Note that the file at the given path will have the contents of the (still) deleted file, but it is a new file with a new node number; in other words, this restores the data, but it does not actually "undelete" the old file. I posted a function declaration encapsulating this functionality to http://www.reddit.com/r/programming/comments/7yx6f/how_to_undelete_any_open_deleted_file_in_linux/c07sqwe (please excuse the crap formatting).
5N="filepath" ; P=/proc/$(lsof +L1 | grep "$N" | awk '{print $2}')/fd ; ls -l $P | sed -rn "/$N/s/.*([0-9]+) ->.*/\1/p" | xargs -I_ cat $P/_ > "$N" -
This command will kill all processes using a directory. It's quick and dirty. One may also use a -9 with kill in case regular kill doesn't work. This is useful if one needs to umount a directory. Show Sample Output
5lsof|grep /somemount/| awk '{print $2}'|xargs kill -
5u=`curl -d 'dl.start=Free' $(curl $1|perl -wpi -e 's/^.*"(http:\/\/rs.*)" method.*$/$1/'|egrep '^http'|head -n1)|grep "Level(3) \#2"|perl -wpi -e 's/^.*(http:\/\/rs[^\\\\]*).*$/$1/'`;sleep 60;wget $u
-
5grep "install " /var/log/dpkg.log | awk '{print $4}' | xargs apt-get -y remove --purge

You can tell GCC to automatically select optimization commands and produce optimized code for the local machine (the one compiling the code), but you can't normally see what switches have been selected and used unless you append a "-v" and pause compilation. Show Sample Output
5cc -march=native -E -v - </dev/null 2>&1 | grep cc1 -
'jot' does not come with most *nix distros, so we need to use seq to make it work. This version tested good on Fedora 11.
5for x in `seq 0 25 $(curl "http://www.commandlinefu.com/commands/browse"|grep "Terminal - All commands" |perl -pe 's/.+(\d+),(\d+).+/$1$2/'|head -n1)`; do curl "http://www.commandlinefu.com/commands/browse/sort-by-votes/plaintext/$x" ; done > a.txt -
You're behind on your TV catch-up, but how far behind? This command tries to open mplayer against all files in the current dir. If it's a video file it will contain ID_LENGTH, which is summed and output in hours, minutes and seconds. Someone better at awk could probably reduce this down a lot. Show Sample Output
5mplayer -vo dummy -ao dummy -identify * 2>&1 | grep ID_LENGTH | sed 's/.*=\([0-9]*\)/\1/' | xargs echo | sed 's/ /+/g' | bc | awk 'S=$1; {printf "%dh:%dm:%ds\n",S/(60*60),S%(60*60)/60,S%60}' -
Quick and easy way to find out which php.ini file is being used. Especially useful if you just need to find the location of the file for editing purposes. Show Sample Output
5php -i | grep php.ini -
Parallel does not suffer from the risk of mixing of output that xargs suffers from. -j+0 will run as many jobs in parallel as you have cores. With parallel you only need -0 (and -print0) if your filenames contain a '\n'. Parallel is from https://savannah.nongnu.org/projects/parallel/
5find . -type f | parallel -j+0 grep -i foobar -
Get your weather from a weather station just blocks from your home. Go to http://www.wunderground.com/wundermap/ and find a weather station near you. Click on a temperature bubble for that area. When the window pops up, click on hypertext link with the station ID, then on the bottom right of the page, click on the Current Conditions XML. Thats your link! Good luck! Show Sample Output
5lynx -dump http://api.wunderground.com/weatherstation/WXCurrentObXML.asp?ID=KCALOSAN32 | grep GMT | awk '{print $3}' -
5git reflog show | grep '}: commit' | nl | sort -nr | nl | sort -nr | cut --fields=1,3 | sed s/commit://g | sed -e 's/HEAD*@{[0-9]*}://g'

The original was a little bit too complicated for me. This one does not use any variables.
5pronounce(){ wget -qO- $(wget -qO- "http://www.m-w.com/dictionary/$@" | grep 'return au' | sed -r "s|.*return au\('([^']*)', '([^'])[^']*'\).*|http://cougar.eb.com/soundc11/\2/\1|") | aplay -q; } -
5svn log -r {`date +"%Y-%m-%d" -d "1 month ago"`}:HEAD|grep '^r[0-9]' |cut -d\| -f2|sort|uniq -c

Yet another x11grab using ffmpeg. I also added mic input to the capturing video stream using alsa. Yet I need to find out how to capture audio which is currently playing. Show Sample Output
5ffmpeg -f alsa -itsoffset 00:00:02.000 -ac 2 -i hw:0,0 -f x11grab -s $(xwininfo -root | grep 'geometry' | awk '{print $2;}') -r 10 -i :0.0 -sameq -f mp4 -s wvga -y intro.mp4 -
The cut should match the relevant timestamp part of the logfile, the uniq will count the number of occurrences during this time interval. Show Sample Output
5grep <something> logfile | cut -c2-18 | uniq -c -
I've been using it in a script to build from scratch proxy servers. Show Sample Output
5ifconfig eth0 | grep "inet " | cut -d ':' -f2 | awk '{print $1}' -

create the function then run 'yt-chanrip username' to download that user's entire channel. uses youtube-dl and the GData API. similar to http://www.commandlinefu.com/commands/view/3154/download-youtube-playlist
5yt-chanrip() { for i in $(curl -s http://gdata.youtube.com/feeds/api/users/"$1"/uploads | grep -Eo "watch\?v=[^[:space:]\"\'\\]{11}" | uniq); do youtube-dl --title --no-overwrites http://youtube.com/"$i"; done } - ‹ First < 5 6 7 8 9 > Last ›
