OS4X plugin os4xplugin bzip2

Purpose

Compressing each individual file defined in the passed XML using bzip2. The original files are exchanged in the file system using the bzip2 process. The extension ".bz2" is appended to each file. The new file name is changed in the XML file. The compression node "compression" in the XML is changed to "bzip2" for each file.

Requirements

• File /etc/os4x.conf or configuration file referenced by environment variable $OS4X_CFGFILE. The temporary directory and the license file are obtained via the database that is configured here.

Configuration

The program "bzip2" is searched for in the PATH of the shell under which the plugin is started. This means that the bzip2 version used can be influenced by clever positioning or definition of the default PATH.

The compression factor (0-9, where 0 represents no compression and 9 is the highest compression level) can be passed when calling the plugin via the optional configuration XML. The default compression factor is 9.

Return codes

• 0: everything OK
• 1: Number of parameters != 1; Config file /etc/os4x.conf not found; Config in database not readable; License not valid; XML file invalid
• all others: return value of the bzip2 call
