xargs(1) -- generic solution to taking a list of command arguments from
a file or pipe, and building a command line from them.
So, supposing you have a list of files (one per line) you want to delete
in a file called 'goners':
xargs rm -f < goners
xargs(1) is very commonly used in pipelines with find(1).
Cheers,
Matthew
