Grep = Global Regular Expression Print

It's a text search utility like DOS's 'find', but far more powerful. 
For example:

% grep "\<__dpmi.*(.*)" .../*.c

finds all references to functions that start with the string "__dpmi" in
all .c files in the current directory and all its subdirectories.  Try
that with DOS find.  :)
