Need a help in a Bash script that performs a select menus task

[black_ice]

hello all .... ,


i want to make a bash script that controls the action of the logs and some services by using menus and i want it to be something like that

starts with that form :

1) mysql
2) system
3) apache
4) quit
Please Select a Choice Or For The Menu :

when the user enter a choice he will redirect to another menu for example if the user type 1 which is for mysql service this menu will appear

1) mysql-log
2) mysql-start
3) mysql-stop
4) mysql-restart


and every choice of that perform a certain function like mysql start , restart , stop and so on

i write this script


#!/bin/bash

#set the PS third variable

PS3='Please Select a Choice Or For The Menu : '

list="mysql system-log apache-log quit"

select i in $list

do

if [ $i = "mysql" ]

then

list2="mysql-log mysql-start mysql-stop mysql-restart"

select j in $list2


do


if [ $j = "mysql-log" ]

then

watch tail /var/log/mysqld.log


elif [ $j = "mysql-start" ]
then
service mysqld start

elif [ $j = "mysql-start" ]

then
service mysqld start

elif [ $j = "mysql-stop" ]
then
service mysqld stop
elif [ $j = "mysql-restart" ]
then
service mysqld restart
elif [ $i= "system-log" ]
then
watch tail /var/log/messages

elif [ $i= "apache-log" ]
then
watch tail /var/log/httpd/error-log


elif [ $i = "quit" ]


then
exit;

fi

done

fi

done



but i got errors >> 1-i cannot choose another option except the choice 1 which is mysql service if i choose another service nothing happened !!!!



Please Select a Choice Or For The Menu : 2
Please Select a Choice Or For The Menu :

I'm no bash expert, but try wrapping your variables in quotes when performing string comparisons (i.e. "$i"). I've had problems in the past.

thanks for you replay but that doesn't work :(

Having tried some later suggestions, break seems to have been the answer

give a look to this one:



#!/bin/bash
OPTIONS="Hello Quit"
select opt in $OPTIONS; do
if [ "$opt" = "Quit" ]; then
echo done
exit
elif [ "$opt" = "Hello" ]; then
echo Hello World
else
clear
echo bad option
fi
done

This is how i might do it...


list2()
{
cat << EOF
1) mysql-log
2) mysql-start
3) mysql-stop
4) mysql-restart
5) Quit to last menu
Please select option:
read choice
while [ 1=1 ];
do
case
...
...
...
esac
done

EOF

}

cat << EOF
1)mysql
2)system-log
3)apache-log
4)quit
Please select a choice:
EOF

while [ 1=1 ];
do
read choice
case $choice in
1) list2;;
2) echo "you chose 2";;
3) echo "you chose 3";;
4) exit;;
*) echo "Not valid"
esac
done
