From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

To get shit done in general.
If I need to rename a file, yeah, I can do that by right-clicking it in the file explorer, and selecting 'rename' from the menu. Two files? Painful but doable. Three files? Oh hell no, I'm switching to my always-open-in-background terminal window, and write a quick
c=1; for f in *.jpeg; do mv "$f" $c.jpeg; c=`expr $c \+ 1` ; doneand it takes twice less time than clicking things through with mouse.And yes, I wrote that shell command off the top of my head on the first try and without edits.
Just so you know, in emacs you can do mass rename of multiple files using dired-mode. Never use a for loop again.
There's also vidir from moreutils, which lets you bulk-rename files in your $EDITOR of choice.
