Perl: UPPER CASE -> lower case

[Armitage]

But I can't seem to find it.

 

[Cheetah8799]

yep, easy. once I opened a book...

$big = uc($little);

$little = lc($big);

got it? good. I knew these Perl books would come in handy some day...

 

[Cheetah8799]

oh, and there's more.

This will do the same as the uc() and lc() functions. All chars go up or down.
$big = "\U$little";
$little = "\L$big";

These will do just the first char of the string I think.
$big = "\u$little";
$little = "\l$big";


There's more, but like 2 pages. I'm reading it out of the O'Reilly Perl Cookbook 2nd Edition. Page 29.

Thanks
I've got a perl book ... I did look. If I had known the function was called uc, I would have found it easily. But then, if I already knew it I wouldn't have to look! (I checked the index & TOC for string functions, uppercase, lowercase, toupper, tolower, etc.)

ya, I looked in a generic Perl 21days type book and couldn't find it. The Perl Cookbook has a MUCH nicer index in the back.

I've got O'Reilly "PERL in a nutshell" (an appropriate receptacle I might add.)

Just to be different:

$var =~ y/A-Z/a-z/;

I knew there must be some regex-ish way to do this as well, but missed it also.
