in reply to Question regarding options like -i -n -p

I am not sure of what you want exactly, but if you want to get rid of bakcup files, you can do something like this:

$ perl -i.bak -pe 's/ /  /g; END {unlink "*.bak"}' file.txt

This is *nix syntax, but I guess you could have this untested equivalent under Windows:

perl -i.bak -pe "s/ /  /g; END {unlink qq/*.bak/}" file.txt

    I don't remember about (and cannot test (and don't want to bother looking up)) unlink under *nix, but under Windoze it doesn't do wildcards. But this sure works (for Windose):

    >perl -wMstrict -le "unlink glob '*.bak'; "

      Yes, you are right, my mistake. The unlink function does not take wildwards, also not under *nix. So the use of the additional glob function would be necessary to get it to work.
