Linux view and end process commands in a detailed

In Ubuntu, terminating a process or terminating a running program is typically done through kill, Killall, Pkill, Xkill, and so on. -------------------------------------------------------------------First look at two examples:  example one: End a program, such as Firefox      type command: Pkill firefox  example Two: End a process, such as find            First Use the PS command to view the PID of the process. Type PS, as shown below: PID TTY time command 285 1 00:00:00-bash 287 3 00:00:00-bash 289 5 00:00:00/sbin/mingetty tty5  290 6 00:00:00/sbin/mingetty tty6 312 3 00:00:00 telnet bbs3 341 4 00:00:00/sbin/mingetty tty4 345 1 00:00:00 Find/-name foxy.jpg 348 1 00:00:00 ps  You can see that the PID corresponding to this process is 345, and now use the KILL command to terminate the process. Type: # Kill 345  again with the PS command to see that the find process has been killed. ---------------------------------------------------------------------------below to learn about the commands:  one, the command to view the process has PS, Pstree , pgrep                                 & nbsp       &NBSP;1, PS                 &NBsp                              show process information, parameters can be omitted  - Aux     show process in BSD style common &NBSP;-EFH     show process  -e in System V style,-A shows all processes  a       &NBS P Show processes for all users on the terminal  x         show no terminal process  u         Show details  f     &NB Sp     Tree display  w         Full display information  l           Show long list   Meaning of the output fields for each column: USER         process owner PID             process id ppid           Parent process%cpu       &NBSP;CPU occupancy%mem       memory usage ni             Process priority.

If you end a single process, use Killkillall < process name >                       &N Bsp      killall and Pkill application methods are similar, but also directly kill the running program, if you want to kill a single process, kill it. Xkill                                                 in the graphical interface to kill the process. When the Xkill is running, the mouse pointer changes to a skeleton pattern, which graphics program crashes a bit and is OK. If you want to terminate the Xkill, press the right button to cancel. For example, when Firefox crashes and cannot exit, Firefox can be killed by clicking the mouse button. Xkill Call Method:
