Re: Checking for directory write permissions

Just use

if( not -w $dir) {
    die "directory $dir not writeable.\n";
}
[download]

The test -w works for files and directories. See perlfunc, -X (file tests).

_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /
----------------------------  \__(m.====·.(_("always off the crowd"))."·
");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}

Warning. The -w option will give you a misleading postive result in the case where you have permissions, but the partition is mounted read-only (popular for NFS on unix). We actually just wrote a quick function to test writeability by opening a file for write access wherever we were checking, and, if successful, deleting it afterwards. It was the only foolproof way we could come up with of detecting the situation.	[reply]
