Xargs is pretty neat. You have to remember that there are different
implementations of it, too, so xargs on Linux would probably be
different than xargs on *BSD (it always is different in my experience).
The differences would mainly be in switches and default behavior.
I use xargs with lots of different utilities, just depending on what I
need to do with whatever files I'm catching. For example, let's say I
wanted to rename some files:
locate *.PDF | xargs -I % mv % `basename % .PDF`.pdf
It's handy if you have a bunch of files in one directory that you want
to check somehow:
ls *.{jpg,gif} | xargs -J % file % | grep -v 'JPEG\|GIF'
Moving files to another directory is a popular use:
locate *.suf | xargs -J % mv % /path/to/dir
Note that you do not always need to use xargs.
locate *.PDF | while read name; do
mv $name ${name%.PDF}.pdf
done
There's lots more you can do with it. Your imagination is almost your
only limitation. :-)
