UNIX for Dummies Questions & Answers

hi all!

I am VB developer and i am trying to automate a process in UNIX for which i request your help.

I want to learn the technique by which we can write batch process in unix server to search for a list of files and to note down files that are missing from the list in the form of a log so that this log is mailed for notification of the specific file that is missing.

I do not know much about unxi except for very few basic commands.I request any help in this regard.

Thanks to this superb website !!

You could..

1. enumerate through each file and see if it exists, if not append name to a file, after the enumeration if that file is not empty, then email it

or

2. have the list of files in sorted order, do a list of the directory, run that listing through "sort" then "diff" with the original list. If there is a difference, email the difference.

first:
touch /directory/list1
touch /directory/list2
ls > directory/list1

then continually run this:

ls /directory/ > directory/list2
diff /directory/list1 /directory/list2 >> /logs/directorylog.log

If there is a difference between the lists then this will show up in the directorylog.log file.

Good luck scripting the mail commands and triggers. It should be fairly simple.
