PS-EF viewing the active process

PS-EF |grep ABC view activity process with "ABC"

PS-EF |grep-v ABC to view activity processes that do not contain ABC

1) PS A shows all the programs under the current terminal, including other users ' programs.

2) ps-a Show All Programs.

3) PS C lists the program, displays the actual instruction name of each program, and does not include the path, parameter or the indication of the resident service.

4) Ps-e The effect of this parameter is the same as specifying the "A" parameter.

5) When listing the program, PS e displays the environment variables used by each program.

6) PS F Displays the tree structure with ASCII characters, expressing the relationship between the programs.

7) ps-h shows the tree structure, indicating the relationship between the programs.

8) Ps-n shows all the programs except the program under the PS Command Terminal.

9) PS s uses the program signal format to display the program status.

PS S when listing programs, including interrupted sub-program data.

One) ps-t< terminal number >

Specify the terminal number and list the status of the program that belongs to the terminal.

PS u

Displays the status of the program in a user-oriented format.

PS X

Show All programs, do not differentiate by terminal.

The most common approach is to Ps-aux, and then use a pipe symbol to direct to grep to find a specific process and then manipulate the specific process.
