How to customize the shell prompt in the VS Code terminal on macOS

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.

Editing ~/.bash_profile doesn't customize command-line prompt properly

Related Issue: How to change the terminal prompt to just current directory?
I have added export PS1="\w\$ " to my ~/.bash_profile, but the prompt for the command line just displays this:
\w$
It recognizes the backslash escape for the $ character, but not for the filepath. It does the same thing when I use a capital 'W'.
The problem was that my terminal is running zsh. I created ~/.zshrc and wrote the following code:
PROMPT="%/\$ "
I referred to this resource to find the appropriate characters for displaying the current file path: ZSH Prompt Expansion.

How to config the emacs shell prompt in OSX

I want the shell of emacs show the absolute path. My system shell is config like following
export PS1='\u#MacAir:\w$ '
I have try this way. It can't work for me .
PS: My emacs is emacs24
Solution : Add export PS1='\u#MacAir:\w$ ' into ~/.bashrc
The shell prompt is not the responsibility of Emacs but of the shell you're running. Assuming you're using bash, check out the following question+answer:
https://askubuntu.com/questions/388913/how-to-make-ps1-display-full-path-name
which recommends the use of the special escape sequence $PWD:
export PS1='\u#MacAir:$PWD$ '
Put the above line in your ~/.bashrc file for it to take effect in Emacs (as well as in normal terminals).

.bash_profile PS1 to show current directory folder and a $ MAC osx

In my .bash_profile I currently have
PS1="$ "
which in my terminal returns '$ '
I want to show the current folder as well.
if I run the command, pwd
/Users/Me/Sites/
I would want my bash prompt to return
'Sites$'
Thanks for all your help.
try this:
PS1='\[\033[01;32m\]\u#\h\[\033[01;34m\] [\w]\[\033[00m\]'
Note that if you don't want brackets or colors surrounding the current directory, you can use the simpler:
export PS1="\W$ "

How to change shell prompt in Unix?

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"
