log4sh is an advanced logging framework for shell scripts (eg. sh, bash) that works similar to the logging products available from the Apache Software Foundataion (eg. log4j, log4perl).

log4sh provides different releases so that users can depend on functionality within a release series. It uses a variant of the X.Y.Z Semantic Versioning system.

  • X -- major release. Significant functionality has changed, and users of the code will definitely require changes to continue using it. These are extremely rare.
  • Y -- minor release. New functionality was added. To maintain stability for users, stable releases are numbered with even numbers (e.g. 1.4), with development releases numbered with odd numbers (e.g. 1.5). Development releases possibly include functionality that breaks backwards compatibility.
  • Z -- patch release. Bug fixes, and minor new functionality that remains 100% backwards compatible.

log4sh was originally hosted on Source Forge as https://sourceforge.net/p/log4sh/. It moved here in Sep 2017 to be hosted alongside the other projects by @kward (https://github.com/kward).
