  uname

  NAME

    uname - display information about the system

  SYNOPSIS

    uname [-aHmnpPrsUvxX]

  DESCRIPTION

    The uname(1) command writes the name of the operating system
    implementation to standard output. When options are specified, strings
    representing one or more system characteristics are written to standard
    output.

    The options are as follows:

    -a
        Behave as though the options -m, -n, -p, -r, -s, and -v were
        specified. For example, uname -a produces the output:
        Interix MyServer 3.5 SP-8.0.1967.1 x86 Pentium III/Celeron (rev0x0703)
        for a computer named MyServer, running the Interix subsystem release
        3.5, version SP-8.0.1967, on a Pentium III/Celeron platform.

    -H
        Write host operating system information. For example, uname -aH
        produces the output:
        Windows james 5.0 SP0 x86 Intel_x86_Family6_Model7_Stepping2
        for a computer named james, running Windows 2000 release 5.0, version
        SP0, on a Pentium III platform.

    -m
        Write a generic simple computer-type name. In this version, only x86
        is supported. For a description of the exact processor, use -p.

    -n
        Write the name of the system to standard output.

    -p
        Write the type of the current hardware platform to standard output.

    -r
        Write the current release level of the Interix subsystem to standard
        output. For example, on a computer running Interix subsystem release
        3.5, this is "3.5". When specified with the -H option, write the
        current release of the host operating system. For example, on a
        computer running Windows 2000 (release 5.0), this is "5.0".

    -s
        Write the name of the operating system implementation to standard
        output. On an Interix system, this is "Interix". When specified with
        the -H option, write the name of the host operating system. On an
        Interix system, this is "Windows".

    -U
        Print information based on the UNIX operating environment.

    -v
        Write the Interix version and build number. If the -H option is
        specified, write the service-pack level of the host operating system
        to standard output. This is the service pack number applied to the
        Windows operating system. If no service pack has been applied, it is
        SP0.

    -x
        Print command usage.

    -X
        Print expanded system information.

    If the -a flag is specified, or multiple flags are specified, all output
    is written on a single line, separated by spaces.

  DIAGNOSTICS

    The uname(1) utility exits 0 on success, and >0 if an error occurs.
