Ubuntu Script using PostFix, Unzip, Convert .xls file to .csv

********************************************************** PLEASE DO NOT BID UNLESS YOU KNOW WHAT YOU'RE DOING AND CAN DELIVER BY DUE DATE - NOT NEGOTIABLE Please read the detailed requirements as well and see the attached .xls file. ============================================== I need a script written that runs every night. Here is the situation... We receive an email week-days (Monday-Friday) at about 9pm (server time) at a particular email address, e.g. myemail@domain.com. Email: From-address is 'orders@[login to view URL]' Subject has a prefix as Company1 and a suffix as YYYYMMDD. Email contains a .zip file The zip filename is displayed as YYYYMMDD Company2 Daily Reports .zip file. If email and/or .zip file not received by 5am next day, then send a warning email to email1@[login to view URL], email2@[login to view URL], email3@domain.com. The .zip contains a few files. We are only interested in the filename defined as [login to view URL] Take this file and convert it to .CSV [login to view URL] *** In my tests simply changing the extension from .xls to .csv works. Please test this first before implementing any other code. .xls file attached. Place [login to view URL] in a predefined folder. Send email to email1@[login to view URL] if process was successful. Ensure duplicates are avoided. Only 1 file per date permitted. If duplicate file arrives, send warming email to email1@domain.com. No imports required for Saturdays and Sundays. So after processing Friday's email (about 9pm Friday), nothing is required until Monday 9pm. Specify a start date so old emails are not processed (emails received before this script is implemented). Please note: You are more than welcome to the use of 3rd party scripts(s) that does this, especially the .XLS -> .CSV conversion - but please test it whatever with the rest of the script. No point reinvesting the wheel. Your primary focus should be 100% automation. ## Deliverables System Specs: * Mail Server: Postfix, configured to use dovecot for delivery. (Using virtual hosts and virtual users: not sure if this can be important) * Format: Maildir * OS: Ubuntu 10.04.4 If you need help with .xls to .csv conversion, then please consider these resources but you should test with simply changing the extension first.
