NAME

     c89 -- POSIX.2 C language compiler

SYNOPSIS

     c89 [-cEgOs] [-D name[=value]] ... [-I directory] ... [-L directory] ... [-o outfile] [-U name] ... operand ...

DESCRIPTION

     This is the name of the C language compiler as required by the IEEE Std 1003.2 (``POSIX.2'') standard.

     The c89 compiler accepts the following options:

     -c      Suppress the link-edit phase of the compilation, and do not remove any object files that are produced.

     -D name[=value]
	     Define name as if by a C-language #define directive.  If no ``=value'' is given, a value of 1 will be used.  Note that in order to
	     request a translation as specified by IEEE Std 1003.2 (``POSIX.2'') you need to define _POSIX_SOURCE either in the source or using
	     this option.  The -D option has lower precedence than the -U option.  That is, if name is used in both a -U and a -D option, name
	     will be undefined regardless of the order of the options.	The -D option may be specified more than once.

     -E      Copy C-language source files to the standard output, expanding all preprocessor directives; no compilation will be performed.

     -g      Produce symbolic information in the object or executable files.

     -I directory
	     Change the algorithm for searching for headers whose names are not absolute pathnames to look in the directory named by the directory
	     pathname before looking in the usual places.  Thus, headers whose names are enclosed in double-quotes ("") will be searched for first
	     in the directory of the file with the #include line, then in directories named in -I options, and last in the usual places.  For
	     headers whose names are enclosed in angle brackets (<>), the header will be searched for only in directories named in -I options and
	     then in the usual places.	Directories named in -I options shall be searched in the order specified.  The -I option may be specified
	     more than once.

     -L directory
	     Change the algorithm of searching for the libraries named in the -l objects to look in the directory named by the directory pathname
	     before looking in the usual places.  Directories named in -L options will be searched in the order specified.  The -L option may be
	     specified more than once.

     -o outfile
	     Use the pathname outfile, instead of the default a.out, for the executable file produced.

     -O      Optimize the compilation.

     -s      Produce object and/or executable files from which symbolic and other information not required for proper execution has been removed
	     (stripped).

     -U name
	     Remove any initial definition of name.  The -U option may be specified more than once.

     An operand is either in the form of a pathname or the form -l library.  At least one operand of the pathname form needs to be specified.
     Supported operands are of the form:

	   file.c      A C-language source file to be compiled and optionally linked.  The operand must be of this form if the -c option is used.

	   file.a      A library of object files, as produced by ar(1), passed directly to the link editor.

	   file.o      An object file produced by c89 -c, and passed directly to the link editor.

	   -l library  Search the library named liblibrary.a.  A library will be searched when its name is encountered, so the placement of a -l
		       operand is significant.

STANDARDS

     The c89 utility is believed to comply with IEEE Std 1003.2 (``POSIX.2'').

NAME

     mv -- move files

SYNOPSIS

     mv [-f | -i | -n] [-v] source target
     mv [-f | -i | -n] [-v] source ... directory

DESCRIPTION

     In its first form, the mv utility renames the file named by the source operand to the destination path named by the target operand.  This
     form is assumed when the last operand does not name an already existing directory.

     In its second form, mv moves each file named by a source operand to a destination file in the existing directory named by the directory oper-
     and.  The destination path for each operand is the pathname produced by the concatenation of the last operand, a slash, and the final path-
     name component of the named file.

     The following options are available:

     -f      Do not prompt for confirmation before overwriting the destination path.  (The -f option overrides any previous -i or -n options.)

     -i      Cause mv to write a prompt to standard error before moving a file that would overwrite an existing file.  If the response from the
	     standard input begins with the character 'y' or 'Y', the move is attempted.  (The -i option overrides any previous -f or -n options.)

     -n      Do not overwrite an existing file.  (The -n option overrides any previous -f or -i options.)

     -v      Cause mv to be verbose, showing files after they are moved.

     It is an error for either the source operand or the destination path to specify a directory unless both do.

     If the destination path does not have a mode which permits writing, mv prompts the user for confirmation as specified for the -i option.

     As the rename(2) call does not work across file systems, mv uses cp(1) and rm(1) to accomplish the move.  The effect is equivalent to:

	   rm -f destination_path && 
	   cp -pRP source_file destination && 
	   rm -rf source_file

DIAGNOSTICS

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

SEE ALSO

     cp(1), rm(1), symlink(7)

COMPATIBILITY

     The -n and -v options are non-standard and their use in scripts is not recommended.

STANDARDS

     The mv utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.

HISTORY

     A mv command appeared in Version 1 AT&T UNIX.
