无法使linux'exec'命令正常工作

Question

I want to use the exec command to run a python script in the background of the current terminal session. Other posts suggest that

exec python myscript.py &

should run the script in the background. However the output of the program is still on my command line. Have I misunderstood the exec command? I just want to have the output of the script ignored or if this isn't possible, sent to a file.

I can't use nohup because I need to send the SIGHUP signal to my script. Apart from nohup, feel free to suggest other solutions.

Answer 1

如果要在后台运行命令，则可以使用nohup exec python myscript.py & ，文件的输出存储在nohup.out文件中

Answer 2

Running in the background just means you can interact with the current shell, but the stdout (and stderr) of the background process is still connected to the terminal. Redirect it somewhere else if you don't want it:

exec python myscript.py &>/dev/null &

Also, why do you need exec ?
