Re: [SLUG] mkdir

[Matthew Hannigan <mlh@xxxxxxxxxx>]

Grant Street <grants@xxxxxxxxx> gave the answer previously,
	chmod 2755 topdir

which sets the setgid (the 2) and relaxed perms (the 755)
But this didnt fix the existing dirs group ownership.
Also you might want 775 instead of 755.

See below for my take.

not sticky bit, setgid bit (common mistake)

The better couple of  invocations are:

	chmod g+s topdir # set topdir setgid bit so group ownership is preserved

	chgrp -hR SOMEGRP topdir	# repair group of existing files and dirs
	chmod -R g+rwX,o+rX topdir	# to repair permissions for existing files and dirs

I tend to use symbolic rather than octal,
tends to be easier to remember and more precise/accurate.

PS. exercise for the reader , find out what the -h and the capital X do
(they're important!)
