What is the difference between nohup and &? I believe many inexperienced people don't know what to do about it. Therefore, this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

1.nohup: uninterrupted operation

Whether or not the output of the nohup command is redirected to the terminal, the output is appended to the nohup.out file in the current directory.

If the nohup.out file in the current directory is not writable, the output is redirected to the $HOME/nohup.out file.

If no file can be created or opened for append, the command specified by the Command parameter is not callable

2. Running in the background

Combination of the two: nohup command &

3. View the background running process:

Ps-ef | grep

Ps-aux | grep

Awk extraction process ID

Ps-aux | grep * * | grep-v grep | awk'{print $2}'

4. View the port:

View the process using a port: lsof-iRanger 6800

Netstat-anp | grep 6800

CentOS7 uses ss-anp | grep
