But you can use regular expressions instead of goofy shell
matching. Find and ls give you lists of file names and grep
prunes them for you. Shell command substitution then puts
them in the right place in the command, or use xargs when
appropriate. I don't claim that globbing is a horrible evil,
merely that it is an unnecessary evil.
