cd "no permission"

[Sanjiv Sharma_1]

Env: HP-UX 11.11

I have a user "a" and user "b". Both belong to a group "c".

I have a folder "item" with the following permission
drwxrw---- 2 a c 96 Aug 10 15:47 item

As a user "b", I am unable to do
$ cd item
no permission

When I give the permission 770 then it works.
drwxrwx--- 2 a c 96 Aug 10 15:47 item

Mean as a user "b", I am able to do
$ cd item

Why does it required an execute permission for group "c" to just "cd" by user "b" to the folder owned by "a"?

[Mark Grant]

Because in order to "cd" to a directory, the user has to be able to search it. "x" means search.

The second component of the 9 letter permission code is for users of the same group.

b is of same group but you need an execute permission to enter into an directory.

Hi,

For a user to cd to a directory exeecute permission is required. Here as it is a user of same group you need to have it for same group.

HTH,

permissions on a directory have different meanings to permissions on a file.
Essentially, setting "x" on a file means that the file can be run or executed, while setting "x" on a directory means it allows you to search the directory, or go into it using "cd dirname".

man chmod
