Multiple files

[Daniel D Jones <ddjones@riddlemaster.org>]

How does one handle multiple files via most command line utilities?  For
example, suppose you have a handful of perl scripts (*.pl) and you want
to save them in the same directory with a different extension.  The
command

cp *.pl *.bak

complains that you're copying multiple files but the last command isn't
a directory.

Or suppose you have a series of perl scripts which are saved in DOS
line-end format.  The extra ^M on the bang line causes bash not to
recognize the path to perl, and the script to fail.  Sounds like a job
for sed.

sed s/^M// *.pl > *.unix

Again, the file naming criteria doesn't work.  I could write a script
which essentially generates a new command for each file fitting the
naming pattern, or perhaps use find -exec but there's got to be a
straightforward way to do this on the command line.  Doesn't there?
