isthere

File notifications made simple

Overview

isthere checks if a file exists otherwise it will send a notification email to the user in src/main/resources/main.config. If the file is not present the application will watch the expected directory until the file arrives. Once it does a second email will be sent out notifying you.

Setup

First you must declare an environment variables called ISTHERE_HOME that points to the isthere home directory. This is OS dependent for instance..

• On windows it might be %APP_DATA%\isthere\conf
• On Linux-esque machines it might be /etc/isthere/conf

All the configuration values are located in src/main/resources/main.config and the following properties must be set in order for the application to function...

• host The SMTP host to connect (string)
• user The SMTP account username (string)
• pass The SMTP account password (string)
• port Port number to connect (integer)
• emailTo The email address for notification emails to be sent
• emailFrom The emaill address to set in the FROM field

Usage

isthere was built to be run as a CRON job however any scheduling application will work with it. To execute the application enter the following in your terminal...

# Execute the appropriate wrapper script
$ ./isthere /path/to/file.txt

# Windows..
$ ./isthere.bat /path/to/file.txt

NOTE: If the file is present the application will immediately exit otherwise the application will run until the file arrives.
