Terminal Hungup at the time of read
Hi,
There are two scripts. The second script is called from the first one. These will create two processes on unix. In the second script, there is a read statement in the while loop.
Under unexpected conditions, at the time of reading response from the user, if the terminal hungup happens, the subprocess is still running because of the loop. I need to stop the
subprocess if the terminal hungup happens.
I tried using trap , but it didn't work.
Any help will be greatly appreciated ? Looking for quick response.
Thanks,
kk.

service(8) System Manager's Manual service(8)
NAME
service - run a System V init script
SYNOPSIS
service SCRIPT COMMAND [OPTIONS]
service --status-all
service --help | -h | --version
DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
directory set to /.
The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the
invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and
stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start
command.
service --status-all runs all init scripts, in alphabetical order, with the status command.
EXIT CODES
service calls the init script and returns the status returned by it.
FILES
/etc/init.d
The directory containing System V init scripts.
ENVIRONMENT
LANG, TERM
The only environment variables passed to the init scripts.
SEE ALSO
/etc/init.d/skeleton,
update-rc.d(8),
init(8),
invoke-rc.d(8).
