SYNOPSIS
uname |
[-aimnprsvP] |
DESCRIPTION
Theuname 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,-r,-s, and-vwere specified. -i- Write the kernel ident to standard output.
-m- Write the type of the current hardware platform to standard output.
-n- Write the name of the system to standard output.
-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.
-v- Write the version level of this release of the operating system to standard output.
-P- Generates a default ABI: configuration string for dports / pkgng to the standard output, including odd-to-even version-munging.
-PP- Generates a default ABI: configuration string for dports / pkgng to the standard output, without version-munging.
If the -a flag is specified, or multiple
flags are specified, all output is written on a single line, separated by
spaces.
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.
A varsym composed of the string UNAME_
followed by any flag to the uname utility (except
for -a) will allow the corresponding data to be set
from the contents of the varsym. Environment variables override varsyms in
this case.
EXIT STATUS
The uname utility exits 0 on
success, and >0 if an error occurs.
