Commands using grep (1,935)

Instead of having someone else read you the Digg headlines, Have OSX do it. Requires Curl+Sed+Say. This could probably be easily modified to use espeak for Linux.
-2IFS=`echo -en "\n\b"`; for i in $(curl http://feeds.digg.com/digg/container/technology/popular.rss | grep '<title>' | sed -e 's#<[^>]*>##g' | tail -n10); do echo $i; echo $i | sed 's/^/Did you hear about /g' | say; sleep 30; done -
-2/sbin/ifconfig eth0 | grep 'inet6 addr:' | awk {'print $3'}
-
-2ifconfig eth0 | grep 'HWaddr' | awk '{print $5}'
-
-2ps auxwww | grep outofcontrolprocess | awk '{print $2}' | xargs kill -9

-
If your site is struck with the white screen of death you can find the syntax error quickly with php lint
-2find -name "*.php" -exec php -l {} \; | grep -v "No syntax errors" -
xargs avoids having to remember the "{} \;" (although definitely a useful thing to know. Unfortunately I always forget it). xargs version runs 2x faster on my test fwiw. edit: fixed to handle spaces in filenames correctly.
-2find . -name "*.php" -print0 | xargs -0 grep -i "search phrase" -
#Sample Usage: # git commit -m"Jira #404 - `whatthecommit`" # Show Sample Output
-2curl -s http://whatthecommit.com/ | tr -s '\n' ' ' | grep -so 'p>\(.*\)</p' | sed -n 's/..\(.*\)..../\1/p' -
This heavy one liner gets all the files in the "/music/dir/" directory and filters for non 44.1 mp3 files. After doing this it passes the names to sox in-order to re-sample those files. The original files are left just in case.
-2file /music/dir/* | grep -v 44.1 | sed 's/:.*//g' | grep .mp3 | { while IFS= read; do filebak="\"$REPLY.original\""; file="\"$REPLY\""; mv $file $filebak; sox -t mp3 $filebak $file rate 44k; done; }; -
-2wget -O- -q http://www.nomachine.com/download-package.php?Prod_Id=2067 | sed -n -e 'H;${x;s/\n/ /g;p;}' | sed -e "s/[Hh][Rr][Ee][Ff]=\"/\n/g" | cut -d "\"" -f1 | sort -u | grep deb$
-
-2lynx -dump http://www.domain.com | grep http| awk '{print $2 }'

Of course, this command must be executed at a GRID User Interface lhcb - name of your VO, substitute it with the one you are interested it. Show Sample Output
-2echo `lcg-infosites --vo lhcb ce | cut -f 1| grep [[:digit:]]| tr '\n' '+' |sed -e 's/\ //g' -e 's/+$//'`|bc -l -
I use this command, within a cron job, to kill XMMS after a certain amount of time. This command returns the PID used by XMMS, and gets passed to the kill command. Another alternative would be ps aux | grep xmms | grep -v grep | awk '{ print $2 }' | xargs kill
-2kill `ps aux | grep xmms | grep -v grep | awk '{ print $2 }'` -
Mac OSX creates resource forks (http://en.wikipedia.org/wiki/Resource_fork) for every file, which are extremely annoying when transferring projects over to an Ubuntu server for instance
-2rm -f `find ./ | grep "\.\_.*"` -
I used this to mass install a lot of perl stuff. Threw it together because I was feeling *especially* lazy. The 'perl' and the 'module' can be replaced with whatever you like.
-2apt-cache search perl | grep module | awk '{print $1;}' | xargs sudo apt-get install -y -
This is what we use. You can grep -v 127.0.0.1 if you wish.
-2ifconfig | grep -o "inet [^ ]*" | cut -d: -f2 -
This is an attempt to get a command which I can alias. It's ugly but it works. I'm hoping someone can suggest a cleaner version. I have tried.... # alias kfire="for i in $( ps aux | grep [F]irefox | awk \'{print $2}\' ); do kill $; done" # alias kfire=`kill $(ps aux | grep [F]irefox | awk '{print $2}' | tr '\n' ' ')` # alias kfire='ps au | grep -i [F]irefox | awk \'{ print $2 \'} ' and they all fail in a .bashrc I've tried escaping the quotes and can't find a way to make the single quotes ' that awk wants work. Maybe I'm just stubborn but I don't want to put in a little #!/bin/bash file just so I can kill a firefox process all in one stroke. This script works (it kills the process before it errors out)... it's just ugly and there may be a pretty way to do this. Show Sample Output
-2alias kfire='for i in `ps aux | grep [F]irefox `; do echo $i; kill $(($i)); done; ' -
Identical output but a different way without having to shoot with the Awk cannon :)
-2df | grep -w '/media/mountpoint' | cut -d " " -f 1 -
Same output Show Sample Output
-2df | grep -w '/media/armadillo' | cut -d " " -f 1 -
This command is useful when you want to check your nic's mac address, if you're interested in your wireless interface, use its ID instead "eth". This command was tested under Ubuntu and Slackware GNU/Linux. Show Sample Output
