I just looked at this, and I get the same error just by running

    ps -o pid tty s args

which is effectively what's getting run above.  I believe that -o
requires *one* argument, with either space or comma separated fields:

    ps -o 'pid tty s args'

or

    ps -o pid,tty,s,args

both of which succeed, and print out a perfectly decent process listing.

I would guess that the double single quotes that Philippe is using
should probably be single quotes escaped by backslashes, or double
quotes, or just using commas to separate them.

My version of ps, on Linux, is 2.0.10.
