commandlinefu.com is the place to record those command-line gems that you return to again and again.
Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.
If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/
You can sign-in using OpenID credentials, or register a traditional username and password.
First-time OpenID users will be automatically assigned a username which can be changed after signing in.
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.

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.

Don't sort the path because there may be two programs with the same name and the first in the path should show up first. Also, take advantage of grep regular expression and remove the sed scripts. Handle empty string cases.
function sepath { echo ${PATH} | tr : \\n | while read L; do find ${L:-"."} -type d ! -path ${L:-"."} -prune -o \( -type f -o -type l \) 2>/dev/null | grep -i "${L:-"."}/.*${*}"; done; }thanks for your comment arcege but your modifications are not efficients.
for example:
sepath ^pswill not work with your hack.
however, you right, i should not sort the PATH.
