Put this into the file 'doit':
<command>| parallel <command> | parallel <command>
<command>| parallel <command> | parallel <command>
<command> | parallel <command>
<command> | parallel <command>
Then run:
cat doit | parallel -kj0 > file
That way you can run the 4 lines in parallel and make sure there is
not two programs writing to 'file' simultaneously (which may end up
mixing output).
