сообщить снимок текущих процессов (report a snapshot of the current processes.)
Описание (Description)
ps displays information about a selection of the active
processes. If you want a repetitive update of the selection and
the displayed information, use top instead.
This version of ps accepts several kinds of options:
1 UNIX options, which may be grouped and must be preceded by a
dash.
2 BSD options, which may be grouped and must not be used with a
dash.
3 GNU long options, which are preceded by two dashes.
Options of different types may be freely mixed, but conflicts can
appear. There are some synonymous options, which are
functionally identical, due to the many standards and ps
implementations that this ps is compatible with.
Note that ps -aux is distinct from ps aux. The POSIX and UNIX
standards require that ps -aux print all processes owned by a
user named x, as well as printing all processes that would be
selected by the -a option. If the user named x does not exist,
this ps may interpret the command as ps aux instead and print a
warning. This behavior is intended to aid in transitioning old
scripts and habits. It is fragile, subject to change, and thus
should not be relied upon.
By default, ps selects all processes with the same effective user
ID (euid=EUID) as the current user and associated with the same
terminal as the invoker. It displays the process ID (pid=PID),
the terminal associated with the process (tname=TTY), the
cumulated CPU time in [DD-]hh:mm:ss format (time=TIME), and the
executable name (ucmd=CMD). Output is unsorted by default.
The use of BSD-style options will add process state (stat=STAT)
to the default display and show the command args (args=COMMAND)
instead of the executable name. You can override this with the
PS_FORMAT environment variable. The use of BSD-style options
will also change the process selection to include processes on
other terminals (TTYs) that are owned by you; alternately, this
may be described as setting the selection to be the set of all
processes filtered to exclude processes owned by other users or
not on a terminal. These effects are not considered when options
are described as being "identical" below, so -M will be
considered identical to Z and so on.
Except as described below, process selection options are
additive. The default selection is discarded, and then the
selected processes are added to the set of processes to be
displayed. A process will thus be shown if it meets any of the
given selection criteria.
