Personally, I find that odd -- moving from an array of 21 elements to 21 DIFFERENT scalars?! >perl -p -i -e 's/something\[([0-9][0-9]?)\]/SOMETHING$1/g' file > >"file" becomes 0 bytes.

If you want to make a backup, give the -i flag an extension: perl -p -i.bak -e 's/something\[(\d\d?)\]/SOMETHING$1/g' file -- Jeff "japhy" Pinyan [EMAIL PROTECTED] http://www.pobox.com/~japhy/ RPI Acacia brother #734 http://www.perlmonks.org/ http://www.cpan.org/ ** Look for "Regular Expressions in Perl" published by Manning, in 2002 ** <stu> what does y/// stand for? <tenderpuss> why, yansliterate of course. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
