sh -x is about all i have found for stepping through the script, i agree its rather rough, this is why i usually add debugging code to my script, generally just echoing various things such as variable values and telling me which way certain tests went. i do this like so: [ "$DEBUG" = 1 ] && echo 1>&2 "$PRG: DEBUG: foobar is $foo" then at the start of the script i have: DEBUG=0 when i need debug info i change it to: DEBUG=1 though my main scripts all accept the --debug switch which turns DEBUG=1. works pretty well for me. -- Ethan Benson http://www.alaska.net/~erbenson/
