Shell Programming and Scripting

Hi,

I tried the statement :
read resp || exit 1

But it didn't catch the hungup signal.
Any more ideas please ?

Thanks,
kk.

Sorry, I didn't fully understand your previous post.

You'd want to put something at the top of the script like this:

Code:

trap 'exit 1' 1

I don't know why it isn't doing that now, but this may help...
FYI, the syntax for a trap is:
trap '(what to do)' [signals to trap]
So the example above will tell the script inplicitly to 'exit 1' when it sees the HUP signal go by...

For a list of signals, issue the command:
kill -l
(lowercase L)

There are two separate questions in this posting but I think Roshan is asking this, if I am not mistaken.

step1.sh file looks like this:
------------------
next=step2.sh
this=step1.sh
logfile=mylog.log
.
.
#invoke next script:
. $HOME/bin/$next

# terminate processing if control comes back to this script
# or if $next is not found to execute
es=$?
if [[ $es != 0 ]]; then
print "`date +%T` Error could not start $next or it terminated"\
"abnormally; exit status was $es" >>$logfile
exit 1
else
exit 0
fi

invoke the shell script using . XXXX.ksh(to execute it in the current shell). Give space after the "."
Then you can use
status=$?
if [ $status -eq 0 ]
then
echo "Invoked script is successful"
else
echo "Invoked shell script failed with the status of $status"
fi

have you tried it and is it not working
