Question

I want to write one shell script like

command1    
ssh vivek@remotehost 
    fire command on remote host

Now I have password in pass.txt . But when I change stdin with file. It is not reading password from file.

script.sh < password.txt 

It is prompting for the password in place of reading password from the file.
What I am doing wrong ?

Second problem is that shell script don’t shows the command fired. Is there a way , I can show fired command from it ?

Note :
I don’t have key based access on remote system. I can only use password based login for ssh.

You can use ssh-agent or expect (the programing language) to do this.
