Hi Karthik,

You can try two options,

#1. Try logout, it will logout from script shell.

#2. Create an alias for it, just like "./myscript.sh; exit"

Hi Arun,

Can you give some example how to do

[RAC_1]

To get out of telnet session you need to put in "exit" command.

To disable operation of ^c, you need to set the trap to ignore ^c.
trep '' 3
3 is interrupt signal.

[RAC_1]

dbcheck()
{
if [ $DB123 = "quit" ]
then
clear
break
exit 0
else
getdb
fi
}
logout # logout is quit is entered.

getdb()
{
trap '' 3 # to ignore the ^c
clear
echo "\n\n\n\n\n
Enter the db name you wish to connect to \n or quit to exit : \c"
read DB123

dbcheck
}

getdb

Hi Karthik,

You need to logout from the shell or kill it's PPID within the script. Take a look at the link which i have posted earlier on how to accomplish this.
