[SOLVED] File permissions changed

qazianeel · 01-30-2013, 06:36 AM

Hello friends,

While practicing by mistake I've changed permission of following directories with their sub-directories:

drwxr-xr-x 5 777 root 4096 Jan 30 17:26 bin
drwxrwxrwx 2 oracle dba 12288 Jan 30 17:26 sbin
drwxr-xr-x 22 root root 4096 May 21 2012 var

I've to revert back directories file permission.

Please help.

Regards

Aneel Ahmed

chmod 744 <dirname> to change the permission to rwxr-xr-x

I could see bin file owner has also been changed to 777

If that is not intended, please use chmod root:root bin to change back the ownership to root.

Not sure about sbin having orcale as its owner.

Hope this helps.

This is incorrect. Ownership cannot be changed using chmod, but chown.

@qazianeel:
What command(s) you had invoked? Do not invoke chmod until you specify that what you've done and what changes have made.

thanks that was a typo.

Seeing as your profile says RHEL5, you can use rpm

chown -R root.root /bin
chmod 755 /bin
chown -R root.root /sbin
chmod 755 /sbin
