I tried to run FS Crawler in background on Ubuntu 20.04, and I changed the last line of file bin/fscrawler as following:  
exec " **nohup** $JAVA" ${JAVA\_OPTS} -cp "$FS\_CLASSPATH" "fr.pilato.elasticsearch.crawler.fs.cli.FsCrawler" "$@" **"&"**

But it failed with message:  
exe: nohup /bin/java: not found

Does anybody knows if we can run FS Crawler in background?  
Thanks~

Why not running FSCrawler with:

```nohighlight
nohup bin/fscrawler JOB_ NAME &

```

Would that work?
