ucfirst

  • ucfirst EXPR

  • ucfirst

    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 perllocale and perlunicode for more details about locale and Unicode support.

    If EXPR is omitted, uses $_ .
