trying to pass multiple bash commands via groovy and/or call a file

What I am trying to do is ssh to a server, enter the user/password, then sudo, then cd to a directory all via groovy in soapui

I'm able to login to the server using a cmd with:

C:\\Putty\\putty.exe -ssh m123456@xxxxx.xx.xx.com -pw mypassword

but I cant pass in the sudo commands.  I tried

 C:\\Putty\\putty.exe -ssh m123456@xxxxx.xx.xx.com -pw mypassword -m D:\\BASH.txt

OR  C:\\Putty\\putty.exe -ssh m123456@xxxxx.xx.xx.com -pw mypassword  -C 'sudo su - Aoss'

Any clues?
