In case you are unfamiliar with using Perl directly on the command line the -pi.bak part makes a backup file with a .bak extension before the -e (for execute) executes the 's/this/that/g' on every line of myfile.pl. For a more permanent solution just write a little script like this:

#!/usr/bin/perl -w -i.bak use strict; while (<>) { s/this/that/g; print; }

If you call this script say convert.pl you use it like this:

C:\>type convert.pl #!/usr/bin/perl -w -i.bak use strict; while (<>) { s/this/that/g; print; } C:\>type this.txt this this this this C:\>perl convert.pl this.txt C:\>type this.txt that that that that C:\>type this.txt.bak this this this this C:\>

Just change this and that to whatever you want. For Mac that will be \r and \n respectively.
