Hello cmccabe,

Could you please try following and let me know if this helps you.
Let's say we have following Input_file:
Code:
cat Input_file
RETT-01
RETT-03
RETT-11
RETT-13
RETT-33
RETT-34
RETT-34

Then following is the code for same.
Code:
awk -F"-" 'NR==1{print;val=$2;next} ($2-val>1){while($2-val>1){val++;printf("%s%02d\n",$1 FS, val);};print;val=$2;next} {val=$2;print}'  Input_file

Hello Scrutinizer,

Sorry my code looks very similar to you but I was on this page for quite sometime and didn't know you have replied already to it, though mine one of slightly different. Thought to let you know on same.

R. Singh

Time::Seconds(3perl)					 Perl Programmers Reference Guide				      Time::Seconds(3perl)

NAME
Time::Seconds - a simple API to convert seconds to other date values SYNOPSIS
use Time::Piece; use Time::Seconds; my $t = localtime; $t += ONE_DAY; my $t2 = localtime; my $s = $t - $t2; print "Difference is: ", $s->days, " "; DESCRIPTION
This module is part of the Time::Piece distribution. It allows the user to find out the number of minutes, hours, days, weeks or years in a given number of seconds. It is returned by Time::Piece when you delta two Time::Piece objects. Time::Seconds also exports the following constants: ONE_DAY ONE_WEEK ONE_HOUR ONE_MINUTE ONE_MONTH ONE_YEAR ONE_FINANCIAL_MONTH LEAP_YEAR NON_LEAP_YEAR Since perl does not (yet?) support constant objects, these constants are in seconds only, so you cannot, for example, do this: "print ONE_WEEK->minutes;" METHODS
The following methods are available: my $val = Time::Seconds->new(SECONDS) $val->seconds; $val->minutes; $val->hours; $val->days; $val->weeks; $val->months; $val->financial_months; # 30 days $val->years; $val->pretty; # gives English representation of the delta The usual arithmetic (+,-,+=,-=) is also available on the objects. The methods make the assumption that there are 24 hours in a day, 7 days in a week, 365.24225 days in a year and 12 months in a year.

Please see Time::Piece for the license. Bugs Currently the methods aren't as efficient as they could be, for reasons of clarity. This is probably a bad idea. perl v5.14.2 2011-09-19 Time::Seconds(3perl)
