problem with exit while using nohup
Hi,

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.

any ideas on this ?

nohup

NOHUP(1)                                                           User Commands                                                          NOHUP(1)

NAME

       nohup - run a command immune to hangups, with output to a non-tty

SYNOPSIS

       nohup COMMAND [ARG]...
       nohup OPTION

DESCRIPTION

       Run COMMAND, ignoring hangup signals.

       --help display this help and exit

       --version
              output version information and exit

       If  standard  input  is a terminal, redirect it from an unreadable file.  If standard output is a terminal, append output to 'nohup.out' if
       possible, '$HOME/nohup.out' otherwise.  If standard error is a terminal, redirect it to standard output.   To  save  output  to  FILE,  use
       'nohup COMMAND > FILE'.

       NOTE: your shell may have its own version of nohup, which usually supersedes the version described here.  Please refer to your shell's doc-
       umentation for details about the options it supports.
