So you maybe don't need sed and awk. But take a look at ImageMagick for
manipulating images. I know of one person who spent days in Paint Shop
Pro making thumbnails of every image in a directory (over 1000 images).
  That becomes a one-line script in a good shell with the right command
line utilities (ImageMagick).

Basically anything (text editing, image manipulation, whatever) that has
to be done repeatedly in the way to multiple files is more easily done
on the command line than in a GUI (IME).

Sed, awk, ImageMagick, etc., are just a few examples of things you can
use on the command line, not an exhaustive list. So just because the
previous poster was only manipulating text files do not assume that that
is all you can do on the command line.
