join
  • join EXPR,LIST

    Joins the separate strings of LIST into a single string with fields separated by the value of EXPR, and returns that new string. Example:

        $rec = join(':', $login,$passwd,$uid,$gid,$gcos,$home,$shell);

    Beware that unlike split, join doesn't take a pattern as its first argument. Compare "split".
