Howto run a script as root

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.

sudo script

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

---

thanks, the script is running.

Code:

---

./filename

---

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

Code:

---

filename

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

you mean
rm -f ?

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
