which program is this port belongs to ?

Sometimes you need to use a port that is already opened by some program , and you don't know who to "kill" for it to release - so, now you do !

Find 'foo' in located files

Greps located files for an expression.

Example greps all LaTeX files for 'foo':

locate *.tex | xargs grep foo

To avoid searching thousands of files with grep it could be usefull to test first how much files are returned by locate:

locate -c *.tex

Add a line from 1 file after every line of another (shuffle files together)

After every line in targetfile (empty lines included) insert in a line from addfile. "Save" results to savefile. Addfile should be longer than targetfile since this doesn't loop back to the top of addfile.

/^/R addfile -- says for every line that matches "has a start of line" output a line from the file addfile.

> savefile (optional) -- redirect output to savefile file.

Displays the attempted user name, ip address, and time of SSH failed logins on Debian machines

A variation of a script I found on this site and then slimmed down to just use awk. It displays all users who have attempted to login to the box and failed using SSH. Pipe it to the sort command to see which usernames have the most failed logins.

Show the power of the home row on the Dvorak Keyboard layout

Quick and dirty command that counts how many words can be typed just using the home row on the Dvorak Simplified Keyboard layout from a dictionary file, in this case /usr/share/dict/words.

According to the regular expression supplied, each word must contain all the keys on the Dvorak home row, and no other characters. For comparison, I've shown how many words are installed in my dictionary, how many can be typed with just the Dvorak home row and how many can be typed with just the QWERTY home row in the sample output. Nearly 10 times the amount.

If you want to see the words, remove the -c switch, and each word will be printed out.
