Check These Out

Extract neatly a rar compressed file
It's also possible to delay the extraction (echo "unrar e ... fi" |at now+20 minutes) wich is really convenient!

HourGlass
Displays an animated hourglass for x amount of seconds

check open ports without netstat or lsof

Ask user to confirm
Returns true if user presses the key. Use it like $ Confirm "Continue" && do action

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

the -x option is for binding to a shell command

Process command output line by line in a while loop
This snippet allows to process the output of any bash command line by line.

List out classes in of all htmls in directory
Lists out all classes used in all *.html files in the currect directory. usefull for checking if you have left out any style definitions, or accidentally given a different name than you intended. ( I have an ugly habit of accidentally substituting camelCase instead of using under_scores: i would name soemthing counterBox instead of counter_box) WARNING: assumes you give classnames in between double quotes, and that you apply only one class per element.
