The command could show you all conecctions if you skip "grep ESTABLISHED"

The initial version of this command also outputted extra empty lines, so it went like this:

192.168.166.48

127.0.0.1

This happened on Ubuntu, i haven't tested on anything else.

I'm working in a group project currently and annoyed at the lack of output by my teammates. Wanting hard metrics of how awesome I am and how awesome they aren't, I wrote this command up.

It will print a full repository listing of all files, remove the directories which confuse blame, run svn blame on each individual file, and tally the resulting line counts. It seems quite slow, depending on your repository location, because blame must hit the server for each individual file. You can remove the -R on the first part to print out the tallies for just the current directory.

and, a lot uglier, with sed:

Edit:

Wanted to be shorter than the perl version. Still think that the perl version is the best..

Busiest seconds:

Breaks down and numbers each line and it's fields. This is really useful when you are going to parse something with awk but aren't sure exactly where to start.

converts any number on the 'stdin' to SI notation. My version limits to 3 digits of precious (working with 10% resistors).

a variation of avi4now's command - thanks by the way!

That one works on Linux. On BSD and Solaris, the ifconfig output is much easier to parse:

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.:)

#!/bin/bash

ps -u $USER |grep $1 | awk '{ print $1}'| xargs kill

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}
