Shell Programming and Scripting

This is my input file :

Code:

# cat list 20130430121600, cucm, location,76,2 20130430121600,cucm1,location1,76,4 20130430122000,cucm,location,80,8 20130430122000,cucm1,location1,90,8 20130430140000,cucm1,location1,87,11 20130430140000, cucm,location,67,9

This is the required output

Code:

20130430121600, cucm, location,76,2 20130430121600,cucm1,location1,76,4 20130430122000,cucm,location,4,8 20130430122000,cucm1,location1,14,8 20130430140000,cucm1,location1,87,11 20130430140000, cucm,location,67,9

Requirements :
The first column represents YYYYMMDDHHMISS - the date along with the time . The first row, first column represents 2013 year Apr 30 12th hour and 16 min.
I should take delta of 4th column between consecutive rows when 2nd and 3rd column matches, and also the difference between the 1st column is not more than 1 hour

In my list file, first and third row matches in 2nd and 3rd column, and also the difference between the time column is not more than 1 hour, and so I take a diff of the fourth column : 80 -76 =4.

This gave me a solution without the timestamp column.
Can some one help me out.

Thanks in Advance

You need to convert your date to something integer, like seconds since 1970, before you can determine differences.
