.Sh DESCRIPTION
The file(s) are moved (or copied if the
.Fl c
option is specified) to the target file or directory.
If the destination is a directory, then the
.Ar file
is moved into
.Ar directory
with its original filename.
If the target file already exists, it is overwritten if permissions
allow.
.Pp
.Bl -tag -width Ds
.It Fl C
Copy the file, as if the
.Fl c
option is specified,
except if the target file already exists and the files are the same,
then don't change the modification time of the target.
.It Fl c
Copy the file.
This flag turns off the default behavior of
.Nm
where it deletes the original file after creating the target.
.It Fl D
Print debugging information.
If
.Fl D
is specified one or more times,
then print the renaming steps for
.Fl C .
If
.Fl D
is specified two or more times,
then warn about files that aren't installed with
.Fl C .
.It Fl d
Create directories. 
Missing parent directories are created as required.
.It Fl f
Specify the target's file flags; see
.Xr chflags 1
for a list of possible flags and their meanings.
.It Fl g
Specify a group.
A numeric GID is allowed.
.It Fl M
Disable all use of
.Xr mmap 2 .
.It Fl 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
.Xr chmod  1
for a description of possible mode values.
.It Fl o
Specify an owner.
A numeric UID is allowed.
.It Fl p
Preserve the modification time.
Copy the file, as if the
.Fl 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.
.It Fl s
.Nm Install
exec's the command
.Xr strip  1
to strip binaries so that install can be portable over a large
number of systems and binary types.
.It Fl v
Causes
.Nm
to show when
.Fl C
acutally installs something.
.El
.Pp
By default,
.Nm
preserves all file flags, with the exception of the ``nodump'' flag.
.Pp
The
.Nm
utility attempts to prevent moving a file onto itself.
.Pp
Installing
.Pa /dev/null
creates an empty file.
.Sh DIAGNOSTICS
The
.Nm
utility exits 0 on success, and 1 otherwise.
.Sh FILES
.Bl -tag -width INS@XXXX -compact
.It Pa INS@XXXX
If the
.Fl C
or
.Fl p
option is used, then temporary files named INS@XXXX,
where XXXX is decided by
.Xr mkstemp 3 ,
are created in the target directory.
.El
.Sh SEE ALSO

.Sh HISTORY
The
.Nm
utility appeared in
.Bx 4.2 .
.Sh BUGS
Temporary files may be left in the target directory if
.Nm
exits abnormally.
.Pp
File flags cannot be set by
.Xr fchflags 2
over a NFS file system.  Other file systems do not have a concept of flags.
.Nm
will only warn when flags could not be set on a file system
that does not support them.
.Pp
.Nm
with
.Fl v
falsely says a file is copied when
.Fl C
snaps hard links.
