Study about ps aux

The kill command is used in conjunction with a process ID (PID),

The killall command is used in conjunction with command names.

For command names and PIDs, the ps aux comes into use.

name@host:~/$ ps aux
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND

root 231 0.0 0.0 0 0 ? D Apr30 0:16 [jbd2/sda5-8]
root 232 0.0 0.0 0 0 ? S< Apr30 0:00 [ext4-dio-unwrit]

syslog 644 0.0 0.0 28940 1524 ? Sl Apr30 0:05 rsyslogd -c5

Descriptions as below

USER = user owning the process
PID = process ID of the process
%CPU = It is the CPU time used divided by the time the process has been running.
%MEM = ratio of the process’s resident set size to the physical memory on the machine
VSZ = virtual memory usage of entire process
RSS = resident set size, the non-swapped physical memory that a task has used
TTY = controlling tty (terminal)
STAT = multi-character process state
START = starting time or date of the process
TIME = cumulative CPU time
COMMAND = command with all its arguments
