Permissions in One Shot

[Rami Al-Lolah]

Anyone can tell, how can I apply a specific permission code on all the files, and the subdirectories found under a specific folder.

I want any information found under that specific directory to be inherited with the new permissions.

chmod -R 700. The -R will will get all recursive directories.

Hi Rami,

chmod -R 750 directory_name

Would change the permissions to rwxr-x---
for directory name and everything under it.


you can use more intuitive options like
u for user permission
g for group permissions
o for everyone else

chmod -R u=rwx directory_name

Hi,

chmod -R 644 or 755 or which permission needed.

Hi,

I believe you're looking at the command:

chmod -R perms pathname

e.g.

chmod -R ug+r,o-r,a+X /tmp/robin

Rgds, Robin.

Hi,

chmod, chgrp and chown all have a -R' option for recursivity on subdirectories. Just notice that access rights on a directory is not the same as on a file :

for example :

- write on a file allows you to change its content
- write on directory allows you to change its content also, but in this case it means adding ou removing files.
So you can easily be able to have permission to delete files that you can't even read ...

Regards,

Jean-Louis.

chmod -R /dir

4-read(r)
2-write(w)
1-execute(x)

Ex.
chmod -R 755 /home
This will be as
-rwx-r-xr-x

Thanks

Thank you all, such a quick response is unbelievable.

I figured out what is the correct command through the man pages right after I posted the question.

When I came back to share what I found 'chmod -R go-w *' I saw a huge number of replies.... Thanks anyway

If you want these permissions to remain permanent, (i.e. when new files are created by the users), you'll need to set the 'umask' command in the user's .profile, .cshrc or .login file. If you want global permission control, set 'umask' in /etc/profile or /etc/csh.login, depending on the user's shell.
