lcfirst

See the current Perl documentation for lcfirst.

Here is our local, out-dated (pre-5.6) version:

lcfirst - return a string with just the next letter in lower case

lcfirst EXPR

lcfirst

Returns the value of EXPR with the first character lowercased. This is the internal function implementing the \l escape in double-quoted strings. Respects current LC_CTYPE locale if use locale in force. See the perllocale manpage.

If EXPR is omitted, uses $_.
