The bsd "ps" command doesn't take the same flags.  And some linux "ps"s will
guess bsd or sysv depending on whether the options are preceeded with a '-',
but will guess wrong on the above.  Add in vendor extensions and GNU
extensions and random other compatibility hacks, and it's pretty out of
control.
