NAME

       install - install binaries

SYNOPSIS

       install [-cs] [-f flags] [-g group] [-m mode] [-o owner] file1 file2

       install [-cs] [-f flags] [-g group] [-m mode] [-o owner] file1 ... fileN directory

DESCRIPTION

       The  file(s)  are  moved (or copied if the c option is specified) to the target file or directory.  If the destination is a directory, then
       the file is moved into directory with its original filename.  If the target file already exists, it is overwritten if permissions allow.

       c       Copy the file.  This flag turns off the default behavior of install where it deletes the original file after creating the target.

       f       Specify the target's file flags.  (See chflags(1) for a list of possible flags and their meanings.)

       g       Specify a group.

       m       Specify an alternate mode.  The default mode is set to rwxr-xr-x (0755).  The specified mode may be either  an  octal  or  symbolic
	       value; see chmod(1) for a description of possible mode values.

       o       Specify an owner.

       s       Install	exec's	the  command  strip(1) to strip binaries so that install can be portable over a large number of systems and binary
	       types.

       By default, install preserves all file flags, with the exception of the ``nodump'' flag.

       The install utility attempts to prevent moving a file onto itself.

       Installing /dev/null creates an empty file.

       Upon successful completion a value of 0 is returned.  Otherwise, a value of 1 is returned.

NAME

     install -- install binaries

SYNOPSIS

     install [-bCcMpSsv] [-B suffix] [-f flags] [-g group] [-m mode] [-o owner] file1 file2
     install [-bCcMpSsv] [-B suffix] [-f flags] [-g group] [-m mode] [-o owner] file1 ... fileN directory
     install -d [-v] [-g group] [-m mode] [-o owner] directory ...

DESCRIPTION

     The file(s) are copied to the target file or directory.  If the destination is a directory, then the file is copied into directory with its
     original filename.  If the target file already exists, it is either renamed to file.old if the -b option is given or overwritten if permis-
     sions allow.  An alternate backup suffix may be specified via the -B option's argument.

     The options are as follows:

     -B suffix
	     Use suffix as the backup suffix if -b is given.

     -b      Back up any existing files before overwriting them by renaming them to file.old.  See -B for specifying a different backup suffix.

     -C      Copy the file.  If the target file already exists and the files are the same, then don't change the modification time of the target.

     -c      Copy the file.  This is actually the default.  The -c option is only included for backwards compatibility.

     -d      Create directories.  Missing parent directories are created as required.

     -f      Specify the target's file flags; see chflags(1) for a list of possible flags and their meanings.

     -g      Specify a group.  A numeric GID is allowed.

     -M      Disable all use of mmap(2).

     -m      Specify an alternate mode.  The default mode is set to rwxr-xr-x (0755).  The specified mode may be either an octal or symbolic
	     value; see chmod(1) for a description of possible mode values.

     -o      Specify an owner.	A numeric UID is allowed.

     -p      Preserve the modification time.  Copy the file, as if the -C (compare and copy) option is specified, except if the target file
	     doesn't already exist or is different, then preserve the modification time of the file.

     -S      Safe copy.  Normally, install unlinks an existing target before installing the new file.  With the -S flag a temporary file is used
	     and then renamed to be the target.  The reason this is safer is that if the copy or rename fails, the existing target is left
	     untouched.

     -s      install exec's the command strip(1) to strip binaries so that install can be portable over a large number of systems and binary
	     types.

     -v      Causes install to show when -C actually installs something.

     By default, install preserves all file flags, with the exception of the ``nodump'' flag.

     The install utility attempts to prevent moving a file onto itself.

     Installing /dev/null creates an empty file.

DIAGNOSTICS

     The install utility exits 0 on success, and 1 otherwise.

FILES

     INS@XXXX  If either -S option is specified, or the -C or -p option is used in conjuction with the -s option, temporary files named INS@XXXX,
	       where XXXX is decided by mkstemp(3), are created in the target directory.

COMPATIBILITY

     Historically install moved files by default.  The default was changed to copy in FreeBSD 4.4.

HISTORY

     The install utility appeared in 4.2BSD.

BUGS

     Temporary files may be left in the target directory if install exits abnormally.

     File flags cannot be set by fchflags(2) over a NFS file system.  Other file systems do not have a concept of flags.  install will only warn
     when flags could not be set on a file system that does not support them.

     install with -v falsely says a file is copied when -C snaps hard links.
