Hi,

I have file as above. I need to check if there is a way to check if the ones in bold are in sequence. the file may contain upto 5000 records and I need to check for sequence for only ones in bold. Please help. (If I can have an answer in awk it will be great since arrays in perl will have performance related issues)

Thanks,
Arun

What have you tried so far?

Currently I have 2 functions, one to check if the elements are in sequence and the other to get only those part of the file that needs to be checked for sequence

1) Cut only the columns of file that needs sequence checking (I have attached file. I wrote the function in Editplus for indentation)
2) to check if the elements are in sequence as below :

Code:

sub is_increasing_array {
    return unless @_;
    return 1 if @_ == 1;

    foreach (1 .. $#_) {
        if ($_[$_] != $_[$_ - 1] + 1)    {
            return ($_[$_] , $_[$_ - 1]);
        }

    return 1;
}

I have to mention that there are two hash maps which are used. one contains the start value from where the sequence validation needs to be performed and other has the name of the files on which validation has to be performed.

In the files the position of the columns on which it has to be performed may change. I have handled that part. I actually needed to know if we can use awk to check for sequence Or a Regex for the same (I did not ask this before)

Please advise

Thanks

Sorry, I gave a wrong solution. My mistake. Apologies.

OK,
I'll need more information.
Could you please post a bigger sample of your input? I need to know if you're interested in all the records (untill the end of the file) after the line containing adad: ada/ada/ada/adad/ada.

And the numbers to be verified are:

Code:

621300020985821
621300020985822
...

and

Code:

89234010001179436212
89234010001179436220
...

?

I.e. the first one is OK, the second not?
What should happen if the numbers are not in sequence?
