Common commands for "process" Linux Process Control

1) &

Example: Ping baidu.com &

This is used at the end of a command, you can put this command in the background to execute, but this is also possible because the terminal exit causes the process ye to exit

2) nohup background operation ( recommended )

Example: Ping baidu.com &

This will not affect process execution even if the terminal exits

3) CTRL + Z process paused
Scenario: The CP centos6.6.iso/tmp/will be running for a long time, and the terminal will take up the inability to manipulate the other commands, this time in case of broken nets or anything.

4) Jobs
See how many commands are currently running in the background

5) BG

The ordinal of the command executed (not PID)

6) FG (contrary to BG)

ordinal of the command executed (not PID) If there are multiple commands in the background, you can use FG%jobnumber to bring up the selected command , %jobnumber is the serial number (not the PID) of the command being executed in the background that was found through the jobs command .
