Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

replace strings in file names
Uses vi style search / replace in bash to rename files. Works with regex's too (I use the following a script to fixup / shorten file names): # Remove complete parenthetical/bracket/brace phrases rename 's/\(.*\)//g' * rename 's/\[.*\]//g' * rename 's/\{.*\}//g' *

Replaces a color in a PDF document, useful for removing a dark background before printing.
The pdf is first converted to a bitmap, so change "-density" to match your printer resolution. Also be careful about the RAM required. In this example rgb(0,0,0) is replaced by rgb(255,255,255), change to suit your needs.

view the system console remotely
This will view the console and assumes the screen is 80 characters wide. Use /dev/vcs2 for the next virtual console.. etc.

List only the directories
This command would be useful when it is desirable to list only the directories. 'egrep' chooses only the lines that begin with 'd'.

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Chrome sucks

File rotation without rename command
Rotates log files with "gz"-extension in a directory for 7 days and enumerates the number in file name. i.e.: logfile.1.gz > logfile.2.gz I needed this line due to the limitations on AIX Unix systems which do not ship with the rename command.

burn a isofile to cd or dvd
cdrecord must be installed. usefull alias: $alias burniso='cdrecord -v dev=/dev/cdrom' now iso burning is like. $burniso image.iso
