CRM114 is a Controllable Regex Mutilator and Smart Filter, designed for easy creation of filters for things like incoming email redirection, spam filtering, system logs, or monitoring processes. Filtering rules can be either hard-coded (such as regexes), soft-coded (calculated at runtime or read from an external file or process), or learned dynamically by phrase matching (as in Bayesian filtering, Markovian matching, Winnowing, or Hyperspatial classification). This makes it possible to create very accurate filters with very little actual work. Accuracies over 99.9% are achievable.
apachelogrotate.pl rotates and packs the logfiles of the Apache Web server on a Linux system without interrupting its service and without the need for a permanent change in the Web server configuration. Assuming that Apache is running, it will identify the log files which have to be rotated without any configuration, making it easy to install. By default, logfiles with more than 10 MB are rotated, but this parameter may be changed and/or a daily, monthly, or yearly rotation period can be configured. Documentation is included in the script itself.
