Well, you saw my command line to list installed debian packages;
i don't have it on hand here, i'll dig it up from my archives.
A nice function, not quite a command line hack, that i keep in my
.bash_profile:
function where () { type -type ${1+"$@"} | grep -v file 1>&2 ; type -all \
${1+"$@ "} | awk '((NF == 3) && ($3 !~ /\$\*\;/)) {print $NF}' ; }
This will give me a list of available binaries of a certain name,
e.g. on garcia.efn.org:
---
{garcia!pat_e#ttyr3:/home02/members/p/pat_e} 0:507 bash$ where perl
/usr/local/gnu/bin/perl
/bin/perl
/usr/bin/perl
/usr/local/bin/perl
{garcia!pat_e#ttyr3:/home02/members/p/pat_e} 0:508 bash$

If we want to get into shell scripts, stevev has a nice WHOIS wrapper
i find very convenient i could post (it's pretty long)
