.Nm

copies
|

.Ar source
|

.Ar dest .
|
||||
If more than one
|
||||
.Ar source
|
||||
is given
|
||||
.Ar dest
|
||||
has to be a directory.
|
||||
.Nm
|

can also change the attributes of the copies.
|

.Sh OPTIONS
|

.Bl -tag -width Ds
|

.It Fl d
|
||||
Create the directories
|
||||
.Ar dir .
|
||||
.It Fl D
|
||||
Create missing parent directories to
|
||||
.Ar dest .
|
||||
If
|
||||
.Fl t
|
||||
is used, the
|
||||
.Ar dest
|
||||
itself is also created if missing.
|
||||
.It Fl g Ar group
|
||||
Change the installed files' group to
|
||||
.Ar group .
|
||||
This may be a group name or a group identifier.
|
||||
.It Fl m Ar mode
|
||||
Change the file modes. Both numerical and symbolic
|
||||
values are supported. See
|
||||
.Xr chmod 1
|
||||
for the syntex.
|
||||
Default mode 0755. If a file has the mode 0644 and
|
||||
is copied with
|
||||
.It Fl o Ar owner
|
||||
Change the installed files' owner to
|
||||
.Ar owner .
|
||||
This may be a user name or a user identifier.
|
||||
.It Fl s
|
||||
Remove unnecessary symbols using
|
||||
.Xr strip 1 .
|
||||
Failure to strip a file does not imply failure to install the file.
|
||||
.It Fl t Ar dest
|
||||
Copy files into the directory
|
||||
.Ar dest .
|
||||
.Nm install ,
|
||||
the copy's mode will be 0755 unless
|
||||
.Fl m
|
||||
is used to select another mode. When the symbolic
|
||||
notation is used, the base mode is 0000.
