As an aside, if you have a specific task such as to find the PIDs of
particular (or all) processes, it can be better to use a tool designed
to do just that, rather than doing text processing on general programme
output. If there are more tailored tools (and there are), you may find
you have more better control over the task performed, the process is
more efficient, and the output is more predictable. Just a thought.
