WHAT(1) 						    BSD General Commands Manual 						   WHAT(1)

NAME

     what -- show what versions of object modules were used to construct a file

SYNOPSIS

     what [-qs] [file ...]

DESCRIPTION

     The what utility searches each specified file for sequences of the form ``@(#)'' as inserted by the SCCS source code control system.  It
     prints the remainder of the string following this marker, up to a NUL character, newline, double quote, '>' character, or backslash.

     The following options are available:

     -q      Only output the match text, rather than formatting it.

     -s      Stop searching each file after the first match.

EXIT STATUS

     Exit status is 0 if any matches were found, otherwise 1.

SEE ALSO

     ident(1), strings(1)

STANDARDS

     The what utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').  The -q option is a non-standard FreeBSD extension which may not be avail-
     able on other operating systems.

HISTORY

     The what command appeared in 4.0BSD.

BUGS

     This is a rewrite of the SCCS command of the same name, and behavior may not be identical.

UNAME(1)						    BSD General Commands Manual 						  UNAME(1)

NAME

     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.

SEE ALSO

     feature_present(3), getosreldate(3), sysctl(3), uname(3), sysctl(8)

STANDARDS

     The uname command is expected to conform to the IEEE Std 1003.2 (``POSIX.2'') specification.

HISTORY

     The uname command appeared in PWB UNIX.

     The -K and -U extension flags appeared in FreeBSD 10.0.
