Kibana Unable to find the process running

I have started Kibana using nohup ./kibana & but unable to find the same nohup using ps -ef | grep kibana

However I do see the nohup.out file is being populated.

Trying to reproduce this. Can you share your Kibana version? Here's my output:

~/Downloads/kibana-7.13.2-SNAPSHOT-linux-x86_64/bin » nohup ./kibana &  jon@xps
[1] 13719
nohup: ignoring input and appending output to 'nohup.out'
