3.2.92 mkdir





This function creates the directory specified by FILENAME , with permissions specified by the numeric MODE (as modified by the current umask). If it succeeds it returns 1, otherwise it returns 0 and sets $! (from the value of errno ).

If mkdir (2) is not built in to your C library, Perl emulates it by calling the mkdir (1) program. If you are creating a long list of directories on such a system it will be more efficient to call the mkdir program yourself with the list of directories to avoid starting zillions of subprocesses.
