Install softwares on redhat linux using powershell

After deploying trend micro deep security today, I created new task for my self to install its agent rpm on around 150 linux servers. I am not very good in linux scripting, and thought lets try it from windows powershell. In below script i have used pscp.exe and plink.exe tools to connect to linux server from windows. I have mentioned which fiield in the script you need to edit. Copy script from at the end of this blog.


In the script my notepad contents (ip addresses) are like this.

Commands.txt file contents are as below
Results look like this if you are successful.


You might get error something like below. as first time it will cache linux servers key and store in registry, for this servers you will need to rerun the script, and next time it will be succeeded.

root@ password:

have no guarantee that the server is the computer you
think it is.
The server's rsa2 key fingerprint is:
ssh-rsa 2048 dc2:b4:56:aa:05:9c:a9:b8:4d:af:91:fb
If you trust this host, enter "y" to add the key to
PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the
connection.
Store key in cache? (y/n)
