Automate putty via batch and execute a command

I use putty everyday to login to a Linux session and execute some commands.

Now since I have a thought to automate this process, I would like some help to complete this process.

I have made a batch file which contains the below commands:

Start putty.exe abc@1.1.1.1 22 -pw 1234

Using this script I am able to open a putty session.

Now I want it execute my next command as well:

ps -eaf|grp sometext

Can you please help me to achieve this?

It's a huge challenge for me.
