When you write "-e -MCwd", you're actually asking the perl interpreter to run the Perl code "-MCwd", which results in.. nothing. "-" is used for negation, and that line of "code" is basically negating "MCwd". If you were to add strictures, you would get a warning. $ perl -Mstrict -W -e -MCwd Useless use of negation (-) in void context at -e line 1. The reason this gets you a warning is because you're not doing anything with the value you got from the operation. If you were to use it, the warning would cease. $ perl -Mstrict -W -e "print -MCwd" -MCwd The value of negating MCwd is .. -MCwd. :)
