Thread: Ubuntu Linux folder permissions

hi,
i need to give read and write permission on specific folder for specific user.else that user can,t do anything on the server.help me out

thanks

To set permission use chmod command - Unix or Linux commands for changing user rights

To change folder / file permission use chown command - How to use chmod and chown command

Hi,

you can use the 'setfacl' command to achieve this.


eg:

[root@ldp tmp]# touch sample.txt
[root@ldp tmp]# getfacl sample.txt #list current ACL
# file: sample.txt
# owner: root
# group: root
user::rw-
group::r--
other::r--

[root@ldp tmp]# chmod 700 sample.txt
[root@ldp tmp]# getfacl sample.txt
# file: sample.txt
# owner: root
# group: root
user::rwx
group::---
other::---

[root@ldp tmp]# setfacl -m u:aneesh:rw sample.txt # give the read,write access to user aneesh

[root@ldp tmp]# getfacl sample.txt
# file: sample.txt
# owner: root
# group: root
user::rwx
user:aneesh:rw-
group::---
mask::rw-
other::---





By using setfacl command you can add as many users as you like.

The easiest way to do what you want would be to set the folder's owner group to a group in which the user belongs.

Code:

groupadd <group_name>
usermod -a -G <group_name> <username>
chgrp <group_name> <your_folder>

Than you set your folder's group permission like you want (using chmod)
