NAME

       pegasus-version - print or match the version of the toolkit.

SYNOPSIS

       pegasus-version [-Dproperty=value] [-m [-q]] [-V] [-f] [-l]

DESCRIPTION

       This program prints the version string of the currently active Pegasus toolkit on stdout.

       pegasus-version is a simple command-line tool that reports the version number of the Pegasus distribution
       being used. In its most basic invocation, it will show the current version of the Pegasus software you
       have installed:

           $ pegasus-version
           3.1.0cvs

       If you want to know more details about the installed version, i.e. which system it was compiled for and
       when, use the long or full mode:

           $ pegasus-version -f
           3.1.0cvs-x86_64_cent_5.6-20110706191019Z

OPTIONS

       -Dproperty=value
           The -D option allows an experienced user to override certain properties which influence the program
           execution, among them the default location of the user’s properties file and the PEGASUS_HOME
           location. One may set several CLI properties by giving this option multiple times.

           The -D option(s) must be the first option on the command line. CLI properties take precedence over
           the file-based properties of the same key.

       -f, --full
           The --full mode displays internal build metrics, like OS type and libc version, addition to the
           version number. It appends the build time as time stamp to the version. The time stamp uses ISO 8601
           format, and is a UTC stamp.

       -l, --long
           This option is an alias for --full.

       -V, --version
           Displays the version of the Pegasus planner you are using.

       --verbose
           is ignored in this tool. However, to provide a uniform interface for all tools, the option is
           recognized and will not trigger an error.

RETURN VALUE

       The program will usually return with success (0). In match mode, if the internal version does not match
       the external installation, an exit code of 1 is returned. If run-time errors are detected, an exit code
       of 2 is returned, 3 for fatal errors.

ENVIRONMENT VARIABLES

       JAVA_HOME
           should be set and point to a valid location to start the intended Java virtual machine as
           $JAVA_HOME/bin/java.

EXAMPLE

           $ pegasus-version
           3.1.0cvs

           $ pegasus-version -f
           3.1.0cvs-x86_64_cent_5.6-20110706191019Z
