  • 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.

    If EXPR is omitted, uses $_ .

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