Hello!!

Am trying to substitute the value of a shell variable with the value of another shell variable. The values are obtained into the shell variables through some other processing.
for ex.
Quote:
var1=regno
var2=usn

i've used the follow sed command..
Code:
sed "s/$var1/$var2/g"

i've also tried the other alternatives i found searching the threads. But nothing worked.. .
Please help!
