Well this can come handy , when you don't feel like playing with pid rather if you know

the process name say "firefox",it would kill it.The script given below would kill the process with its name given as first parameter , though not robust enough to notify that process doesn't exist , well if you know what you are doing that's wouldn't be a problem.:)

Also useful with iostat, or pretty much anything else you want timestamped.

grep's -c outputs how may matches there are for a given file as "file:N", cut takes the N's and awk does the sum.

Handy when you need to create a list of files to be updated when subversion is not available on the remote host. You can take this tar file, and upload and extract it where you need it. Replace M and N with the revisions specific to yours. Make sure you do this from an updated (svn up) working directory.

awk can clear the screen while displaying output. This is a handy way of seeing how many lines a tail -f has hit or see how many files find has found. On solaris, you may have to use 'nawk' and your machine needs 'tput'

Beeps on mouse's every move. Bear in mind that, at least on Ubuntu, /dev/input/mice can be read only by root.

Basically it creates a typical word list file from any normal text.

Skype has an internal regex which depicts the emoticons it supports. However you cannot simply search the binary file for it. This small 181 character line will do just that, provided skype is running. And of course, only works in linux.

Use this if you don't have access to GNU grep's -B option.

Helpful when we want to do mass file renaming(especially mp3s).

This will extract all of the urls from a firefox session (including urls in a tab's history). The sessionstore.js file is in ~/.mozilla/firefox/{firefox profile}

w3m is a commanline web browser, full of options, I used -dump_head for less unnecessary page download.

With awk, I can retrieve dynamic changes in webpages in this very econnomical fashion

Speaks whatever comes in via stdin (-v pt = portuguese, default = englisg)

..speech part of keyboard event talker. Made to accomplish a simple alarm central based on a cheap keyboard circuit. This way I have one zone per direct keypress. Depends on keypress.sh. It speaks out loud wich zone (key) has been pressed ( faulted ). Here is keypress.sh :

#!/bin/bash

# keypress.sh: Detect a user keypress ("hot keys").

echo

old_tty_settings=$(stty -g) # Save old settings (why?).

stty -icanon

Keypress=$(head -c1) # or $(dd bs=1 count=1 2> /dev/null)

# on non-GNU systems

aplay -q /home/mm/bash/beep-1.wav

echo

echo "Chamada quarto \""$Keypress"\"."

echo

stty "$old_tty_settings" # Restore old settings.

exit 0

What do you do when nmap is not available and you want to see the hosts responding to an icmp echo request ? This one-liner will print all hosts responding with their ipv4 address.

It is a great idea, however what about when you want to edit that file? ...Serious pain in the butt.

I ran into this today in that my only copy of a CSS file was "compressed" with no newlines.

I whipped this up and it converted back into nice human readable CSS :-)

It could be nicer, but it does the job.
