Stay in the loop…

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.

Searches $PATH for files using grep

Best to put it in a file somewhere in your path. (I call the file spath)

#!/bin/bash

IFS=:; find $PATH | grep $1

Usage: $ spath php

What others think

A bit shorter version wrapped in function (which is must-do, otherwise you can't use $1):

function path-grep() { dirs=${PATH//:/\ } find $(echo $dirs) | egrep $1 }

Yes as I mentioned in the description you can put it in a file. Which on my machine, ubuntu 9.04 allows you to obtain the users input via $1.

I like how you don't use a for loop. Nice!

Comment by camspiers 244 weeks and 5 days ago

find will recurse. Although it is unusual for a PATH dir to have subdirs, the fact is you may get false matches if they do, and one of the dubdirs has a file matching the name you're looking for.

And really, what is wrong with:

which cat

/bin/cat

Comment by sitaram 244 weeks and 5 days ago

I just find it useful when given a server I don't know. Allows my to quickly determine what mysql tools are installed for example. "which" doesn't really help if you want partial matches.

Comment by camspiers 244 weeks and 4 days ago

aah... partial matches. OK:

( IFS=:; find $PATH | grep pattern )

wrap it in a function and use $1 if you like :)

Comment by sitaram 244 weeks and 4 days ago

For just a listing you could also do:

IFS=: find $PATH -type f

the change to IFS when at the beginning of the line goes only applies for that single command (at least in bash). You see a lot of this in Gentoo Linux. Neat idea.

sitaram: That is awesome! I didn't know about the IFS. I have changed the command to specific : as the custom IFS.
