Howto run a script as root

**Hermanh** · 01-26-2003, 02:22 PM

I created a script as root to remove some symlinks and to copy some files instead of them.

The problem is that I am not able to run the script as root.
As user knoppix I am able to run the script, but do not have the rights to remove the symlinks.
I want to save the script on the harddisk, so it will be there all the time.
As soon as I save it on harddisk the ownership seems to change to knoppix:knoppix
I tried as root:

Code:

chown knoppix:knoppix filename

ownership did not change.
I tried as root:
chmod u+x filename
and
chmod +x filename
root could still not run the script, while knoppix can, but does not have enough rights.

What can I do about this?

Another question is: how do I get the answer on the question if knoppix should remove the symlink answered with yes without human interferance.

I think you should issue a

Code:

chown root:root filename

or try (as root):

Code:

# chmod 777 filename

Thanks for those answers. I tried them both.

When I do as root:

Code:

chmod 777 filename

I still can not run the script

When I do as root:

Code:

chown root:root filename

I get:

Code:

chown: changing ownership of 'filename': operation not permitted

Also

Code:

sudo filename

does not work as root or as knoppix.

I've started knoppix with the cheatcode knoppix 2 to stay in textmode.
After the script has run the knoppix-box will function as ftp-server.

maybe put
sudo su
at the top of the script
or put
sudo rm / sudo ln etc

what kind of script? and you are running ./script.sh ?
what happens with
sudo ./script.sh ?

When I do as root:

Code:

cp /mnt/hda1/filename /etc/filename

the onwnership of the new file is root:root.
Still I can not run the script as root, not even when I do as root:

Code:

chmod u+x filename

or

Code:

chmod +x filename

or

Code:

chmod 777 filename

Which should work according to several Linux howto's.

I get a message:

Code:

bash: filename: command not found

The file exists
When I do:

Code:

ls -l filename

I get

Code:

-rwxrwxrwx    1  root root   549 jan 26 15:25 filename

('filename' is colored green)
Is user knoppix using another shell or something like that?

you have to do

Code:

./filename

not just

Code:

filename

**Hermanh** · 01-26-2003, 04:02 PM

thanks, the script is running.

Code:

./filename

did do it. I did not expect that because it runned as knoppix using just

Code:

filename

Another question is: how do I get the answer on the question if knoppix should remove the symlink answered with yes without human interferance.

Has one of you also the answer for the second part of my question?

I'm going from memory, but I saw a post either on this forum or on the linuxtag knoppix forum about a user that could not run scripts. IIRC he had to:

/bin/bash script
