Running in the Foreground
To run a Python script (for example, download.py) in Linux, execute it directly in the command line
python download.pyThis runs in the foreground, and if the foreground is closed, the program will be interrupted, which is quite inconvenient.
Methods for Running in the Background
nohup python -u download.py > output.log 2>&1 &nohup: This stands for no hang up, meaning it will run continuously without being interrupted;
python: Indicates the version of the Python interpreter to be used;
-u: Runs Python in unbuffered mode, meaning the output is flushed immediately rather than being cached and output together;
download.py: The name of the Python code file to be executed;
>: Redirects standard output;
output.log: Specifies the name of the log file;
2>&1: Redirects standard error output to the same location as standard output;
&: Causes the command to run in the background
