The command task is used to execute shell scripts or standalone shell commands. You can define one or more commands or scripts in a command task. If you define multiple command or scripts in the same command task, the task executes the commands in a sequence.
You can define Unix/Perl commands for Unix servers or DOS commands for Windows servers. If your Informatica server is installed on a Unix operating system, you will be able to execute Unix commands. If the Informatica server is installed on Windows, you can use DOS commands.

Add a new command by clicking on the Add a new Command option, as shown in the preceding screenshot. In the Name column, enter the name of the command. For our reference, we are using
COPY_FILEas the command name. - Click on the edit button to open Command Editor and write the command that you wish to execute. If you wish to execute Unix scripts, write the Unix script's path and name, otherwise simply define the Unix command. Click on OK to close the edit view.
