delete a file
 

Hi
can someone help me delete a file on a remote server using shell scripting
.

common idea would be to use ssh with the delete command like
If this doesn't suit your scenario, you should explain it further :)

thanx Zirias
it prompts for password , i dont want to have a passwordless ssh login
how can i supply the password with this command
i tried using expect and send command but it doesnt work

Hmm, you'll probably want to use an ssh key. You can generate one for your script, make it have no passphrase and keep it secret by setting appropriate permissions on it.

See ssh-keygen(1).

this will create a ssh login with out password which is not my requirement
i need to somehow pass the password alsong with the ssh command

No it won't, as long as you keep THAT key secret. Passing the password is NOT a good idea, using a key is much more secure.

Hi,

ssh and scp do not have an option to pass the password automatically. That is part of the security mechanism ssh enforces.

As already stated by zirias: Setting up a password-less ssh is the way to go. Much more secure.

Hope this helps.

i did want zirias suggested used the command

ssh [user]@[host] rm -f path/to/file

now it gives me permission denied
the file resides in /home/XYZ/t/txt

Well that probably relates to filesystem permissions. Who is creating the file? Log in the machine interactively, check the permissions with ls -l. You need to add your ssh key to an account that actually HAS permissions for the file you want to delete AND the directory containing that file.

i logged and tried to delete it manually it gives the same permission denied , i checked the ownership group and permission it, owner itself cant delete the file how is this possible..

Hi,
Can you post the output of stat /home/XYZ/t/txt and ls -la /home/XYZ/t/ (as root user).

Hi,

I asked for the output of ls -la /home/XYZ/t/, not ls -la /home/XYZ/t/txt

PS: I'm off-line for a few hours, answer will take a while.

I guess you want to see the permissions of the directory, so, better make this ls -lad /home/XYZ/t :)

thanx solved the directoy had root permissions
