Calling multiple commands in a shell script

Question

This is my command.sh[After entering the command nothing happened][2]I want to automate the commands in putty so i have written the commands in a shell script and called it from a batch file

echo -e "password" | sudo -S screen -ls  
pwd 
cd ..

these are the commands in shell script, but the commands pwd, cd are not executing after sudo commands..... No commands are working under sudo commands

How do you execute your script? You wrote batch file, which means a script file windows cmd, was this just a typo? Do the exact same commands work when entered directly in bash? — Socowi

putty.exe -ssh user@hostname -pw password -m myshell.sh -t this is the command in batch file . — swathy mohan

That happens because you launch screen and the process never exits so the bash script cannot move forward to the pwd and cd commands

As a workaround you may write down your commands into the shell script and execute it in screen using

screen -d -m bash ./script.sh
