This finds a process id by name, but without the extra grep that you usually see. Remember, awk can grep too!

This example uses the -exec option to move all matching files into a backup directory
It's hard to beat C. This is just slightly faster than the bc version on my machine.
Requirements: libgmp headers, gcc.
Same game as #10096 . loop as many times as you like.

Consider the following simple situation [ reading something using while and read ]
[See script 1 in sample output]
The variable var is assigned with "nullll" at first. Inside the while loop [piped while] it is assigned with "whillleeee". [Onlly 2 assignments stmts]. Outside the loop the last assigned value for "var" [and no variable] inside the while can't be accessed [Due to pipe, var is executed in a sub shell].
In these type of situation variables can be accessed by modifying as follows.
[See script 2 in sample output]

Add an alias to your .bashrc that allows you to issue the command xkcd to view (with gwenview) the newest xkcd comic... I know there are thousands of them out there but this one is at least replete with installer and also uses a more concise syntax... plus, gwenview shows you the downloading progress as it downloads the comic and gives you a more full featured viewing experience.
For those of us that still uses lynx :)
This doesn't work in bash, but in zsh you can typeset -T to bind a scalar variable to an array. $PATH and $path behave this way by default.
