my problem was : i was using an variable name (value) ,, which is reserved

)
Solution is :
!/bin/bash

read -p "Please Enter The ip address : " ipnum
find=grep ":@" application.properties
test="connection.url=jdbc

racle:thin:@$ipnum:1521:e"
sed -i "s/"$find"/"$test"/g" application.properties

You mean like using application names like 'find' or 'test'? If you must use these types of names you will find it much safer to capitalise the word so there is no confusion.

Also, no need to go in and out of quotes:

Code:

#current
sed -i "s/"$find"/"$test"/g" application.properties

#alternative
sed -i "s/$find/$test/g" application.properties
