This is more of a handy how-to than it is a question. A permanent 'howto' as it were. A Perl project I'm working on contains 457 functions (ie. subroutines (ie methods)), and even though I have documentation for all of them, sometimes it is handy to have a list in front of me. This is how I produce the list of all sub-routines within all module files, which includes the module name and sub. % grep -E -r "sub \w+ {" * | grep -v svn | awk '{FS=":"} \ {print $1, " ", $2}' | awk '{FS=" "} {print $1, " ", $3}' ...adapted to pull subs from a single file: % cat lib/ISP/User.pm | grep -E "sub \w+ {" | awk '{print $2}' For efficiency, and so I can remember more readily, my request is for golf, particularly adaption to a Perl one-liner ;) Cheers, Steve
