uname -- display information about the system
The uname 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 -v were speci-
-i Write the kernel ident to standard output.
-m Write the type of the current hardware platform to standard out-
-n Write the name of the system to standard output.
-p Write the type of the machine processor architecture to standard
-r Write the current release level of the operating system to stan-
-s Write the name of the operating system implementation to standard
-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.
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.
The uname utility exits 0 on success, and >0 if an error occurs.
