Example 2: Execute SSH Command Using Environment Variables

The Execute SSH Command can pass values to Environment Variables for use in commands and scripts on the SSH server. When the task executes, the value of the environment variables will be passed to the SSH server before the SSH command is executed. The task supports the use of multiple environment variables.

Environment Variable Names must be defined within the AcceptEnv keyword section of the SSHD_CONFIG file on the SSH Server. When the SSH session is opened, the SSH server passes the accepted environment variable names to

Managed File Transfer

then uses the Environment Variables element to assign a value to the variable.

The following example uses the LC_NAME environment variable to pass in the value of the search attribute in the grep command. When the task executes, the SSH server will search for files that contain the name "kharris" in the /root/Public directory and then write the results to a file.

From within the Project Designer page, navigate to the

Application

Native Calls

folder in the Component Library, and then drag the Execute SSH Command task to the Project Outline.

On the Basic tab of the Execute SSH Command task, specify the SSH Server and Command:

SSH Server: Select a pre-configured SSH server from the drop-down list.
Command: Specify the command to execute on the remote system. Note: The "$LC_NAME" environment variable is used in the command. A value for the LC_NAME variable will be created in step 6 below.

On the Advanced tab, specify where the output of the command will be redirected to:

Redirect Output To: Specify where the standard output from the command, if any, will be directed. By default, the output will be written to the job log.
Output File: Specify the output file path and name of where you want the output written to. This is required when redirecting output to a file.

Click the

Add

button and select the Environment Variable menu item.
