OT: Need some shell scripting hints

Guy,

This calls for another Useless Use of Cat award, and you get extra
points for not just spawning a single useless process, but one for
every file found by "find".

You better hope you don't have a directory ending with ".txt" :)

Since Perl can take the list of file names as parameters and they will
appear in the magic <>, why not just

	find . -type f -name '*.txt' | xargs perl -ne 'qx(something $_);'

Or why not just avoid the unnecessary piping and xargs and use backticks:

	perl -ne 'qx(something $_);' `find . -type f -name '*.txt'`
