logalert is a log file monitor tool which executes a specific action whenever it matches a string (pattern) occurrence. It reads an entire file (or starts at the end, just like tail -f) and keeps track of any changes, waiting for a specific pattern (a syslog process error, a user login, etc.) and starting an action you define when it finds it. It uses regular expressions to match the pattern occurrence and executes commands via shell interaction. It deals with the log rotation and temporary removals normally used by sysadmins.
