Run remote command with putty

  • 772

When I do putty -ssh user@host -pw password echo "hi"

I get a network error

But if I do putty -ssh user@host -pw password

An SSH session is successfully opened in a putty terminal. But I just want to run a single command. How do I do this in Putty?

    You might want to use plink (which is shipped with putty) instead of putty for this.

    Quote from the documentation:

    Plink is a command-line connection tool similar to UNIX `ssh'. It is mostly used for automated operations, such as making CVS access a repository on a remote server.

    For your example:

    plink -ssh user@host -pw password echo "hi"

  2. Per the putty manual, there is only -m which can be used to give it a file containing one or more commands to be executed in sequence.

  3. As @GeraldSchneider suggests, PLINK is more suitable, but if you really wanted to use PuTTY this is how you could do it:

    First, you need to set a few things up as follows:

    1. Connect to the remote box via PuTTY, as in your example.
    2. While on the remote box, create a script to echo "hi". Name it hello.sh.
    3. Right-click the PuTTY window caption and select 'Change Settings...".
    4. Type the name my-saved-session and click Save then Cancel.
    5. Exit the session. Open the PuTTY Configuration panel again.
    6. Select your saved my-saved-session session and click Load.
    7. On the left of the 'Category' tree view, click 'SSH'.
    8. In the 'Remote command' box type /hello.sh -o.
    9. Click back on 'Session' and click Save.

    Now you're good to run the command:

    putty -ssh user@host -pw password -load my-saved-session

  4. If you have pterm (which usually ships with putty) AND you have a local ssh command line program, you can do the following

    pterm -e "ssh [user]@[host] /path/to/your/program"

    where /path/to/your/program could also be bash -c "some; shell; code"
