There is the problem, and my information was incorrect.
Freebsd 4.11 returns this with the command string: ps -ax -ww -o pid,ppid,user,start,state,pri,pcpu,cputime,pmem,rss,vsz,args ps: args: keyword not found PID PPID USER STARTED STAT PRI %CPU TIME %MEM RSS VSZ 0 0 root 31Aug05 DLs -18 0.0 0:04.53 0.0 0 0
Freebsd 6.1 returns: (as expected) ps -ax -ww -o pid,ppid,user,start,state,pri,pcpu,cputime,pmem,rss,vsz,args PID PPID USER STARTED STAT PRI %CPU TIME %MEM RSS VSZ COMMAND 0 0 root 17Jun06 WLs 98 0.0 0:00.00 0.0 0 0 [swapper]
So, my subject line was wrong, the PS line works fine in v6.1, its v4.11 it breaks in.
Excerpt from #man ps:

So, I go looking... Can't find where PS is told to do this!!! Argh.
A bit of guidance, like what file tells PS to read those columns? and why does it hate the COMMAND column?The "ps" command that the Hobbit client runs is in the ~hobbit/client/hobbitclient-freebssd.sh script. It was recently changed to provide a specific set of columns and therefore now is
ps -ax -ww -o pid,ppid,user,start,state,pri,pcpu,cputime,pmem,rss,vsz,args
Last I tested this, it did provide the "COMMAND" column. Maybe this has changed in 6.1 ?
