Running script with HERE_DOC method in background

Question

I have a script that should be run in background. I must answer a question as soon as I run the bash..How can I do that?

(nohup python script.py lst '<<HERE yes HERE' &)

If you just need a single line of input, `echo yes | nohup python gpvul.py lst &` is simpler. The parentheses are unnecessary even with your current code. — tripleee, Aug 16 '14 at 06:41

The << heredoc is multiline, like

somescript <<EOF &
input
EOF

the heredoc delimiter should be alone on the final line

You can use one line heredoc with <<<, like:

somescript <<<"this coming from stdin" &

Technically `<<<` is a "here string". It's a Bash extension, so not POSIX portable. – tripleee Aug 16 '14 at 06:39
