Sorry bout that, I knew it was a bit fragile. Was rather comical reading Junio's recent message about all the things not to do if you want portable shell code and noticing my 6 line script did 90% of them ;o) Strange though, I downloaded Bash 3.2 and gave it a try and didn't see the problem here..

Wanna try this small change, to see if it helps? :

#!/bin/bash BR=$(git symbolic-ref HEAD 2>/dev/null) || { echo "$@" ; exit ; } BR=${BR#refs/heads/} REL=$(git rev-parse --show-prefix) REL="${REL%\/}" LOC="${PWD%/$REL}" echo "[$BR!${LOC/*\/}${REL:+/$REL}]$ "
