Linux solves nohup: ignoring input and appending output to “nohup. Out” and nohup: ignoring input redirection error to standard output

1. Direct execution document

nohup ./test.sh

Prompt appears:

 Ignore the input and append the output to the "nohup.out"

And input the output result into the default file nohup. Out

2. Redirecting standard output to a file

nohup ./test.sh > a.txt

Prompt appears:

 nohup: Ignore input redirection errors to the standard output

Output the result to the specified file a.txt

3. Redirecting standard error output to a file

nohup ./test.sh > a.txt 2>&1 &

No hint
