Call a function using nohup
nohup applies to commands and not to script functions.
For example, the script (say func.sh) that contains function1() should call the function-:
function1(){ while true do echo "function1" sleep 1 done}function1Now call the script func.sh with nohup in the background-:
nohup ./func.sh &If you need to disable the hangup signal from within the script use the shell built-in trap. The example ignores SIGHUP but can be used to ignore others (e.g. SIGINT).
trap "" HUP # script will ignore HANGUP signal
