Undocumented syntax, but should work on every shell. It'll list all directories in the current one. Change `*/` into globbing `**/` for recursivity. Show Sample Output
Resizes all images in the curent directory to x resolution. It is better than `mogrify -resize *.jpg` because of independence from extension of image (e.g. .jpg and .JPG) (: Show Sample Output
At times I find that I need to loop through a file where each value that I need to do something with is not on a separate line, but rather separated with a ":" or a ";". In this instance, I create a loop within which I define 'IFS' to be something other than a whitespace character. In this example, I iterate through a file which only has one line, and several fields separated with ":". The counter helps me define how many times I want to repeat the loop.

Renames all files ending in "_test.rb" to "_spec.rb"
The example runs 'puppet' in a loop for 10 times, but exits the loop before if it returns 0 (that means "no changes on last run" for puppet).
I had trouble with accent I could do a simple mv by hand but it is not efficient. I found this online http://www.unix.com/shell-programming-and-scripting/158635-remove-spanish-accent-file-name.html but I could not specify the accented letter direcly because it is not in the same encoding as my cli so I changed the char for their octal value. to add accent I use this table http://linux.about.com/library/cmd/blcmdl7_iso_8859-1.htm and add the values to the tr part. the other "duplicates" where not working for me. comment to help me better this script. :) Show Sample Output
Basically, \033[ is a semi-portable unix escape character. It should work in linux, osx, bsd, etc. The first option is 38. This tells whatever is interpreting this (and this is merely convention) that a special color sequence follows. The next option is 5 which says that the next option will specify a color ? {0..256} of course. These options, as you can see, are separated by a single `;` and the entire escape sequence is followed by a mandatory `m`. The second escape sequence (following "COLOR") is simply to clear all terminal attributes (for our purposes, it clears color). This for loop is helpful for testing all 256 colors in a 256 console (note: this will not work in a standard Linux tty console) or to see which number corresponds to which color so that perhaps you can use it!

Converts all ogg files to mp3 files in the current directory.
Searches in order of the directories of $PATH. Stops after finding the entry; looks for only that fileName. Works in Bourne, Korn, Bash and Z shells. Show Sample Output
I find the other timers are inaccurate. It takes some microseconds to perform the date function. Therefore, using date/time math to calculate the time for us results in millisecond accuracy. This is tailored to the BusyBox date function. May need to change things around for GNU date function. Show Sample Output
For this example, all files in the current directory that end in '.xml.skippy' will have the '.skippy' removed from their names.
