OpenBSD 5.3 i386
I have an rc.d(8) script to manage a python server that seems to start
up fine but doesn't manage to successfully match a running process or
stop it because (I think) it's not matching $pexp during script
execution. It does seem to match when testing manually from shell.
$ sudo /etc/rc.d/gunicorn start
gunicorn(ok)
$ ps auxwww | grep gun[i]

## emulate rc_check() in /etc/rc.d/rc.subr:

$ pgrep -fl "^${pexp}"

$ pkill -f "^${pexp}"
$ pgrep -fl "^${pexp}"
$
There's a comment I didn't understand in pkill(1):
If any pattern operands are specified, they are used as regular
expressions to match the command name or, if -f is specified, the full
argument list of each process. However, presently OpenBSD will only keep
track of the first 16 characters of the command name for each process.
Attempts to match any characters after the first 16 of a command name
will silently fail.
Not sure if the 16 character limit applies with what I'm seeing but
I'm supposing not since the operations work manually from the shell.
I think the only modification I should have to make is the setting for
pexp to match the nonstandard process name and it shouldn't require
overriding any rc_* functions. What am I botching?
