# NAME

ucfirst - return a string with just the next letter in upper case

# SYNOPSIS

ucfirst EXPR

ucfirst

# DESCRIPTION

Returns the value of EXPR with the first character in uppercase (titlecase in Unicode). This is the internal function implementing the `\u` escape in double-quoted strings. Respects current LC_CTYPE locale if `use locale` in force. See the perllocale manpage and the perlunicode manpage for more details about locale and Unicode support.

If EXPR is omitted, uses `$_`.
