I've put it in my profile. export PS4=' ${BASH_SOURCE}:${LINENO}(${FUNCNAME[0]}) '

Really nice. You could put this into a function within your profile. shdebug() {env PS4=' ${BASH_SOURCE}:${LINENO}(${FUNCNAME[0]}) ' sh -x $1; } This would mean you could debug a shell script nice and easy: shdebug /path/to/

Works great if you don't forget the space between { and env. That's to say : shdebug() { env PS4=' ${BASH_SOURCE}:${LINENO}(${FUNCNAME[0]}) ' sh -x $1; }
