In the following example:
-rw-rw-r-- 1 rks rks 28422 Jun 15 18:05 smog
-rw-rw-r-- 1 rks rks 28422 Jun 15 18:05 smog
---
|
these 3 places indicate what the OWNER can do; in this case, read and write
-rw-rw-r-- 1 rks rks 28422 Jun 15 18:05 smog
---
|
these 3 indicate what group owners can do; in this case read and write
-rw-rw-r-- 1 rks rks 28422 Jun 15 18:05 smog
---
|
and these indicate what ordinary users can do; in this case read only.
Just remember two things:
4=read, 2=write and 1=execute and
three numbers (664, for example) represent owner, group and user permissions;
digit 1 for owner permissions, 2 for group, and 3 for ordinary user permissions.
You can see that 664 would indicate
(421421421)
-rw-rw-r-- 1 rks rks 28422 Jun 15 18:05 smog
|||
6 for owner (read+write,)
-rw-rw-r-- 1 rks rks 28422 Jun 15 18:05 smog
|||
6 for group (read+write,)
-rw-rw-r-- 1 rks rks 28422 Jun 15 18:05 smog
|||
and 4 for ordinary users (read.)
Now, say I don't want users to be able to read this file. I do:
$ chmod 660
which as you know, means read/write permission for owner and group; no permission
for ordinary users.
This results in:
-rw-rw---- 1 rks rks 28422 Jun 15 18:05 smog
So you can see that now, only rks and members of group rks can read and write this
file.
(You could have also used
$ chmod u-r
to change the permissions.)(o = owner, g = group, u = user; r = read, w = write, x =
execute)
