in reply to using stat

check out this documentation

here's an example from it:
Because the mode contains both the file type and its permissions, you +should mask off the file type portion and (s)printf using a "%o" if y +ou want to see the real permissions. $mode = (stat($filename))[2]; printf "Permissions are %04o\n", $mode & 07777;In scalar context, +stat returns a boolean value indicating success or failure, and, if s +uccessful, sets the information associated with the special filehandl +e _. The File::stat module provides a convenient, by-name access mechanism: use File::stat; $sb = stat($filename); printf "File is %s, size is %s, perm %04o, mtime %s\n", $filename, $sb->size, $sb->mode & 07777, scalar localtime $sb->mtime;
