+.Sh NAME
+.Nm install
+.Nd install binaries
+.Sh SYNOPSIS
+.Nm install
+.Op Fl cs
+.Op Fl f Ar flags
+.Op Fl g Ar group
+.Op Fl m Ar mode
+.Op Fl o Ar owner
+.Ar file1 file2
+.Nm install
+.Op Fl cs
+.Op Fl f Ar flags
+.Op Fl g Ar group
+.Op Fl m Ar mode
+.Op Fl o Ar owner
+.Ar file1
+\&...
+.Ar fileN directory
+.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.
+This flag turns off the default behavior of
+.Nm install
+where it deletes the original file after creating the target.
+.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.
+.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.
+.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.
+.El
+.Pp
+By default,
+.Nm install
+preserves all file flags, with the exception of the ``nodump'' flag.
+.Pp
+The
+.Nm install
+utility attempts to prevent moving a file onto itself.
+.Pp
+Installing
+.Pa /dev/null
+creates an empty file.
+.Pp
+Upon successful completion a value of 0 is returned.
+Otherwise, a value of 1 is returned.
+.Sh SEE ALSO
+.Xr chflags 1 ,
+.Xr chgrp 1 ,
+.Xr chmod 1 ,
+.Xr cp 1 ,
+.Xr mv 1 ,
+.Xr strip 1 ,
+.Xr chown 8
+.Sh HISTORY
+The
+.Nm install
+utility appeared in
+.Bx 4.2 .
