UNAME(1) General Commands Manual UNAME(1)NAME
uname - display information about the system
SYNOPSIS
uname [-amnrsv]
DESCRIPTION
The uname command writes the name of the operating system implementation to standard output. When options are specified, strings repre-
senting 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.
-m Write the type of the current hardware platform to standard output.
-n Write the name of the system 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.
-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 uname utility exits 0 on success, and >0 if an error occurs.

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.
