shell - Assigning space to variables in Unix -


suppose if want print 3 variables variables 

var1="123" var2="   " var3="456" echo $var1$var2$var3

the result got executing command 123 456; wanting 3 spaces rather single space.

kindly suggest technique print it.

use double quotes:

echo "$var1$var2$var3"

many problems resolved using double quotes.
