Need Help??

Description:	This code is very simple, and I think every experienced Perl coder can think of it. However, I use this twice a day, so it's useful to me. It might help out others, or at least make some of you toss away those old `while(1) { print length(<>) - 1, "\n" }` scripts that some people have.
`perl -ple'$_=length'`

Very nice! I thought of a good use for it - checking for spaces on (what should be) blank lines in POD. It inspired me to alter it to: `perl -nle' print $. if length==1'` [download] Thanks Juerd! jeffa L-LL-L--L-LL-L--L-LL-L-- -R--R-RR-R--R-RR-R--R-RR B--B--B--B--B--B--B--B-- H---H---H---H---H---H--- (the triplet paradiddle with high-hat)	[reply] [d/l]

Great idea, but the thing that bites me most is having indents in pieces of code in POD. Between paragraphs, lines should be empty, even when dealing with code. So I changed it to: `perl -nle'/^\s+$/&&print$.'` [download] U28geW91IGNhbiBhbGwgcm90MTMgY W5kIHBhY2soKS4gQnV0IGRvIHlvdS ByZWNvZ25pc2UgQmFzZTY0IHdoZW4 geW91IHNlZSBpdD8gIC0tIEp1ZXJk	[reply] [d/l]
