /to get to your root. ls to find where you created the folder, in my case it was in: home/user/projects folder, cd home/user/projects. Type this command: rm -r folder-name, then ls to verify that the folder has been remove.

I am using XMing to run Emacs from WSL, which is working quite well. My issue is when trying to share folders between Windows and WSL. I have tried the following:
Project located in the Windows file system, accessed via /mnt/ in WSL
Symlink (created in WSL bash) of project located in the Windows file system
Copy the project to the WSL file system
Out of the 3 listed options, only the last works with projectile (and likely other Emacs packages). But I need to be able to access/modify the files from Windows as well, so that is not a viable option.
Has anyone found a good solution for this?
I do it so (also to sync between Windows_laptop & Ubuntu_pc):
I have folder "workspace"
and symlinks to it: windows symlink under win and linux symlink under linux.
%USERPROFILE%\Cloud\workspace
for Win usage:
made windows symlink: %USERPROFILE%\workspace -> %USERPROFILE%\Cloud\workspace
for Ubuntu usage (WSL):
made linux symlink: ~/workspace -> /mnt/C/Users/USER/Cloud/workspace
May this help?
One of the advantages of WSL (windows subsystem for Linux) is that you can share files easily with your windows.
I have used the below codes with WSL Ubuntu (but this should work with other versions of Linux as well). Using /mnt will do all the magic.
Syntax:- cd /mnt/drive/Folder/Subfolder
Sample code:- cd /mnt/c/Users/Saswat

When you double click on a file opens a new window emacs. Tell me how to do to open in the same
I beg your pardon, Linux OS
I installed emacs23
Then i run the command:
emacs --daemon &&
emacsclien -c &&
emacsclien -c
And i have opened 2 windows instead of one
You don't provide enough information, such as what OS/windowing system you're using, but the answer involves using emacsclient. The wiki page has all the details of using emacsclient, though not how to set up your OS/windowing system to associate the file types with emacsclient (instead of emacs).
You have a single Emacs instance with two windows. You have two windows because you explicitly asked for them by passing the -c option to emacsclient.
