pid(1tcl)
pid --
retrieve process id(s)
Synopsis
pid [fileId]
Description
If the fileId argument is given then it should
normally refer to a process pipeline created with the
open command. In this case the pid
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 fileId refers
to an open file that isn't a process pipeline. If no
fileId argument is given then pid
returns the process identifier of the current process. All
process identifiers are returned as decimal strings.
