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
