- .SH SYNOPSIS
- \fBpid \fR?\fIfileId\fR?
- .BE

- .SH DESCRIPTION
- .PP
- If the \fIfileId\fR argument is given then it should normally
- refer to a process pipeline created with the \fBopen\fR command.
- In this case the \fBpid\fR 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 \fIfileId\fR refers to an open file
- that isn't a process pipeline.
- If no \fIfileId\fR argument is given then \fBpid\fR returns the process
- identifier of the current process.
- All process identifiers are returned as decimal strings.
-
- .SH KEYWORDS
- file, pipeline, process identifier
