I am writing a shell script for some purpose. I have a variable of the form --

```
var1 = "policy=set policy"

```

Now I need to manipulate the variable var to get the string after index `=`. That is I should have "set policy". Also I need to to this for many other variables where the value of "=" is not constant. Like 

```
var2 = "bgroup = set bgroup port"
var3 = "utm = set security utm" 

```

Can you give me an idea how to do it, please?
