Sample Shell Script with Menu

[Mark Treen_1]

Hi to All

Ok maybe I am going to be chastised to not doing more research but it never hurts to ask I guess.

I need to make a basic script which when run gives the user a list say of ten things whereby they can select a number and then it performs that operation.

Does anybody know where I could find a template script to kick me off. Say something silly with a few options.

Thanks so much in advance!

Cheers

Mark

Hi Mark:

In lieu of declaring '/usr/bin/sh' in the user's initial program field in '/etc/passwd' substitute your shell (menu) script. Then make the script look something like:


#!/usr/bin/sh

PATH=/usr/sbin:/usr/bin:/sbin
trap '' INT QUIT

while true
do
clear
echo "Host: $(hostname). $(date "+%a %x %X %Z"). [ Operations Utilities ]"
echo "\n >>> Enter < 0 > to Logout"
echo "\n >>> Enter < l > to ..."
echo "\n >>> Enter < 2 > to ..."
echo "\n*---> \c"

read CHOICE
case ${CHOICE} in
0 ) exit 0
;;
1 ) ${HOME}/script/abc
;;
2 ) ${HOME}/script/xyz
;;
"") continue
;;
esac
done

exit

Regards!

Mark,

Attached is a template for a menu driven shell script. It can be used as a framework for building upon. Enjoy and hope it helps!!!

I used this in one of my scripts. I hope it helps

}

/usr/bin/perl

write;
print "Enter Choice:";
my $choice=;

if($choice=~/[Aa]) {
print "You picked option A\n";
}elsif{$choice=~/[Ll} {
exit(0);
}

format MENU

Hope this helps

To piggy back off of Mark's question, how do you get a menu driven script to execute a simple command, for example:


echo "\n >>> Enter for the current time"
read choice
case ${choice} in



If the user selects , how would you write this in the script to execute the time command?

Thank all!

>OMGPLSHELP: how do you get a menu driven script to execute a simple command

I was going to say you use the select builtin. And if you look at Pete's example, it does that.

>echo ">>> Enter for the current time"
>read choice
>case ${choice} in

One could do that. For my select example:

echo "Select the compare mode:"
select DT in "-r" "-b" "-a"; do
break
done
if [ "$DT" = "" ]; then
DT="-r"
fi

This prints:
Select the compare mode:
1) -r
2) -b
3) -a
#?

The user types in a number, 1 to 3.
The logic above says if an invalid number is typed, set it to the "-r" choice.

>If the user selects , how would you write this in the script to execute the time command?

For your case:
case ${choice} in
"") date ;;
... # other choices
*) echo "invalid choice: ${choice}" ;;
esac
