-A Select all processes. Identical to -e.
a Lift the BSD-style
"only yourself"
restriction,
which
is imposed upon the
set
of all
processes when some BSD-style (without
"-"
) options are used or when the
ps
personality
setting is BSD-like. The
set
of processes selected
in
this manner is
in
addition to the
set
of processes selected by other means. An alternate description is that this option causes
ps
to list all processes with a terminal (
tty
), or to list all processes when used together
with the x option
-e Select all processes. Identical to -A.
x Lift the BSD-style
"must have a tty"
restriction,
which
is imposed upon the
set
of all
processes when some BSD-style (without
"-"
) options are used or when the
ps
personality
setting is BSD-like. The
set
of processes selected
in
this manner is
in
addition to the
set
of processes selected by other means. An alternate description is that this option causes
ps
to list all processes owned by you (same EUID as
ps
), or to list all processes when used
together with the a option.
