variable=$something       # variable has some characters -- we don't know how many
rest=${variable#???}      # we removed the first 3 characters 
first3=${variable%$rest}  # now we have the first 3 characters

This works as long as the variable has at least 3 characters in it. If it has only one or two, first3 will be empty.
