OPTIONS
       -v, --version

       -c, --codename

	      Display the codename according to the distribution release.

       -a, --all

	      Display all of the above information.

       -s, --short

	      Display all of the above information in short output format.

       -h, --help

	      Display this message.

FILES
       If  the	installation  is LSB compliant, the "/etc/lsb-release" file should contain the LSB_VERSION field. The value of the field should be
       the version number of the LSB specification against which the installation is compliant. If the installation is not  compliant,	the  above
       field should not be present.

       Optional  fields  are  DISTRIB_ID, DISTRIB_RELEASE, DISTRIB_CODENAME, DISTRIB_DESCRIPTION and can be used to overwrite information which is
       parsed from the next file.

       The "/etc/[distrib]-release" file contains a description line which is parsed to get information (especially on currently non-LSB compliant
       systems).

       The required line style is:
       "Distributor release x.x (Codename)"

       Where Distributor can be a couple of words, but then concatenated (i.e. Linux Foo BarLinux Linux -> FooBarLinux),
       x.x starts with a digit followed by any non-blank characters, Codename will also be concatenated (blanks cleanup only).

       And release is a keyword not to be used in DISTRIB_DESCRIPTION if you don't want to overwrite "/etc/[distrib]-release" data.

       Notice:	To  support  the Debian distributions' lack of information (see "/etc/debian_version" file) some have been directly added into the
       lsb_release script.

EXAMPLES
       The /etc/lsb-release file contains:

       LSB_VERSION="1.0"
       DISTRIB_DESCRIPTION="I enjoy using my distrib"

       And the /etc/foobar-release file contains:

       My Linux Distrib release 1.0RC4 (TryIt)

       $ ./lsb_release --all
       LSB Version:    1.0
       Distributor ID: MyDistrib
       Description:    I enjoy using my distrib
       Release:        1.0RC4
       Codename:       TryIt

       $ ./lsb_release -a -s
       1.0 MyDistrib "I enjoy using my distrib" 1.0RC4 TryIt

       Then simply without the "/etc/lsb-release" file, that means result on a non-LSB compliant distrib:
       $ ./lsb_release -a
       LSB Version:    n/a
       Distributor ID: MyDistrib
       Description:    My Linux Distrib release 1.0RC4 (TryIt)
       Release:        1.0RC4
       Codename:       TryIt
