nohup Cheat Sheet
Usage
nohup <command> &
nohup <command> >/dev/null 2>&1 # to drop all output and avoid nohup.out
Disowning
If the process dies on terminal close despite nohup, use disown
nohup <command> &
disown
You can check wether this is needed using
nohup <command> &
grep SigIgn /proc/$!/status
If the last bit of the SigIgn value bitmask is set then it is fine. Otherwise use disown.
