RE: (2) elementary hash (uninitialized value...)

Hmmm... responds with "Use of uninitialized value at line while (<>) {". The .bak file is created, but the original is left as a zero-byte file.

Perl 5.005.03

I dumped the -p switch and put an explicit print statement in and that worked...but it seems like the -p _ought_ to work. I _think_ it doesn't, though, because the Camel book says -p puts an assumed loop around the script with a print in the equivalent of a continue block, so the print would only be seen once. Now, if you remove the while loop and just do this: `#!/usr/bin/perl -p -i.bak my $kill = "what\|ever"; s/$kill//go; s/^\s+//g;` [download] I believe it'll work..it's weird, but it works.
