Command Execution › Run SSH Command Operator › Example

Example

This example explains how the Run SSH Command operator operates interactively.

Follow these steps::

1. Open an SSH connection to the remote host.
2. Log in non-interactively using one of the following:
   • A user name and password.
   • A user name and private key.
   • A user name, private key, and passphrase, if the private key was created with a passphrase.
3. Read from the SSH session until one of the following occurs:
   • You match the pattern specified in User Command Prompt. Continue to step 4.
   • The Time to Wait for Prompts expires without matching the pattern specified in User Command Prompt. Fail the operator.
4. Determine whether the operator is set to Run Commands as Another User.
   • If so, go to step 5.
   • If not, go to step 6.
5. Send the Switch User Command and read from the SSH session until one of the following occurs:
   • You match the pattern specified in Switch User Password Text Prompt, which requires a password to switch users.
     • Send the Switch User Password.
     • Read from the SSH session until one of the following occurs:

       – You match the pattern specified in Switch User Command Prompt. Continue to step 6.

       – The Time to Wait for Prompts expires without matching the Switch User Command Prompt. Fail the operator.

   • You match the pattern specified in Switch User Command Prompt, which requires no password to switch users. Continue to step 6.
   • The Time to Wait for Prompts expires without matching the Switch User Password Text Prompt and the Switch User Command Prompt. Fail the operator.
6. The Run SSH Command operator has logged in and switched the user, if applicable. The operator is now ready to execute the commands.
7. Loop through the commands, sending one command at a time, and read from the SSH session until one of the following occurs:
   • You match the pattern specified in User Command Prompt, if we did not switch to another user. Repeat step 7 and send the next command.
   • You match the pattern specified in Switch User Command Prompt, if we switched to another user. Repeat step 7 and send the next command.
   • The Time to Wait for Prompts expires without matching the User Command Prompt or the Switch User Command Prompt (whichever is applicable). Fail the operator.
