The Command Line Interpreter activity allows the user to open a connection via SSH protocol to a server and execute shell commands through this connection. Then it will return the output of the command as a string to UiPath workspace, thus allowing the user to interpret/validate the result.

It is particularly useful when we need to interact with Linux servers from UiPath flows, transmitting the commands to Linux server and then returning the output to UiPath workspace to be interpreted.

The output of the command is interpreted using an [expect-like behavior](https://en.wikipedia.org/wiki/Expect). Therefore the activity will expect a prompt to be matched after each command, returning the output based on this expected prompt.

**Input:**

*    as string, mandatory
*    as string, mandatory
*    as string, mandatory
*    as integer, mandatory
*    as string, mandatory
*    as string, mandatory

**Output:**

*    as string - command result

**Use case 1:** Interaction of the robot with Linux systems, via SSH connections. Send commands to Linux systems, then wait for the prompt and inspect the command output.

This will cover the scope for automation under Linux OS systems.

**Use case 2:** Interaction of the robot with telco equipments (i.e switches, routers) via Command Line Interface if SSH protocol is supported.

This activity allows shell command execution and result retrieving, using SSH
