NAME

       shtool-platform - GNU shtool Unix platform identification

SYNOPSIS

       shtool platform [-F|--format format] [-S|--sep string] [-C|--conc string] [-L|--lower] [-U|--upper]
       [-v|--verbose] [-c|--concise] [-n|--newline] [-d|--debug] [-t|--type type] [-n|--newline] [-d|--debug]

DESCRIPTION

       shtool platform is a flexible Unix platform identification program.  It distinguishes a platform
       according to its hardware architecture and operating system. For both there is a class, product and
       technology identification. For each of those six identifications, there is a verbose, regular and concise
       version.

       This leads to eighteen (2x3x3) available identification strings for each platform, from which usually 2
       are chosen in a particular situation.  This is done by assembling the platform identification string
       using a format string containing one or more identification constructs of the forms ""%[xx]"" (verbose),
       ""%{xx}"" (regular) and ""%<xx>"" (concise).

OPTIONS

       The following command line options are available.

       -F, --format format
           This option controls the output formatting of this program. It is a plain-text string with the
           ""%"xx" constructs which expand to the various platform information strings. ""%{"xx"}"" is the
           canonical regular version of the information. ""%["xx"]"" is the verbose version of the information.
           ""%<"xx">"" is the concise version of the information. In total, the following constructs are
           available for expansion:

            %[ac]    verbose hardware architecture class
            %{ac}    regular hardware architecture class
            %<ac>    concise hardware architecture class

            %[ap]    verbose hardware architecture product
            %{ap}    regular hardware architecture product
            %<ap>    concise hardware architecture product

            %[at]    verbose hardware architecture technology
            %{at}    regular hardware architecture technology
            %<at>    concise hardware architecture technology

            %[sc]    verbose operating system class
            %{sc}    regular operating system class
            %<sc>    concise operating system class

            %[sp]    verbose operating system product
            %{sp}    regular operating system product
            %<sp>    concise operating system product

            %[st]    verbose operating system technology
            %{st}    regular operating system technology
            %<st>    concise operating system technology

           The default format string is ""%{sp} (%{ap})"", providing the regular operating system and hardware
           architecture product information.

       -S, --sep string
           This option sets the word separation string for the platform information strings. By default it is ""
           "" (whitespace). It is especially used for separating the operating system name and the operating
           system version.

       -C, --conc string
           This option sets the word concatenation string for the platform information strings. By default it is
           ""/"". It is especially used to concatenate multiple parts in operating system name and version
           parts.

       -L, --lower
           This options enforces conversion of the output to all lower case.

       -U, --upper
           This options enforces conversion of the output to all upper case.

       -v, --verbose
           This option enforces verbose versions of all expansion constructs in format string of option -F. It
           is equal to specifying all expansion constructs as ""%["xx"]"".

       -c, --concise
           This option enforces concise versions of all expansion constructs in format string of option -F. It
           is equal to specifying all expansion constructs as ""%<"xx">"".

       -n, --no-newline
           This option omits the usual trailing newline character in the output.

       -t, --type type
           This option is a meta option which internally sets options -F, -S, -C, -L, -U, -v or -c according to
           TYPE. It can be used to easily specify various commonly known outputs. The following TYPEs are
           available:

           binary
               Binary Package Id (OpenPKG RPM).  This is equal to ""-F '%<ap"-%<sp>' -L -S '' -C '+'>" and
               results in outputs like ""ix86-freebsd4.9"" and ""ix86-debian3.0"".

           build
               Build-Time Checking (OpenPKG RPM).  This is equal to ""-F '%<at"-%<st>' -L -S '' -C '+'>" and
               results in outputs like ""i686-freebsd4.9"" and ""i586-linux2.4"".

           gnu GNU config.guess Style Id.  This is similar to build and is equal to ""-F '"%<at"-unknown-%<st>'
               -L -S '' -C '+'>" and results in outputs like ""i686-unknown-freebsd4.9"" and
               ""i586-unknown-linux2.4"".

           web HTTP Server Header Id.  This is equal to ""-F '"%<sp"-%<ac>' -S '/' -C '+'>" and results in
               outputs like ""FreeBSD/4.9-iX86"" and ""Debian/3.0-iX86"".

           summary
               Human Readable Verbose Summary Information. This is equal to ""-F 'Class: %[sc] (%[ac])\nProduct:
               %[sp] (%[ap])\nTechnology: %[st] (%[at])' -S ' ' -C '/'"" and results in outputs like:

                Class:      4.4BSD (iX86)
                Product:    FreeBSD 4.9-RC (iX86)
                Technology: FreeBSD 4.9-RC (i686)

               and

                Class:      LSB (iX86)
                Product:    Debian GNU/Linux 3.0 (iX86)
                Technology: GNU/Linux 2.2/2.4 (i686)

           all-in-one
               All-In-One Full-Table Information. This just outputs really all 2x2x3 identification strings as a
               table.

       -d, --debug
           This option enables some internal debugging messages.

       -V, --version
           This option outputs the version information of shtool platform only.

       -h, --help
           This option outputs the usage information of shtool platform only.

       The following real-life use cases are known:

       OpenPKG build-time decisions
            $ platform -c -L -S "" -C "+" -F "%at-%st"
            $ platform -c -L -S "" -C "+" -F "%ac-%sc"

       Debugging
            $ platform --type=all-in-one

SUPPORT

       shtool platform currently knows the following particular Unix platforms in detail: FreeBSD, NetBSD,
       OpenBSD, Linux, Sun Solaris, SCO UnixWare, QNX Neutrino, SGI IRIX, HP HP-UX, HP Tru64, IBM AIX and Apple
       Mac OS X Darwin.

       All other Unix platforms are recognized through generic uname(1) information and so usually can be
       identified sufficiently, although the identification might be not as precise as possible.

HISTORY

       shtool platform was implemented in September 2003 by Ralf S.  Engelschall for use in the OSSP and OpenPKG
       projects. It was prompted by the need in OpenPKG to have both product (for RPM filenames) and technology
       (for build-time decisions) identifiers for the Unix platforms, OpenPKG packages are maintained for. It
       was inspired by the GNU config.guess and the old GNU shtool guessos command.

       The major difference to GNU config.guess is that shtool platform does not use a vendor identification
       (cannot be determined most of the time and is not used at all in all projects I've ever seen) and is a
       lot more flexible (class, product and technology identifications combined with verbose, regular and
       concise outputs). The drawback of shtool platform is that it (still) knows less particular platforms,
       although the generic platform identification is sufficient enough most of the time.
