In Debian based distros, this command will list 'binutils' package details which contains 'nm' command. You can replace 'nm' to any other command.

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 .

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.

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.

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

(edit: corrected)

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.

binary=({0..1}{0..1}{0..1}{0..1})

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

netcat -l -p 55555

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

- The other variables have obvious names.
