[Go] Linux skillfully use ctrl-z background run program

Background:

Recently in the implementation of some long-time procedures, always accidentally forgot to enter the ' & ', the end of the terminal is stuck there, it is depressed

A new terminal was always opened in the past.

Today, look at "Bird Brother's Linux private dishes", when the introduction of vim introduced a ctrl-z command can be the current program cut into the background, very useful! But how do you cut it back? Search, see below:

-----------The following is the original
Suppose you find that a program running in the foreground takes a long time, but you need to do something else, you can use CTRL-Z to terminate the program, and then you can see the system prompt:

[1]+ stopped/root/bin/rsync.sh

Then we can schedule the program to execute in the background: (the number behind BG is the job number)

#bg 1

[1]+/root/bin/rsync.sh &

Use the Jobs command to view the tasks that are running:

#jobs

[1]+ running/root/bin/rsync.sh &

If you want to bring it back to the foreground, you can use

#fg 1

/root/bin/rsync.sh

This way, you can only wait for the task to complete on the console.

& Throw instructions into the background to execute

[Ctrl]+z left the foreground task in the background to pause

Jobs view the working status of the background

FG%jobnumber The backstage task to the front desk for processing.

BG%jobnumber put tasks in the background to handle

Kill management tasks in the background

The command runs with CTRL + Z, forcing the current process to turn to the background and stop it.

1. Bring the process back to run (background)

(1) using the command BG

Example:

[email protected]: ~/unp/tcpcliserv$./tcpserv01

* CTRL + Z is used here, SERV01 is a stop state at this time *

[1]+ Stopped./tcpserv01

[email protected]: ~/unp/tcpcliserv$ BG

[1]+./TCPSERV01 & * At this time serv01 run in the background *

[email protected]: ~/unp/tcpcliserv$

(2) If you use CTRL + Z to stop a few programs?

Example:

[email protected]: ~/unp/tcpcliserv$ jobs

[1]-Running./TCPSERV01 &

[2]+ Stopped./tcpcli01 127.0.0.1

[email protected]: ~/unp/tcpcliserv$ BG%1

BASH:BG: Task 1 has been transferred to background * background run *

2. Restore the process to the foreground run

Example:

[email protected]: ~/unp/tcpcliserv$./tcpserv04

[1]+ Stopped./tcpserv04

[email protected]: ~/unp/tcpcliserv$ FG

。 /tcpserv04

Summary:

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

(2) Jobs shows the currently paused process

(3) BG%N enables the nth task to run in the background (with a space before%)

(4) FG%N to enable nth tasks to run in the foreground

The default BG,FG indicates the last process action without%n!
