CHMOD on folders - How do I know what the current CHMOD is on a folder? What ones are there? Linux N00b


Ive a linux friend helping me with Samba.
I don’t want to ask him everything.

Chmod will be changed on a few shares.
I would like to compare the CHMODs that are there now before they are changed to see what has been done and better understand.

So how do I know the current CHMOD on a folder?

As I wrote - look at my very first comment!

Anyway, here you go:

First letter "d" - directory
First triplet "rwx" - read/write/scan for owner "root"
Second triplet "rwx" - read/write/scan for group "root"
Third triplet "rwx" - read/write/scan for "all others"

That's the same as "777" or, in the symbolic form "ugo=rwx"

With CHMOD you mean permissions, don't you?

Check permissions of a folder (a "directory" in Linux!) with

ls -ld directoryname

The first 9 characters are the ones you're searching for.

The first one indicates the type (directory (d), regular file (-), link (l) etc).

The next three triplets indicate permissions (r=read, w=write, x=execute/scan) for owner, group, others.

Octal representation is 4=read, 2=write, 1=execute, so

drwxr-xr-x

is actually a directory with octal permissions 755.

Hi what chmod is the most open for a folder - Im setting up a share and only one user on samba can access it.  Two others cant.

The two that cant are listed in " give access to these users"

Which kind of access are you talking about? Read, Write, Execute/Scan?

The most open setting is "rwx", obviously, so the command to give these permissions to  "others" (i.e. users neither owning the directory nor being members of the group owning it) would be:

chmod o+rwx directory

See "man chmod" for details!

chmod 777 foldername

is the most you can get.  It gives total permission for everything  -- not a very good practice though

you can also do

chmod -R 777 folder
would make the least restrictive permissions for the folder and its contents.

Is there a way to see the current permissions or chmod status on a folder?

I have a working example on another server but dont want to change it, but would be interested in copying its permissions on its shares to see the result.

drwxrwxrwx. 18 root root 4096 Mar  8 19:16 users-personal
[ed@server1 users folders]$ ls -ld admin-private
drwxrwxrwx. 5 root root 4096 Mar 15 03:55 admin-private
[ed@server1 users folders]$ ls -ld admin-public
drwxrwxrwx. 2 root public 4096 Mar 14 22:52 admin-public

Not knowing Linux / Samba - I cant tell what mod this is in this example.  
They all appear to be the same mod.
What mod?

Btw. that's the most open setting you can have. Open like a barn door for just everyone.

That was very well explained there!
My pall is not explaining things very well to me!

And thanks to everyone else as well.
