I am kinda confused with this, am not sure what is happening
i have a script say test.sh
----------
Code:
cat myfile | while read line
do
exit 2
done
echo "out of loop"
-----------
as it is evident, the exit should cause the script to terminate ,hence producing no output for the script.
now when i run the script as "./test.sh", the behaviour is as expected.
but when i run it with nohup as "nohup ./test.sh &", the "out of loop" statement appears in the output, indicating that the exit just gets it outside the loop but does not exit the program.

EXAMPLES
It is frequently desirable to apply to pipelines or lists of commands. This can be done only by placing pipelines and command lists in a
single file, called a shell script. To run the script using
features apply to the entire contents of file. If the shell script file is to be executed often, the need to type can be eliminated by
setting execute permission on file. The script can also be run in the background with interrupts ignored (see sh(1)):
