argument is given then it should normally refer to a process pipeline created with the
command. In this case the
command will return a list whose elements are the process identifiers of all the processes in the pipeline, in order. The list will be empty if
refers to an open file that isn't a process pipeline. If no
argument is given then
returns the process identifier of the current process. All process identifiers are returned as decimal strings.
