Homework & Coursework Questions

We are not here to do your homework for you. Leaving section 3 in the homework template blank isn't a good starting point.

If you put in some effort and show us what you have tried, we can help you hone your solution to one that will get the job done. If you aren't willing to show us that you are making an effort, there isn't much more that we will be willing to do for you.

All that you have shown us is that you can use cut with space as a delimiter to select part of an input line. Could you use cut with a different delimiter to get rid of the [?

What tools are you allowed to use for this assignment? You have shown us cut and we assume that you can use some shell (but we don't know which shell). You have suggestions to use GNU date and awk. Are these available for this assignment? Can you use a 1993 or later version of ksh (which can also perform simple calculations to get the date 10 days ago)?

Are you looking for a date 14 days ago to the second? Or, are you looking for a date starting at midnight almost 14 days ago? Whether or not you can use the date utility depends on what operating system and shell you're using?

Thank you for your helps.

I have thought about how to approach how to write this program but did not knowing how the log system work. There fore, I ask some questions here may offend the integrity of the forum.

First I thought if I knew how to manipulate the date string then I can control the log count of every 14 days. So I wonder how to grep things and strip things off. I had problem with bracket attach to date format such as

Code:

[15/Nov/…….

From the last lecture we have learned using Tr command I found it is useful to apply on how to remove the bracket.

I realized the easiest way to get the total requests of every 14 days
is find the line number of every break point of 14 days…… 0, 14, 24, 42 etc.

Pseudo:
Find the last line of the most current time in log file
Find the line number of request 14 days ago ("+%d/%b/%Y:%H:%M")
Then subtract the different to get the total number request of 14 days ago.


Thank you again,
