.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 install
|
|
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.

|
|
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.

|
preserves all file flags, with the exception of the ``nodump'' flag.

.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.
