UNAME(1)                FreeBSD General Commands Manual               UNAME(1)

NAME
     uname - display information about the system

SYNOPSIS
     uname [-amnprsv]

DESCRIPTION
     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
             specified.

     -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.

     If the -a flag is specified, or multiple flags are specified, all output
     is written on a single line, separated by spaces.

DIAGNOSTICS
     The uname utility exits 0 on success, and >0 if an error occurs.
