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.
