Pass return value of a function in background process
Hi,
I have created a function f1 defined in script A.sh .I have called this function in background . But I want to use its return value for another function f2 in script A.sh.
I tried declaring it as a global variable, yet it always returns the status as 0. Is there any way with which I can get the values from function f1 and use it in function f2 with function f1 running in background ??

template of my script:
Code:
STATUS=0; export STATUS

f1()
{
if<>
then
   STATUS=1
else
   STATUS=2
fi
}


f2()
{
f1 >output.txt &
echo "STATUS $STATUS";
}

f2
