in reply to s// All Files In Directory

How can I open all of the file in the directory, and substitute all of the 5s for 6s?

perldoc perlrun yields the answer to your question. Have a look for -pi.

Cheers, Sören

    I'm not too good with the command line (I'm a Windows guy :-). So in what syntax would I use -pi?

      Learn to be good with the command line. Being saddled with Windows is no excuse; if you can't stand the Windows command line (I can't), install Cygwin.

      -p process line-by-line and print the results -i operate on files in place -e execute the following code Hence: perl -p -i -e 's/foo/bar/g' *

        So perl -p -i -e 's/5/6/g' will do what I want?
