Are these hex numbers? bc can convert hex to decimal and do hex math.
The hard part is calculating the next value, and here's an example of
doing that.
nextValue=`echo "obase=16; ibase=16; ${lastValue} + 1" | bc`
Then all you need to do is compare whether the next line you read is
equal to nextValue.

Thanks for reading this: I appreciate your time.
I'm trying to do something that should be very easy to do, and yet I
can't remember how to do it, and I'm asking for help.
I have an alpha-numeric, sorted file, that looks like this:
01AA
01AB
01AC
01AE
01AF
.. etc.
I'm trying to remember what BASH utility, script, or command would
flag the missing value (in this case, "01AD"). There are, of course,
any number of ways to program a solution, but I can't remember which
of the BASH utilities will do it. All suggestion welcome, and thanks
in advance.
