Execute commands on remote server behind another server (jumphost) using Plink

I am trying to make an automation using Power Automate Desktop for PuTTY. I have come across a solution to use cmd to run commands using plink. I used the following steps:

1. I added PuTTY to system variables

2. I used the command (in cmd):

   plink -ssh hostname@ipaddress -pw password -no-antispoof -m C:\commands.txt
   

3. I edited command.txt:

   ssh anotherIP -pw passwordForAnotherIP
   cd /tmp
   cat filename
   

When I run the command in cmd, I can not input password for the other server that needs to be accessed inside the first one. The error shown is

Bad Port 'w'

The server runs bash 4.2. How can I input password inside the txt file commands so that command line plink command takes it?

Better solution is using Plink's -proxycmd:

plink -ssh anotherIP -pw passwordForAnotherIP -no-antispoof -proxycmd "plink -ssh hostname@ipaddress -pw password -nc anotherIP:22" -m C:\commands.txt

With the commands.txt containing only the:

cd /tmp
cat filename

To answer your literal question:

The OpenSSH ssh has no -pw switch. See Automatically enter SSH password with script.

Additionally, your command.txt won't do what you think anyway. It won't run the cd and cat within the ssh. It would run them after the ssh. So on the ipaddress. How to do this properly is discussed in: Entering password to remote ssh through Plink after establishing a connection.
