To be specific: Tru64 and Linux both process ps commandline arguments
this way.
Linux: Unix options may be grouped and must be preceeded by a dash.
BSD options may be grouped and must not be used with a dash.
GNU long options are preceeded by two dashes.
Tru64:
ps [-aAdejflm] [-o specifier] [=header] ,... [-O specifier] [=header]
,... [-g glist] [-G glist] [-p plist] [-s slist] [-t tlist] [-u
ulist] [-U ulist] [-n nlist]
[Tru64 UNIX] The following BSD compatible options can be used with
ps (note that these options are not prefixed with a - (dash)
character):
ps [aAeghjlLmsSTuvwx] [o specifier] [=header] ,... [O specifier]
,... [=header] [t tty] [process_number]
