If you use top in batch mode you get a list of all processes:
top -b -n 1 > list_of_processes
Before that, if you want the output sorted by memory usage you can do the following:
top
M (this sorts the output on the screen by memory usage)
W (this writes the sort settings to a configuration file ~/.toprc; this settings are used when you then start top in batch mode as described above)

systemd-cgtop
SYSTEMD-CGTOP(1) systemd-cgtop SYSTEMD-CGTOP(1)
NAME
systemd-cgtop - Show top control groups by their resource usage
SYNOPSIS
systemd-cgtop [OPTIONS...]
DESCRIPTION
systemd-cgtop shows the top control groups of the local Linux control group hierarchy, ordered by their CPU, memory, or disk I/O load. The
display is refreshed in regular intervals (by default every 1s), similar in style to top(1). If systemd-cgtop is not connected to a tty,
only one iteration is performed and no columns headers are printed. This mode is suitable for scripting.
Resource usage is only accounted for control groups in the relevant hierarchy, i.e. CPU usage is only accounted for control groups in the
"cpuacct" hierarchy, memory usage only for those in "memory" and disk I/O usage for those in "blkio". If resource monitoring for these
resources is required, it is recommended to add the CPUAccounting=1, MemoryAccounting=1 and BlockIOAccounting=1 settings in the unit files
in question (See systemd.resource-control(5) for details).
To emphasize this: unless "CPUAccounting=1", "MemoryAccounting=1" and "BlockIOAccounting=1" are enabled for the services in question no
resource accounting will be available for system services and the data shown by systemd-cgtop will be incomplete.
OPTIONS
The following options are understood:
-h, --help
Prints a short help text and exits.
--version
Prints a version string and exits.
-p
Order by control group path name.
-t
Order by number of tasks in control group (i.e. threads and processes).
-c
Order by CPU load.
-m
Order by memory usage.
-i
Order by disk I/O load.
-b, --batch
Run in "batch" mode: do not accept input and run until the iteration limit set with --iterations is exhausted or until killed. This
mode could be useful for sending output from systemd-cgtop to other programs or to a file.
-n, --iterations=
Perform only this many iterations.
-d, --delay=
Specify refresh delay in seconds (or if one of "ms", "us", "min" is specified as unit in this time unit).
--depth=
Maximum control group tree traversal depth. Specifies how deep systemd-cgtop shall traverse the control group hierarchies. If 0 is
specified, only the root group is monitored. For 1, only the first level of control groups is monitored, and so on. Defaults to 3.
KEYS
systemd-cgtop is an interactive tool and may be controlled via user input using the following keys:
h
Shows a short help text.
SPACE
Immediately refresh output.
q
Terminate the program.
p, t, c, m, i
Sort the control groups by path, number of tasks, CPU load, memory usage, or IO load, respectively.
%
Toggle between showing CPU time as time or percentage.
+, -
Increase or decrease refresh delay, respectively.
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
