Call a function using nohup

Question

I am trying to call a function using nohup like this:

function1(){
    while true 
    do
        echo \"function1\"
        sleep 1
    done
}
         


        

Answer 1

Yes ! It is possible however tricky, and strictly bash > v2 compatible :

function1(){ local msg=${*:-function1}; echo msg=$msg; }
nohup -- sh -c "$(typeset -f function1); function1 MESSAGE" >nohup.log 2>&1 0

And don't forget "typeset" is bash deprecated in favor of "declare" (though I don't entirely agree with this).
