Shell Programming and Scripting

Hello friends,
I am newbie in programing. I am facing some problems in awk. Please help me.
I have a file with many data sets. Each data set is separated by an empty line. For example
Col1 Col2 Col3 Col4 Col5
0.85 0.07 Fre 42:86 25
0.73 0.03 frp 21:10 28
0.64 0.04 Fre 42:86 63
0.47 0.08 nie 25:76 32
0.37 0.01 veb 00:71 26
0.63 0.48 Fre 42:86 65
0.65 0.32 frp 21:10 19
0.47 0.08 nie 25:76 43

0.53 0.56 nie 25:76 52
0.32 0.43 veb 00:71 18
0.85 0.07 Fre 43:86 40
0.65 0.32 frp 21:10 30
0.85 0.07 Fre 43:86 50
0.53 0.56 nie 25:76 20
0.65 0.32 frp 21:10 40
0.85 0.07 Fre 43:86 50

0.85 0.07 Fre 43:86 60
0.32 0.43 veb 01:71 30
0.32 0.43 veb 01:71 80
0.65 0.32 frp 21:10 40
0.85 0.07 Fre 43:86 70
0.53 0.56 nie 25:76 60
0.65 0.32 frp 21:10 50

In this data Col4 is primary key.I want to check that if Col5 value is increasing for a specific record in first data set.If it is true for some records(as for "Fre 42:86 25/Fre 42:86 63/Fre 42:86 65" and "nie 25:76 32/nie 25:76 43") then read the next data set and check if the Col5 value for these records(Fre 42:86 and nie 25:76) is greater than 30. If true then just count it.So all the values in Col5 for "Fre 42:86" is greater than 30 but not for "nie 25:76" as there is one record "nie 25:76 20" and it's Col5 value is less than 30.Therefore I have 1 count for first data set.
Similarly then I should check the second data set that if Col5 value is increasing for a specific record in second data set.If true then read the next(third) data set and check if Col5 value for those records is greater than 30.If true then just count it and so on.
Please if anyone can guide/suggest/help me in solving this problem.
Thanks in advance.

I am not quite understanding what the output is suppose to be. Can you give an example of input with desired output as well?

Hello Bubbajoe,
The input should be a file with many data sets separated by blank line as shown in my previous post.Check the first data set if Col5 value for a specific record is increasing e.g Fre 42:86 and nie 25:76. For both these records in first data set the Col5 value is increasing. As we can see in the following first data set.
0.85 0.07 Fre 42:86 25
0.73 0.03 frp 21:10 28
0.64 0.04 Fre 42:86 63
0.47 0.08 nie 25:76 32
0.37 0.01 veb 00:71 26
0.63 0.48 Fre 42:86 65
0.65 0.32 frp 21:10 19
0.47 0.08 nie 25:76 43

Now read 2nd data set and check if for these records(Fre 42:86 and nie 25:76) the Col5 value is greater than 30. So if we look at the following 2nd data set, all the Col5 values for record(Fre 42:86) which was selected from first data set is greater than 30 and for record (nie 25:76) there is a Col5 value in 2nd data set which is less than 30 (0.53 0.56 nie 25:76 20). So we found one record which fulfilled the conditions(count=1).
0.53 0.56 nie 25:76 52
0.32 0.43 veb 00:71 18
0.85 0.07 Fre 43:86 40
0.65 0.32 frp 21:10 30
0.85 0.07 Fre 43:86 50
0.53 0.56 nie 25:76 20
0.65 0.32 frp 21:10 40
0.85 0.07 Fre 43:86 50

Similarly,now we will check the 2nd data set if Col5 value for a specific record is increasing.If we found any record in 2nd data set then we will read the 3rd data set and check if the Col5 value for those record in greater than 30. If true then again just count it.
and so on for next data sets.
I hope this time you got my problem but let me know if you still have any confusion.
Thank you so much for your time and cooperation.
