I'm trying to customize my integrated terminal shell prompt in vscode, and was successfully able to change the theme (so that I can see my current working directory and branch I'm on), however now I want to remove the first portion 'anhlucci#Anhs-MacBook-Pro'. How do I do that?
I use Ubuntu with bash, and I only add the following lines to the end of ~/.bashrc:
if [ "$TERM_PROGRAM" = "vscode" ]; then
PS1='\[\033[01;34m\]\w\[\033[00m\]\$ '
fi
I found that vscode sets TERM_PROGRAM environment variable, and then use it to modify PS1 only to vscode.
The command line prompt is not dictated by Visual Studio Code, but by bash. The prompt is dictated by the PS1 variable in bash. You can view it as follows:
echo "$PS1"
To give you an idea of how that works, this is how my prompt looks like:
[hongli#Leticia Projects]$
My $PS1 looks like this:
[\u#\h \W]\$
Things like \u and \h are formatters that are substituted with a specific value. \u is for the current username, \h is for the hostname.
I'm guessing your $PS1 contains something like \u#\h in the beginning. Remove that and reset the PS1 variable, for example like this:
PS1='[\W]\$ '
Finally, you need to persist this in your bash configuration file so that the next time you start your shell it will show that same prompt. The bash config file is typically ~/.bashrc or ~/.profile depending on the exact Linux distribution you use. Make sure you set $PS1 in there.

I'm just trying to change the terminal prompt in macOS Sierra. Nothing fancy, I just need to know the current path.
In my ~/.bash_profile I'm adding
export PS1="[\w] > "
I know that \w should be replaced by current full path but none of the escape characters seems to work on my Mac. I just get the same string without evaluating, so my prompt looks like
[\w] >
I've tried many different PS1 strings without luck. I also tried using .bashrc instead bash_profile.
Any ideas?
I suspect you're running a shell that doesn't understand the \w escape in the prompt string. If echo $0 returns something other than -bash, you have to use whatever that shell understands:
Zsh prompt expansion
PS1 in the POSIX shell
Having just installed VScode I have noticed as it uses Bash by default on OSX, with the shell's default prompt of bash-3.2$; consequently, I cannot see the current working directory. It means having to type 'pwd' and 'ls' quite frequently which is obvious quite tedious.
I have tried changing the default shell in the settings to
"terminal.integrated.shell.osx": "/Applications/Utilities/Terminal.app"
or
"terminal.integrated.shell.osx": "/Applications/iTerm.app"
This doesn't seem to work, have I made a mistake here?
I would also like to know if I am limited to bash, can I configure it to display the working directory instead of simply bash-3.2$ ?
See this screenshot of how the VSCode integrated terminal looks by default
Thanks in advance!
I use Ubuntu, and only add the following lines to the end of ~/.bashrc:
if [ "$TERM_PROGRAM" = "vscode" ]; then
PS1='\$ '
fi
Try it and let me know if it works on your OS.
You can set your prompt to contain the current working directory by defining PS1 as follows:
PS1="\w $"
The $ is just some visual sugar. There all manner of things you can have your prompt display. Put the definition in your ~/.bashrc or ~/.profile for it to be set when you login.
Check out the Controlling the Prompt section of the GNU Bash manual for details.
If you are not accustomed to editing your bash init files you can do it with Visual Studio Code by going to View->Command Palette and execute the following command (one-time only):
Install 'Code' command in path
Then open the integrated terminal and type the following:
code ~/.bashrc
Then add the PS1 definition to the bottom of that file.
I want to disable the Unix shell prompt character ($, #, %) which usually we see in terminal. Is there any command or setting which can do this? I am using Solaris OS.
By shell prompt character I mean:
>$
>#
You need to adjust your PS1 environment variable in your .profile file.
I guess you could set it to "" to have it empty.
ex:
export PS1=""
EDIT: it can also be in your .bashrc file, or any other shell you are using.
You can get fancy and put the host name in there. But basically you change the PS1 environment variable:
export PS1=hello
You can add this command in your ~/.bashrc file. Or other startup file, if you use another shell.
I suggest first check the man pages for the shell (whatever is yours? echo $SHELL) under shell variables.
There are four types of prompt strings(PS) PS1, PS2, PS3, PS4, for your problem PS1 adjustment is sufficient.
To check the current settings: echo $PS1
To change: PS1="" for the current session, to make it permanent export it in your ~/.bashrc or ~/.profile.
To make it permanent for the user: export PS1="whatever special characters you want"
for more special characters and examples you can visit here "http://linuxconfig.org/bash-prompt-basics"
I was editing .bash_profile and after I saved it ,terminal shows nothing.How can I reset it to previous mode.This is how it looks now.
I changed the value of PS1 variable.I don't have any knowledge about terminal.Please help.
The PS1 environment variable defines what the bash prompt looks like. The default varies among distros, but is generally something like this:
PS1='\h:\W \u\$ '
The bash manpage has an explanation of PS1 values under the heading "Prompting".
You can apply PS1 values to your current terminal session by pressing Control+C several times, then pasting in the line of code above and pressing return or enter. That should get your environment behaving normally long enough to edit your bash profile unless something else is wrong.
If something else is wrong with your profile, and bash is completely broken, you can temporarily use a different shell (one that doesn't care about your bash_profile) with the "New Command..." option in Terminal.app's file menu. When prompted for a command, enter /bin/zsh. You should then get a usable terminal window which you can use to edit or move your .bash_profile.
Currently in my Terminal, every shell prompt looks like ComputerName: FooDir UserName$. The UserName part simply wastes too much space out of my precious 80 columns. Is there a way to suppress it?
The prompt is defined by the environment variable PS1 which you can define in .bash_profile.
To edit it, open or create the (hidden) file .bash_profile:
nano .bash_profile
and add a line that says
export PS1=""
Between the quotation marks, you can insert what you would like as your terminal prompt. You can also use variables there:
\d – date
\t – time
\h – hostname
\# – command number
\u – username
\W – current directory (e.g.: Desktop)
\w – current directory path (e.g.: /Users/Admin/Desktop)
The default prompt for common Linux distributions would be \w $, which evaluates to ~ $ in your home directory or e.g. /Users $ somewhere else. There are also website (like this one) that can help you with building your prompt.
If you want to remove the UserName part, your choice would be \h: \w$.
Once you made your changes, save the file with Control+o, Return, Control+x.
Here's an excellent article with a full list of Variables and Colors:
Customize your Shell Command Prompt
For a simple, minimalistic prompt, you can try this. Add the following line to your .bash_profile or simply test it first by running it in your terminal:
export PS1="\[\033[0m\]\w\$ "
It'll look something like this:
Here's my Prompt (source), also very simple:
export PS1="\[\033[1;97m\]\u: \[\033[1;94m\]\w \[\033[1;97m\]\$\[\033[0m\] "
2019 onwards, MacOS default shell is Z Shell. To customize command prompt, add a file named .zshrc in user home and put following line that sets a PS1 environment variable with desired prompt format:
export PS1="[%n]%~> "
Open new terminal
This is result of following format expansion:
%n User name
%~ Current directory
See full list of available expansions here.
