NAME
osinfo-query - Query information in the database SYNOPSIS
osinfo-query [OPTIONS...] TYPE [CONDITION-1 [CONDITION-2 ...]] DESCRIPTION
The "osinfo-query" command allows extraction of information from the database. TYPE can be one of "os", "platform", "device", or "deployment". With no conditions specified, all entities of the given type will be listed. # List all operating systems $ osinfo-query os Short ID | Name ... ----------------------+----------- centos-6.0 | CentOS 6.0 ... centos-6.1 | CentOS 6.1 ... ... Conditions allow filtering based on specific properties of an entity. For example, to filter only distros from the Fedora Project, use # List all operating systems $ osinfo-query os vendor="Fedora Project" Short ID | Name ... ----------------------+-------------- fedora1 | Fedora Core 1 ... fedora2 | Fedora Core 2 ... ... The set of fields which are printed can be controlled using the "--fields" command line argument: # List all operating systems $ osinfo-query --fields=short-id,version os vendor="Fedora Project" Short ID | Version ----------------------+---------- fedora1 | 1 fedora2 | 2 ...

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]) Product: %[sp] (%[ap]) Technology: %[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. EXAMPLE
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" OpenPKG binary RPM packages $ platform -c -L -S "" -C "+" -F "%ap-%sp" README files $ platform -v -F "%sp (%ap)" $ platform -v -F "%sc (%ac)" 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. SEE ALSO
