This is the first time I’ve noticed this:


linux-qfxy:/home/dauddaud # ps aux

Now, I don't have a /USR/SBIN on my system. Nor do I have a CRON ( of
course, I do have /usr/sbin/cron )

Nonetheless, /USR/SBIN/CRON appears to be running.

Is there a logical explanation for this?

Sounds dodgy. For some reason the options to pribt a process tree don't
seem to worrk, but the SysV style ps -ef lists the pid and ppid (parent
process id). to save wading through masses of lines try ps -efp2060 to give
you the ppid of process 2060.

You can backtrack like this to find whence it came (if you're lucky)

If at first you don't succeed - give someone else a go

Thx for the link, Werner. Another fine squabble w/ no resolution ;)

Thx for your response ... I'm on my Debian box at the moment, and that
duly reports /usr/sbin/cron. I'll check later.

In the meantime, cf. Werner Flamme's response ... it appears to be either
a bug or a feature, depending on your viewpoint :)
