in reply to Search through multiple files and output results to new file
I got a Perl 'grep' using:
perl -n -e'print if /pod2usage/' *
'-n' tells perl to process all the files on the command line, line by line, but not print them. '-p' does the same them but prints them ... useful for altering data, like you might with sed.
'-e' specifies an expression to evaluate on each line. It prints the value of '$_' if '$_' matches the regex, /pod2usage/, i.e., if that string appears anywhere in the line.
I'm running on Linux, command line adjustments for Windows are left as an exercise for the student :-)
