The command runs with Ctrl+z, forcing the current process to turn back into the background and stop it.

1. Bring the process back to run (background)

(1) Use the command bg

Example:

zuii@zuii-desktop:~/unp/tcpcliserv$./tcpserv01

* Use ctrl+z here, at this time SERV01 is a stop state *

[1]+ Stopped./tcpserv01

zuii@zuii-desktop:~/unp/tcpcliserv$ BG

[1]+./TCPSERV01 & * At this time SERV01 running in the background *

zuii@zuii-desktop:~/unp/tcpcliserv$

(2) What if you stop a few programs with Ctrl+z?

Example:

zuii@zuii-desktop:~/unp/tcpcliserv$ Jobs

[1]-Running./TCPSERV01 &

[2]+ Stopped./tcpcli01 127.0.0.1

zuii@zuii-desktop:~/unp/tcpcliserv$ BG%1

BASH:BG: Task 1 has been turned into background * background run *

2. Bring the process back to the foreground

Example:

zuii@zuii-desktop:~/unp/tcpcliserv$./tcpserv04

[1]+ Stopped./tcpserv04

zuii@zuii-desktop:~/unp/tcpcliserv$ FG

./tcpserv04

Summarize:

(1) Ctrl+z Stop the process and put it in the background

(2) Jobs displays the currently paused process

(3) BG%N makes the nth task run in the background (there are spaces before%)

(4) FG%N make the nth task run in the foreground

The default BG,FG represents the last process operation without%n!
