DESCRIPTION
     The file(s) are copied (or linked if the -l option is specified) 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 permissions allow; an alternate backup suffix may
     be specified via the -B option's argument.

     -a command
             Run command on the target after installation and stripping (-s),
             but before ownership, permissions or timestamps are set and
             before renaming (-r) occurs.  command is invoked via the sh(1)
             shell, allowing a single -a argument be to specified to install
             which the shell can then tokenize.

     -b      Backup any existing files before overwriting them by renaming
             them to file.old. See -B for specifying a different backup suf-
             fix.

     -B suffix
             Use suffix as the backup suffix if -b is given.  If suffix con-
             tains a '%' sign, a numbered backup will be performed, and the
             %-pattern will be expanded using sprintf(3), given an integer
             counter as the backup number.  The counter used starts from 0,
             and the first available name resulting from the expansion is
             used.

     -c      Copy the file.  This is the default behavior; the flag is main-
             tained for backwards compatibility only.

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

     -D destdir
             Specify the DESTDIR (top of the file hierarchy) that the items
             are installed in to.  If -M metalog is in use, a leading string
             of ``destdir'' will be removed from the file names logged to the
             metalog.  This option does not affect where the actual files are
             installed.

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

     -g group
             Specify a group.

     -h hash
             When copying, calculate the digest of the files with hash to
             store in the -M metalog.  Supported digests:

                   none    No hash.  This is the default.

                   md5     The MD5 cryptographic message digest.

                   rmd160  The RMD-160 cryptographic message digest.

                   sha1    The SHA-1 cryptographic message digest.

     -l linkflags
             Instead of copying the file make a link to the source.  The type
             of the link is determined by the linkflags argument.  Valid
             linkflags are: a (absolute), r (relative), h (hard), s (sym-
             bolic), m (mixed).  Absolute and relative have effect only for
             symbolic links.  Mixed links are hard links for files on the same
             filesystem, symbolic otherwise.

     -M metalog
             Write the metadata associated with each item installed to metalog
             in an mtree(8) ``full path'' specification line.  The metadata
             includes: the file name and file type, and depending upon other
             options, the owner, group, file flags, modification time, and
             tags.

     -m mode
             Specify an alternative 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.

     -N dbdir
             Use the user database text file master.passwd and group database
             text file group from dbdir, rather than using the results from
             the system's getpwnam(3) and getgrnam(3) (and related) library
             calls.

     -o owner
             Specify an owner.

     -p      Preserve the source files access and modification times.

     -r      Install to a temporary file and then rename the file to its final
             destination name.  This can be used for precious files, to avoid
             truncation of the original when error conditions (filesystem full
             etc.) occur.

     -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.  If the environment variable STRIP is set, it is used as
             the strip(1) program.

     -S stripflags
             install passes stripflags as option arguments to strip(1).  When
             -S is used, strip(1) is invoked via the sh(1) shell, allowing a
             single -S argument be to specified to install which the shell can
             then tokenize.  Normally, install invokes strip(1) directly.
             This flag implies -s.

     -T tags
             Specify the mtree(8) tags to write out for the file when using -M
             metalog.

     -U      Indicate that install is running unprivileged, and that it should
             not try to change the owner, the group, or the file flags of the
             destination.  The information that would have been updated can be
             stored in a log file with -M metalog.

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

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

     Installing /dev/null creates an empty file.

EXIT STATUS
     The install utility exits 0 on success, and >0 if an error occurs.

ENVIRONMENT
     STRIP       The program used to strip installed binaries when the -s
                 option is used.  If unspecified, /usr/bin/strip is used.

SEE ALSO
     chflags(1), chgrp(1), chmod(1), cp(1), mv(1), strip(1), chown(8),
     mtree(8)
