UNAME(1L)

NAME
uname - print system information

SYNOPSIS
uname [-snrvma] [--sysname] [--nodename] [--release] [--version] [--machine] [--all]

DESCRIPTION
This manual page documents the GNU version of uname. uname prints information about the machine and operating system it is run on. If no options are given, uname acts as if the -s option were given. If multiple options are given or the -a option is given, the selected information is printed in the order `snrvm' with a space between items.

  OPTIONS

-s, --sysname
    Print the operating system name.

-n, --nodename
    Print the machine's network node hostname.

-r, --release
    Print the operating system release.

-v, --version
    Print the operating system version.

-m, --machine
    Print the machine (hardware) type.

-a, --all
    Print all of the above information.

The long-named options can be introduced with `+' as well as `--', for compatibility with previous releases. Eventually support for `+' will be removed, because it is incompatible with the POSIX.2 standard.
