Full Discussion: Array problem in Bash Script
Top Forums UNIX for Beginners Questions & Answers Array problem in Bash Script Post 302983764 by Don Cragun on Sunday 16th of October 2016 10:41:10 PM

Your current code explicitly initializes the array using:
Code:
days=(9 8 7 6 5)

If you want to update the array and load those updated values the next time you run your script, you need to save the updated values in a file before you exit your script, and when you run your script you need to load the array from that file; not with the initialization step shown above.

Note that you also need to be sure that you never run more than one copy of your script at a time. If you have two copies of the script running concurrently, you have to be absolutely sure that they destroy the file saving your stored data by performing concurrent updates to that file.

make_combined_log2

make_combined_log.pl(1) 				      General Commands Manual					   make_combined_log.pl(1)

NAME

       make_combined_log.pl - make combined logfile from SQL database

SYNOPSIS

       make_combined_log.pl <days> <virtual host>

DESCRIPTION

       This perl script extracts the httpd access data from a MySQL database and formats it properly for parsing by 3rd-party log analysis tools.

       The  script  is	intended  to  be run out by cron. Its commandline arguments tell it how many days' worth of access records to extract, and
       which virtual_host you are interested in (because many people log several virthosts to one MySQL db.) This permits you  to  run	it  daily,
       weekly, every 9 days -- whatever you decide.

NOTE

       By  "days"  I  mean "chunks of 24 hours prior to the moment this script is run." So if you run it at 4:34 p.m. on the 12th, it will go back
       through 4:34 p.m. on the 11th.

KNOWN ISSUES

       Because GET and POST are not discriminated in the MySQL log, we'll just assume that all requests are  GETs.  This  should  have	negligible
       effect  on  any analysis software. This could be remedied IF you stored the full HTTP request in your database instead of just the URI, but
       that's going to cost you a LOT of space really quickly...

       Because this is somewhat of a quick hack it doesn't do the most robust error checking in the world. Run it by hand to  confirm  your  usage
       before putting it in crontab.
