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.

Extract the MBR ID of a device

Useful when you want to know the mbrid of a device - for the purpose of making it bootable. Certain hybridiso distros, for eg the OpenSUSE live ISO uses the mbrid to find the live media. Use this command to find out the mbrid of your USB drive and then edit the /grub/mbrid file to match it.

Silently deletes lines containing a specific string in a bunch of files

This command will find all occurrences of one or more patterns in a collection of files and will delete every line matching the patterns in every file

Salvage a borked terminal

This works in some situations where 'reset' and the other alternatives don't.

Quick syntax highlighting with multiple output formats

You can specify various output formats, theme styles, etc. $ python -m pygments -o source.png source.py $ python -m pygments -o source.rtf source.py Check available output formats, styles, etc.: $ python -m pygments -L Find pygments module here: http://pygments.org/

Unzip multi-part zip archive

Assuming you have a multi-part archive like "archive.zip archive.z01 archive.z02 ...", unzip will not handle these correctly. If you "fix" the parts into one big file with zip -F before, it works.

list block devices

Shows all block devices in a tree with descruptions of what they are.

Record audio and video from webcam using mencoder

Record audio to MP3 stream and video to MPEG-4 stream from webcam to AVI file using mencoder. Gives floating point exception in some mencoder versions.

connect to all screen instances running

connects to all the screen instances running.

updatedb for MAC OSX

MAC OSX doesn't come with an updatedb command by default, this will emulate the updatedb thats on a typical Linux OS. Simply add it to your ~/.bash_profile

Synchronise a file from a remote server

You will be prompted for a password unless you have your public keys set-up.
