Git Bash Prompt- Current Branch Name Stops Showing After Git Command

Question

Using GitBash with Git for Windows, my PS1 variable is set to display current branch as such:

$ echo $PS1
\[\033]0;$TITLEPREFIX:${PWD//[^[:ascii:]]/?}\007\]\n\[\033[32m\]\u@\h \[\033[35m\]$MSYSTEM \[\033[33m\]\w\[\033[36m\]`__git_ps1`\[\033[0m\]\n$

This works fine to start, for example my prompt starts out like

myuser@mypc MINGW64 /c/git/myrepo (master)
$

However, after I run any git command, the current branch portion is omitted until I restart the shell.

myuser@mypc MINGW64 /c/git/myrepo (master)
$ git branch
* master
  myOtherBranch

myuser@mypc MINGW64 /c/git/myrepo
$

But if I run __git_ps1 it still tells me the correct value:

myuser@mypc MINGW64 /c/git/myrepo
$ echo `__git_ps1`
(master)

myuser@mypc MINGW64 /c/git/myrepo
$

Any ideas what could be happening, or how I could go about diagnosing/fixing this issue?

So I was able to get things working again based off this and the info already here in this question. I added the below to my .bashrc file and all is good once again. I'm not sure what the root cause of the issue might be, but this seems to be a good workaround for me.

update_PS1 () {
  PS1="\[\033]0;$TITLEPREFIX:${PWD//[^[:ascii:]]/?}\007\]\n\[\033[32m\]\u@\h \[\033[35m\]$MSYSTEM \[\033[33m\]\w\[\033[36m\]`__git_ps1`\[\033[0m\]\n$ "
}
shopt -u promptvars
PROMPT_COMMAND=update_PS1

Answer 2

I have the same problem. After I run any git command, the current branch name is disappear. First I use the tip from answer https://stackoverflow.com/a/43659303/8156156. Works well.

But after investigation I find that I have not only this problem but other with bash. I write it in https://github.com/git-for-windows/git/issues/1153#issuecomment-308110681.

I don't know a root of these problems but workaround that works for me (for both problems) is install 32-bit version of Git for Windows (Git-2.13.1-32-bit).

Ubuntu: Show your branch name on your terminal Add these lines in your ~/.bashrc file

# Show git branch name
force_color_prompt=yes
color_prompt=yes
parse_git_branch() {
 git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}
if [ "$color_prompt" = yes ]; then
 PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[01;31m\]$(parse_git_branch)\[\033[00m\]\$ '
else
 PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w$(parse_git_branch)\$ '
fi
unset color_prompt force_color_prompt

Close and open your terminal

All I had to do is place a blank line at the end of .bashrc, and that solved it.
