I have my terminal and prompt set up perfectly on my MacBook but when setting up my PC I ran into an issue, It wont display my current git branch & I am getting an error. Any help would be greatly appreciated.
Below Text Is My ~/.bashrc & ~/.bash_profile

export PS1;
Below Is The Error I Get When I "source ~/.bashrc"
\bash: command substitution: line 1: syntax error near unexpected token )'
\bash: command substitution: line 1: \git_branch)'
CodePudding user response:
I prefer to use a PROMPT_COMMAND
that will be executed every time you get a prompt and will therefore update it accordingly.
Example that goes into .bashrc
:
tputps () {
echo -n '\['
tput "$@"
echo -n '\]'
}
prompt_builder () {
# username
tputps setaf 2
echo -n '\u'
# if I'm in a git repo, add some info from that:
commit=$(git rev-parse -q --short HEAD 2>/dev/null)
if [[ -n $commit ]]; then
tputps setaf 140
echo -n " $commit"
fi
branch=$(git branch --show-current 2>/dev/null)
if [[ -n $branch ]]; then
tputps setaf 10
echo -n " $branch"
fi
# directory
tputps setaf 208
echo -n ' \w'
tputps sgr0 0
}
prompt_cmd () {
PS1="$(prompt_builder) \$ "
}
export PROMPT_COMMAND=prompt_cmd
