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.

    If EXPR is omitted, uses $_ .

    This function behaves the same way under various pragma, such as in a locale, as lc does.
