COMMAND TASK

The Command task allows us to specify one or more shell commands in UNIX or DOS commands in Windows to run during the workflow.

For example, we can specify shell commands in the Command task to delete reject files, copy a file, or archive target files.

Ways of using command task:

1. Standalone Command task: We can use a Command task anywhere in the workflow or worklet to run shell commands.

2. Pre- and post-session shell command: We can call a Command task as the pre- or post-session shell command for a Session task. This is done in COMPONENTS TAB of a session. We can run it in Pre-Session Command or Post Session Success Command or Post Session Failure Command. Select the Value and Type option as we did in Email task.

Example: to copy a file sample.txt from D drive to E.

Command: COPY D:\sample.txt E:\ in windows
