    I looked at two interesting issues today around the ps program in the procps project. One had a solution and the other I’m puzzled about.

    Issue #9 was quite the puzzle. The output of ps changed depending if a different option had a hyphen before it or not.

    First, the expected output

    $ ps p $$ -o pid=pid,comm=comm
 pid comm
31612 bash

    Next, the unusual output.

    $ ps -p $$ -o pid=pid,comm=comm
pid,comm=comm
 31612
