That's an annoying 430ms delay at every prompt, on my box. Does StGIT do
something expensive on every invocation?
Ben Clifford'd solution is pretty much instantaneous, and the following
extends it to StGIT (in a less clean but much faster way):
----------------------------------------------
__prompt_githead() {
__PS_GIT="$(git-symbolic-ref HEAD 2>/dev/null)" || exit
__PS_GIT="$(basename $__PS_GIT)"
echo -n " $__PS_GIT"
__PS_GIT=$(cat "${GIT_DIR:-.git}/patches/$__PS_GIT/current" \
2>/dev/null) || exit
echo -n ":$__PS_GIT"
}
PS1='[\u@\h \W$(__prompt_githead)]\$ '
----------------------------------------------
