that 4th column is hourly dates. i have gap in 1000 to 13000 and i want to fill this gaps with 5th columns interpolation.
can i do this with awk? to have:
I should do it in two steps:
1- filling the gaps maybe by reading the file in a date loop and add the gap lines
2- get the values for new lines by interpolation.
Please wrap code and data input/output in CODE tags.
It make it far easier to read and preserves multiple spaces for indenting or fixed width data.
Hi emirzaei,
RudiC did include this note with his suggestion:
Quote:
Note: it doesn't allow for crossing midnight.
Why don't you try to extend the awk script RudiC supplied to so it can handle missing lines that cross date boundaries
If you get it to work, post your script (in CODE tags) so others reading this thread can learn from what you have done.
If you can't get it to work, show us what you have tried (in CODE tags) and show us what it is doing (in CODE tags) and explain what still needs to be done. We are here to help you learn how to write your own code; not to act as your unpaid programming staff updating suggestions to meet changing requirements after suggestions are posted.
Can we assume that there will never be a string of missing entries that extends for more than 23 hours? (If we can make that assumption, we don't have to perform any arithmetic on dates; we just have to note that the date changed between two entries and the hours on adjacent entries aren't sequential.)
What operating system and shell are you using? (Tools available for performing arithmetic on dates varies considerably from system to system and shell to shell.) Telling us what operating system and shell you're using in the 1st post in a thread is always a good idea. Doing so will lead to fewer suggestions being made that will not work in your environment.
Hi,
I have a data sample as shown below. I want to fill in the left column so that the line will be continuous. For example, between 1 and 5 should be 2,3,4. And corresponding values in the right column will be 0. Thus the expected data should look like that:
1 1
1 10
1 2
1 3
1 5
1 6
2 0... (6 Replies)
Hello,
I have two files of same structure except some rows are missing randomly in each file. How do I fill the missing rows to have the exact ID column (S01 ~ S96) and rest columns filled with "0" with awk? The purpose of this step is to join the two files side by side. The closest thread is... (17 Replies)
