Jim has already given you the answer, so just some extra
information... You may not be aware of this, but you can get a listing
of ALL Perl functions, ordered by category, by typing this at your
command prompt:

perldoc perlfunc

If you do that, you will see, for example:
Functions for SCALARs or strings
"chomp", "chop", "chr", "crypt", "hex", "index", "lc",
"lcfirst", "length", "oct", "ord", "pack", "q/STRING/",
"qq/STRING/", "reverse", "rindex", "sprintf", "substr",
"tr///", "uc", "ucfirst", "y///"

Perhaps not the most helpful in this case, as it may not be intuitive
that "lc" stands for "lowercase", but it's still good to know in
general.

Your answer is short and to the subject, but not all perl programmers use
Linux. I can mention only that some of us are using ActiveState Perl and we
have not any perldoc.exe on our Windows PCs :-)
Maybe will be better to write some "OS independent", e.g. "look at function
uc()".
I don't know what type of documentation is on Mac.

Yes, we do. I'm on Windows Vista, and it works for me. Even if it
didn't, so what? I can always go to perldoc.perl.org and do a search for
uc and lc.

The answer Jim Gibson gave is fine, even for those of us on Windows.

We have perldoc.bat on our system in the \perl\bin directory.
And we have also the HTML documentation under \perl\html.
Simply open the index.html, in the left frame search for perlfunc, klick
it and search for upper.

I think the same as on Win. or Unix: perldoc and/or the HTML documentation.

C:\DOCUME~1\asu1\LOCALS~1\Temp> perldoc -f uc
uc EXPR
uc
Returns an uppercased version of EXPR. This is the internal
function implementing the "\U" escape in double-quoted strings.
Respects current LC_CTYPE locale if "use locale" in force. See
perllocale and perlunicode for more details about locale and
Unicode support. It does not attempt to do titlecase mapping on
initial letters. See "ucfirst" for that.

If EXPR is omitted, uses $_.
