Try the internal function uc. To capitalize just the first character, try ucfirst. This has the additional benefit of respecting any locale you have set.

A couple (better?) ways come to mind:

$string = uc($string);
$string =~ tr/a-z/A-Z/;

You can use uc or lc built-in functions to change case. If you wanto to change case of first character only, then use ucfirst or lcfirst functions.

$lower = "name"; $upper = "NAME"; print uc($lower),"\n"; ### This will print : NAME print lc($upper),"\n"; ### This will print : name print ucfirst($lower),"\n"; ## This will print : Name print lcfirst($upper),"\n"; ## This will print : nAME
