I have configured ssh to a remote server without prompting for a password with the help of public keys...but now i am not able to execute any commands through a script

what i want is a one line script which takes me directly into /var directory after executing it...searched the entire forum but couldnt find a solution to this prob...

i have tried...

ssh username@hostname "cd /var"
ssh username@hostname [cd /var]
ssh username@hostname ; cd /var
ssh username@hostname | cd /var

nothing seems to work :-(

Er, what exactly are you trying to do? And how do you know that the command didn't work? Are you expecting that you will get a prompt after doing the cd to /var? If so, you are mistaken. Try executing this:
You will see that you are indeed on the remote server and in the /var directory. However you aren't specifying any more actions to be carried out, so your ssh command is getting completed and exiting.

Gr8!! now i am getting my commands to execute...didnt know ssh returns back after executing :-) Thanks...
