NAME
uname -- display information about the system
SYNOPSIS
uname [-aiKmnoprsUv]
DESCRIPTION
The uname command writes the name of the operating system implementation to standard output. When options are specified, strings represent- ing one or more system characteristics are written to standard output. The options are as follows: -a Behave as though the options -m, -n, -r, -s, and -v were specified. -i Write the kernel ident to standard output. -K Write the FreeBSD version of the kernel. -m Write the type of the current hardware platform to standard output. -n Write the name of the system to standard output. -o This is a synonym for the -s option, for compatibility with other systems. -p Write the type of the machine processor architecture to standard output. -r Write the current release level of the operating system to standard output. -s Write the name of the operating system implementation to standard output. -U Write the FreeBSD version of the user environment. -v Write the version level of this release of the operating system to standard output. If the -a flag is specified, or multiple flags are specified, all output is written on a single line, separated by spaces. The -K and -U flags are intended to be used for fine grain differentiation of incremental FreeBSD development and user visible changes.
ENVIRONMENT
An environment variable composed of the string UNAME_ followed by any flag to the uname utility (except for -a) will allow the corresponding data to be set to the contents of the environment variable.
EXIT STATUS
The uname utility exits 0 on success, and >0 if an error occurs.
