Thanks to your help i've reached this step:
original data:
01,01368,2010-12-02,09:07:00,Pass
01,01368,2010-12-02,10:54:00,Pass
01,01368,2010-12-02,13:07:04,Pass
01,01368,2010-12-02,18:54:01,Pass
01,01368,2010-12-03,09:02:00,Pass
01,01368,2010-12-03,13:53:00,Pass
01,01368,2010-12-03,16:07:00,Pass
awk -F , '{if ($4 > "09:10:00") print $2 " was late on", $3 " by coming at ",$4}' test | tee DaysLate ; wc -l DaysLate
01368 was late on 2010-12-02 by coming at 10:54:00
01368 was late on 2010-12-02 by coming at 13:07:04
01368 was late on 2010-12-02 by coming at 18:54:01
01368 was late on 2010-12-03 by coming at 13:53:00
01368 was late on 2010-12-03 by coming at 16:07:00
5 DaysLate
the only thing missing is to find a way to just take the earliest time of each day.
in other words the above output should be:
0 DaysLate # as on 12-02 he came in at 09:07 which is before 09:10 and on 12-03 he came in at 09:02 which is also before the set time
