Alerttail monitors a given file and executes a list of actions when a user-defined text pattern has been written to the file. For example, the user can pop up a GTK notification window when a certain message is written to a log file. Actions can be alerttail built in actions (GTK notify action, geoipLocalization action, or filtering text action) or a custom user defined shell command action. A Qt 4 GUI frontend helps with configuration.
