psg (ps grep) function if you don't have pgrep or don't know how to use it

My variant on this common function. Some highlights: Allows you to override the default ps args of "aux" Uses bracket trick to omit the grep process itself without having to use a second grep Always prints the correct header row of ps output Limitations: Ugly ps error output if you forget to quote your multi word grep argument Show Sample Output

Determine what process is listening on a port on Solaris, without lsof

Can use lsof, but since it's not part of the base OS, it's not always available. Show Sample Output

for x in `ptree | awk '{print $1}'`; do pfiles $x | grep ${PORT} > /dev/null 2>&1; if [ x"$?" == "x0" ]; then ps -ef | grep $x | grep -v grep; fi; done 2> /dev/null

Show the command line of a process that use a specific port (ubuntu)

kill all process that belongs to you

Kills all process that belongs to the user that runs it - excluding bash, sshd (so putty/ssh session will be spared). The bit that says grep -vE "..." can be extended to include ps line patterns that you want to spare. If no process can be found on the hitlist, it will print # NOTHING TO KILL. Otherwise, it will print # KILL EM ALL, with the cull list.

show top 10 most memory hungry process with a simple format of (%mem, pid, short command)

Pros: the format is very simple, there is no need to show every columns, and full command with args the first column is memory consumption % the second column is pid the third is just the command (without full arguments, most application's arguments are too long) You can decide which application to kill then.

batch convert Nikon RAW (nef) images to JPG

converts RAW files from a Nikon DSLR to jpg for easy viewing etc. requires ufraw package

list current ssh clients

Change user within ssh session retaining the current MIT cookie for X-forwarding

When you remotely log in like "ssh -X userA:host" and become a different user with "su UserB", X-forwarding will not work anymore since /home/UserB/.Xauthority does not exist. This will use UserA's information stored in .Xauthority for UserB to enable X-forwarding. Watch http://prefetch.net/blog/index.php/2008/04/05/respect-my-xauthority/ for details.

Convert multiple flac files to mp3

make sure that flac and lame are installed sudo apt-get install lame flac

High resolution video screen recording

$ gorecord foo.mp4 I've tried all of the screen recorders available for Linux and this is easily the best. xvidcap segfaults; VNC is too much hassle. There are alternatives of this command already here that I am just too lazy to reply to. Messing with the frames per second option, -r, 25 seems to be the best. Any lower and the video will look like a flipbook, if it records at all - -r 10 won't - any faster is the same, oddly enough. Edit: CLF doesn't like my long command to add audio, so here it is in the description. $ goaddaudio() ${ $if [ $# != 3 ]; then $ echo 'goaddaudio < audio > < src video > < dst video >' $ return $ fi $ $ f=goaddaudio$RANDOM $ ffmpeg -i "$2" &> $f $ d=$( grep Duration $f | awk '{print $2}' | tr -d ',' ) && $ rm $f && $ ffmpeg -i "$1" -i "$2" -r 25 -ab 192k -ar 44100 -sameq -t $d "$3" $}

Do quick arithmetic on numbers from STDIN with any formatting using a perl one liner.

Good for summing the numbers embedded in text - a food journal entry for example with calories listed per food where you want the total calories. Use this to monitor and keep a total on anything that ouputs numbers.

count how many times a string appears in a (source code) tree

grep -o puts each occurrence in a separate line

Mount directories in different locations

Like symlinked directories, you can mount a directory at a different location. For example mounting a directory from one location in to the http root without having to make your program follow symlinks or change permissions when reading.
