This allows module support to be handled easily by # package install/removal without a need to edit lsb-release on the fly. # - Correct license: FSG == Free Standards Group, Inc. # # * Changes in 1.4 # - "awk" not needed anymore (Loic Lefort) # - fixed bug #121879 reported by Chris D. Faulhaber, # some shells doesn't support local variables # - fixed a bug when single parameter sets many args including -s # - function DisplayProgramVersion (undocumented) now exits script like Usage # - cosmetic changes in comments/outputs # # * Changes in 1.3 # - No changes in script, only in build infrastructure # # * Changes in 1.2 # - Fixed more bash'isms # - LSB_VERSION is no longer required in /etc/lsb-release file # # * Changes in 1.1 # - removed some bash-ism and typos # Notice: script remains broken with ash because of awk issues # - changed licence to FSG - "Free Software Group, Inc" # - fixed problem with --short single arg call # - changed Debian specifics, codename anticipates release num # # Description: # Collect information from sourceable /etc/lsb-release file (present on # LSB-compliant systems) : LSB_VERSION, DISTRIB_ID, DISTRIB_RELEASE, # DISTRIB_CODENAME, DISTRIB_DESCRIPTION (all optional) # Then (if needed) find and add names from /etc/lsb-release.d # Then (if needed) find and parse the /etc/[distro]-release file ############################################################################### # DECLARATIONS ############################################################################### # This script version SCRIPTVERSION="2.0" # Defines the data files INFO_ROOT="/etc" # directory of config files INFO_LSB_FILE="lsb-release" # where to get LSB version INFO_LSB_DIR="lsb-release.d" # where to get LSB addon modules INFO_DISTRIB_SUFFIX="release" # <distrib>-<suffix> ALTERNATE_DISTRIB_FILE="/etc/debian_version" # for Debian [based distrib] ALTERNATE_DISTRIB_NAME="Debian" # " CHECKFIRST="/etc/centos-release" # check it before file search # Defines our exit codes EXIT_STATUS="0" # default = Ok :) ERROR_UNKNOWN="10" # unknown error ERROR_USER="1" # program misuse ERROR_PROGRAM="2" # internal error ERROR_NOANSWER="3" # all required info not available # typically non LSB compliant distro! # Defines our messages MSG_LSBVER="LSB Version:\t" MSG_DISTID="Distributor ID:\t" MSG_DISTDESC="Description:\t" MSG_DISTREL="Release:\t" MSG_DISTCODE="Codename:\t" MSG_NA="n/a" MSG_NONE="(none)" MSG_RESULT="" # contains the result in case short output selected # Description string delimiter DESCSTR_DELI="release" ############################################################################### # FUNCTIONS ############################################################################### # Display Program Version for internal use (needed by help2man) DisplayProgramVersion() { echo "FSG `basename $0` v$SCRIPTVERSION" echo echo "Copyright (C) 2000, 2002, 2004 Free Standards Group, Inc." echo "This is free software; see the source for copying conditions.
