scripting question

Proglem: I'm creating a menu and within the menu one of the options should switch user and ask for a password before executing the next command how would I do this?

Hi Deonicia,

I assume you are using case statement. I would do like this

case $something in

"opt1")
some_commands
;;
"opt2")
echo "Enter the password for user"
su - user1 -c "
command1
command2
command3"
;;
*) echo "invalid choice"
;;
esac

If the option is "opt2", then it will switch user to user1 and then execute the commands enclosed in "". SU itself will ask for the password so you don't have write steps for it.

something like this:

VALID=0
while [ $VALID -ne 1 ]; do

echo "Enter user name to become:\c"
read USERNAME
VALID=`grep -c "^$USERNAME" /etc/passwd`

done

su - $USERNAME


which will switch to the user requested, prompting for the user's password--unless being performed as root or that user.

Hi,
an example of a menu where you have to supply the oracle user's pw for option no. 2, unless you are root:

PS3="Enter item: "
select choice in ls date quit
do
case $REPLY
in
1) ls;;
2) su oracle -c date;;
3|O|q) exit ;;
*) echo "Invalid choice" ;;
esac
done


regards,
John K.

clear
print "Catalyst Script MENU"
PS3="Test Menu, enter choice:"
select clean_menu in "Verify Catalyst Packages" "Set Maintenance Flag on Catalys
t" "Clearing Maintenance Flag on Catalyst" "Reset RF for Deal Instance on Cataly
st" "Reset RF for Main Instance in Catalyst" "Exit"
do
case $clean_menu in
"Verify Catalyst Packages")
/usr/sbin/cmviewcl;;

"Set Maintenance Flag on Catalyst")
/apps/bin/set_cat_maint_mode;;

"Clearing Maintenance Flag on Catalyst")
/apps/bin/clr_cat_maint_mode;;

"Reset RF for Deal Instance on Catalsyst")
echo "Enter the password for user"
su - root;;

an example of the script i'm using and when i choose option 4 it doesn't do anything.

Hi Deoncia,

Couple of problems in your script.

1. Correct the string "catalsyst" in option4.
2. Add option5 and option 6 also like

"Reset RF for Deal Instance on Catalyst")
echo "Enter the password for user"
su - root;;
"Reset RF for Main Instance in Catalyst"
some_function;;
"Exit")
exit;;
esac

done

The text has to match exactly... otherwise it won't work.

Hey Sri,

Thanks for heads up on the typo; however now I'm getting a syntax error on my Exit line. Its saying `) is unexpected.

[Sridhar Bhaskarla]

Looks like you copy-pasted my lines.. That was only to show you the modifications - not to copy them exactly.. Let me try then..

"Reset RF for Deal Instance on Catalyst")
echo "Enter the password for user"
su - root;;
"Reset RF for Main Instance in Catalyst")
some_function;;
"Exit")
exit;;
*)
echo "invalid option";;
esac

done

You will need to fill in "some_function".

Hey Sri,

Thanks for the help thus far, really appreciate it; however, one more question, on option five I need to su to another user id and when I plugged that option in, I'm receiving invalid option.

"Reset RF for Deal Instance on Catalyst")
echo "Enter the password for Deal"
su - deal;;

"Reset RF for Main Instance on Catalyst")
echo "Enter the password for Main"
su - main;;

Can you post the the script from 'select' until 'done' again?. Looks like there are some more mismatches.
