Shell Programming and Scripting

1.Write an automated shell program(s) that can create, monitor the log files and report the issues for matching pattern.

(i) Conditions for creating log files.
Log file is created with date (example 2010_03_27.log). If the log file size is 10 Mb for a particular day then automatically the log file will be rotated with sequence number (example, on a particular day if the log file crossed 10 MB while the data insert ii n progress, the program should rotate the log file with a sequence number YYYY_MM_DD_sequence_number.log)

(ii) Condition for reading the data for pattern matching
The report with matched pattern should be reported at the earliest for effective business decision. The data that is already processed shouldn't be considered for analysis for pattern matching.

Code:

 Example file with sample data and mattching patterns
file01.log
2010-03-18 24:50:50:500: WorkingThread-1:User_Authorization_Failed session-id-10002033
2010-03-18 24:50:50:550: WorkingThread-1:User_Authentication_Failed session-id-10002033
2010-03-18 24:52:50:500: WorkingThread-1:User_Access_Locked session-id-10002033

Analyze the log for following pattern's:
1. Report number of 'User_Authorization_Failed'
2. Report number of 'User_Authentication_Failed'
3. Report number of 'User_Access_Locked'

Everyone at the UNIX and Linux Forums gives their best effort to reply to all questions in a timely manner. For this reason, posting questions with subjects like "Urgent!" or "Emergency" and demanding a fast reply are not permitted in the regular forums.

For members who want a higher visibility to their questions, we suggest you post in the Emergency UNIX and Linux Support Forum. This forum is given a higher priority than our regular forums.

Posting a new question in the Emergency UNIX and Linux Support Forum requires forum Bits. We monitor this forum to help people with emergencies, but we do not not guarantee response time or best answers. However, we will treat your post with a higher priority and give our best efforts to help you.

If you have posted a question in the regular forum with a subject "Urgent" "Emergency" or similar idea, we will, more-than-likely, close your thread and post this reply, redirecting you to the proper forum.

Of course, you can always post a descriptive subject text, remove words like "Urgent" etc. (from your subject and post) and post in the regular forums at any time.


Thank you.

Hello,

Per our forum rules, all threads must have a descriptive subject text. For example, do not post questions with subjects like "Help Me!", "Urgent!!" or "Doubt". Post subjects like "Execution Problems with Cron" or "Help with Backup Shell Script".

The reason for this is that nearly 95% of all visitors to this site come here because they are referred by a search engine. In order for future searches on your post (with answers) to work well, the subject field must be something useful and related to the problem!

In addition, current forum users who are kind enough to answer questions should be able to understand the essence of your query at first glance.

So, as a benefit and courtesy to current and future knowledge seekers, please be careful with your subject text. You might receive a forum infraction if you don't pay attention to this.

Thank you.
