Are you attempting to stop other users from seeing sensitive things in ps listings? If so, curtailing ps won't stop them, there are other ways to obtain the commandline of a process.

tv_sort
TV_SORT(1p) User Contributed Perl Documentation TV_SORT(1p)
NAME
tv_sort - Sort XMLTV listings files by date, and add stop times.
SYNOPSIS
tv_sort [--help] [--by-channel] [--output FILE] [FILE...]
DESCRIPTION
Read XMLTV data and write out the same data sorted in date order. Where stop times of programmes are missing, guess them from the start
time of the next programme on the same channel. For the last programme of a channel, no stop time can be added.
Tv_sort also performs some sanity checks such as making sure no two programmes on the same channel overlap.
--output FILE write to FILE rather than standard output
--by-channel sort first by channel id, then by date within each
channel.
--duplicate-error If the input contains the same programme more than once,
consider this as an error. Default is to silently
ignore duplicate entries.
The time sorting is by start time, then by stop time. Without --by-channel, if start times and stop times are equal then two programmes
are sorted by internal channel id. With --by-channel, channel id is compared first and then times.
You can think of tv_sort as converting XMLTV data into a canonical form, useful for diffing two files.
EXAMPLES
At a typical Unix shell or Windows command prompt:
tv_sort <in.xml >out.xml
tv_sort in.xml --output out.xml
These are different ways of saying the same thing.
