Check These Out

Count opening and closing braces in a string.
This function counts the opening and closing braces in a string. This is useful if you have eg long boolean expressions with many braces and you simply want to check if you didn't forget to close one.

Command template, executing a command over multiple files, outputing progress and fails only
This is a command template for achiving the following: * loop over files --> find -name "" | while read file; do ...; done * output progress --> echo -n . * execute some command on each file and save output for later usage --> output=$() * if command failed, open subshell and echo newline --> || (echo;...;...;) * echo output of command --> echo "$output"

Upload folder to imageshack.us (forum)
Each file in the current folder is uploaded to imageshack.us If the folder contains other filetypes change: $for files in * to: $for files in *.jpg (to upload ONLY .jpg files) Additionally you can try (results may vary): $for files in *.jpg *.png The output URL is encased with BB image tags for use in a forum.

Cleanup Python bytecode files
This command will erase all bytecode versions of Python modules under the current directory.

Not a kismet replacement...
If you're like some individuals who rely on ndiswrapper and cannot use kismet, this command may be of service. watch -n .5 "iwlist wlan0 scan | egrep 'ESSID|Encryption'" Or... watch -n .5 "iwlist wlan0 scan | egrep 'ESSID|Encryption' | egrep 'linksys'" :-) Hopefully you'll find some dd-wrt compatible routers.

Quick case-insenstive partial filename search
This is a simple command, but extremely useful. It's a quick way to search the file names in the current directory for a substring. Normally people use "ls *term*" but that requires the stars and is not case insensitive. Color (for both ls and grep) is an added bonus.

Skip to next selection in playlist
Uses process signal to play next selection

mplayer -vo aa foo.mpg
mplayer -vo caca will give you a similar result but in color

online MAC address lookup

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"
