in thread Command-line arguments to command-line Perl

Thanks for the suggestion, BrowserUk. I wasn't able to get this to work, because perl seemed to think that the argument was meant for it, rather than the script, and I ended up using suhailck's BEGIN() solution, instead.

I do appreciate everyone's time and effort in helping me understand one of Perl's lesser-known functionalities! Thanks, everyone!

    Sorry. I don't often use -s with -e.

    You have to use -- to delineate between switches meant for perl, and those meant for the -e script:

    perl -pi -se's/.*'def'.*''/\t"def"=>"dumper\/$D.def",/g' -- -D=ADCIF C +onfigFile

    Not very practical on the command line, but useful in shell scripts.


    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
