Catching the termination of one script

Shell Programming and Scripting
1

Hi
I have a Shell script that needs to execute a command at the
End of the excursion of other script And I cant get a handel
On the trap command. And that is if the trap command
Is the proper way to go

this is a extract of the script

MYHOST=`hostname| cut -d. -f1`
echo $MYHOST

   cd /var/powerpassword/v3.4/ppsparc_solarisV-3.4.15-1/install
exec  ./ppinstall -b $MYMASTER  $MYHOST ;
#
########################################################
# Trap the successfull completion of ppinstal
########################################################
trap ppinstall 0
ppinstall()
{
  echo "Caught Signal ... ."
  ppadmin trace > /var/tmp/`hostname`-trace-result.txt
  echo "Done  ... quitting."
  exit 1
}

The 'exec' command means 'replace the shell with the command I give here'. After you run 'exec ./ppinstall' your shell no longer exists and can't trap anything. :slight_smile: Remove the exec and you won't need trap at all, since the shell script will continue running after ppinstall completes.

Yes thank you

     IJust dicovered that also. Now I have a nwe issue whit the same script

A loop that has issue :frowning:

MYVER=`uname -a | awk '{print $3}'`
   echo  $MYVER
{
   if  ["$MYVER" = "5.10"]
then
      /usr/sbin/svcadm disable telnet
else 
  /usr/sbin/ppadmin stop
}

Please put code in code tags. [ code ] stuff [ /code ] without the extra spaces in the tags.

MYVER=`uname -a | awk '{print $3}'`
   echo  $MYVER
{
   if  ["$MYVER" = "5.10"]
then
      /usr/sbin/svcadm disable telnet
else 
  /usr/sbin/ppadmin stop
}

What are the { } brackets for? This doesn't look like a function. Did you want to do something like this?

MYVER=`uname -a | awk '{print $3}'`
   echo  $MYVER

if  ["$MYVER" = "5.10"]
then
      /usr/sbin/svcadm disable telnet
else 
      /usr/sbin/ppadmin stop
fi
