Overview

log4sh runs along the same lines as the other excellent logging services from the Apache Software Foundation. It adds to that list the ability to integrate powerful logging capabilities into a shell script.

log4sh was originally developed to solve a logging problem I had in some of the production environments I have worked in where I either had too much logging, or not enough. Cron jobs in particular caused me the most headaches with their constant and annoying emails telling me that everything worked, or that nothing worked but not a detailed reason why. I now use log4sh in environments where logging from shell scripts is critical, but where I need more than just a simple "Hello, fix me!" type of logging message. If you like what you see, or have any suggestions on improvements, please feel free to drop me an email. If there is enough interest in the project, I will develop it further.

log4sh has been developed under the Bourne Again Shell (/bin/bash) on Linux, but great care has been taken to make sure it works under the default Bourne Shell of Solaris (/bin/sh) as this happens to be the primary production platform used by myself.

Tested Operating Systems

Tested Shells

  • Bourne Shell (sh)
  • BASH - GNU Bourne Again SHell (bash)
  • DASH (dash)
  • Korn Shell (ksh)
  • pdksh - the Public Domain Korn Shell (pdksh)

Downloading

There are two current release series of log4sh available. The 1.4 series is the stable release, and it contains only bugfixes. It is considered stable enough for production use. The 1.5 series is meant for new features and is still under development. Generally, the 1.5 series should be stable enough to use in a production environment as it is run through unit testing before being released, but there are no guarantees that everything works so it would be best to test it out first.

The latest version of log4sh can be downloaded from the SourceForge Project Filelist. The test results can be found in the testresults directory. The earliest available are for the 1.3.7 release.
