Save the script as: sort_file

Usage: sort_file < sort_me.csv > out_file.csv

This script was originally posted by Admiral Beotch in LinuxQuestions.org on the Linux-Software forum.

I modified this script to make it more portable.

Infinitely plays beeps with sinusoidally changing sound frequency. Ideal for alarm on an event.

It's the same command as submitted, but first with a command to make all characters green. It's the only way it looked "matrix-like" on my gnome-terminal.

When you use a "for" construct, it cycles on every word. If you want to cycle on a line-by-line basis (and, well, you can't use xargs -n1 :D), you can set the IFS variable to .

This will create a permanent alias to colorize the search pattern in your grep output

Handy use of bc in the command line. No need to get 'into' the bc to perform calculations

Empties all files in /var/log over 5000k. Useful if /var goes crazy or if you just haven't cleaned up in a while.

Found this one little more for me. This one removes the perl dependency (from command 2535).

defines a handy function for quick calculations from cli.

once defined:

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.

When plumbers use pipes, they sometimes need a T-joint. The Unix equivalent to this is 'tee'. The -a flag tells 'tee' to append to the file, rather than clobbering it.

Tested on bash and tcsh.

Set an alarm to starts in specific time.

get desired info from machine and pipe it txt file.

You can replace "sort -nu" with "sort -u" for a word list sorted or "sort -R" for a random-sorted line

(edit: corrected)

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

If you should happen to find yourself needing some binary numbers, this is a quickie way of doing it. If you need more digits, just add more "{0..1}" sequences for each digit you need. You can assign them to an array, too, and access them by their decimal equivalent for a quickie binary to decimal conversion (for larger values it's probably better to use another method). Note: this works in bash, ksh and zsh. For zsh, though, you'll need to issue a setopt KSH_ARRAYS to make the array zero-based.

Yes, it's useless.

Pipe whatever you want to this function, it will, if everything goes well, be redirected to a channel or a user on an IRC server.

Please note that :

- I am not responsible of flood excesses you might provoke.

- that function does not reply to PINGs from the server. That's the reason why I first write in a temporary file. Indeed, I don't want to wait for inputs while being connected to the server. However, according to the configuration of the server and the length of your file, you may timeout before finishing.

- Concerning the server, the variable content must be on the form "irc.server.org 6667" (or any other port). If you want to make some tests, you can also create a fake IRC server on "localhost 55555" by using

- Concerning the target, you can choose a channel (beginning with a '#' like "#chan") or a user (like "user")

- The other variables have obvious names.

Nice reading in the morning on the way to work, but sadly the .tar.gz for the whole issue 66 is not on phrack's website yet. So use wget to download.

^Hexadecimal Ten minus Octal Ten is Eight(in Decimal).

^Hexadecimal AF and Octal 257 are both Decimal 175.

Here the pattern is '*.jar', you could pass in any pattern.

Another, maybe nicer way to do this is

You could replace sed with tr

use to execute a block of code only if $var is numeric
