Adding your Git branch to your command prompt

show-branch.md

To show your active Git branch in your command prompt, you will need to do the following:

• If you are on a Mac, you can add the code shown below to your .bash_profile file.
• If you are on Linux, you will add the code shown below to your .bashrc file.
• If you are on Windows, you probably aren't reading this because Windows provides this behavior by default.

The Script

parse_git_branch() {
  git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="\w\[\033[36m\]\$(parse_git_branch) \[\033[00m\] > "

Or, another option:

function parse_git_branch () {
  git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
 
RED="\[\033[0;31m\]"
YELLOW="\[\033[0;33m\]"
GREEN="\[\033[0;32m\]"
NO_COLOR="\[\033[0m\]"
 
PS1="$GREEN\u@\h$NO_COLOR:\w$YELLOW\$(parse_git_branch)$NO_COLOR\$ "

For Linux users - you will need to paste code at the end of the .bashrhc file. Otherwise, variable may be overwritten by normal processing.

If you are on Windows, you probably aren't reading this because Windows provides this behavior by default.

You're making assumptions that may not be correct.

Git for Windows does this, yes. But MSYS2 does not, and bash for windows doesn't either (IIRC).

I like this incantation better:

parse_git_branch () {
  ref=$(git symbolic-ref HEAD 2> /dev/null) || return
  echo "${ref#refs/heads/}"
}
