Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

search argument in PATH

accept grep expressions

without args, list all binaries found in PATH

for L in `echo :$PATH | tr : '\n'`; do F=${L:-"."}/fileName; if [ -f ${F} -o -h ${F} ]; then echo ${F}; break; fi; done

Functions: echo tr

Searches in order of the directories of $PATH. Stops after finding the entry; looks for only that fileName. Works in Bourne, Korn, Bash and Z shells.

Know a better way?

If you can do better, submit your command here.

What others think

nice! I searched the bash manpage for a while and didn't catch this one. Maybe I should have scrolled. :-) Apparently you can't do this in zsh as the whence builtin will not report a path for something not executable.
