xombboxer · 07-18-2011, 04:50 AM

Hi,

I have been running tar command to extract file using root user, but now i have to do this from non root user.
i just came to know about sudo, but i dont know how to use that.
i read this post about sudo and tar error.

what i know about sudo:

to run sudo command i have to make non root user sudo compatible.

use sudo prefix before the commnad like

Code:

sudo <commnad>

now i am a sud'ed user i am running the command with sudo prefix. but still i am getting this error

tar: Error exit delayed from previous errors

can anybody tell where am i going wrong?

Any system admin related command will require super user's (su) or in other words root's permissions.

For example:

sudo /sbin/ifup eth0

would bring up the network interface.

But you will be prompted for a valid password. Prefixing "sudo " will not work unless you add an entry to visudoers file by issuing the command:

Code:

visudo

Example:

Code:

[test@server ~]$ sudo /sbin/ifconfig

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these two things:

        #1) Respect the privacy of others.
        #2) Think before you type.

Password:
test is not in the sudoers file.  This incident will be reported.
[test@server ~]$

Learn about sudoers file and visudo command. How to use "sudo" is already explained.

if you do ls -l u will find files with different color. what each color denotes, for example symlink shows in some color
