said before the computer does a better job of thinking in octal.
So, +t = 1770, right ?
chmod +t ( What number of +t ) /home/edward
Again, that is the case where you already have 770 set, but +t really
means to add the 1000 bit to whatever was there. You can also specify
absolute settings in the symbolic style:
chmod u=rwx,g=rwx,o=t file...
will set 1770 regardless of what is there and is easier to understand.
See 'man chmod' for more details, but it helps to know that the modes
are simply bits where 1 gives the permission, 0 does not. The values
you compute in octal show the combinations of the bits but they really
each only have their own independent meaning so I think the symbolic
form makes more sense.
So... is it correct ?
If you start with
drwx------ /home/edward
the commands
chmod g+rwx /home/edward
chmod +t /home/edward
or
chmod u=rwx,g=rwx,o=t /home/edward
or
chmod 1770 /home/edward
will all give you the same result:
drwxrwx---T /home/edward
So.. only chmod 1770 /home/edward
