imp 7e6cabd06e Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

.Sh NAME
.Nm apply
.Nd apply a command to a set of arguments
.Sh SYNOPSIS
.Nm
.Op Fl a Ar c
.Op Fl d
.Op Fl #
.Ar command argument ...
.Sh DESCRIPTION
The
.Nm
utility runs the named
.Ar command
on each
argument
.Ar argument
in turn.
.Pp
Character sequences of the form
.Dq Li \&%d
in
.Ar command ,
where
.Sq Li d
is a digit from 1 to 9, are replaced by the
.Li d Ns \'th
following unused
.Ar argument .
In this case, the largest digit number of arguments are discarded for
each execution of
.Ar command .
.Pp
The options are as follows:
.Bl -tag -width indent
.It Fl #
Normally arguments are taken singly; the optional number
.Fl #
specifies the number of arguments to be passed to
.Ar command .
If the number is zero,
.Ar command
is run, without arguments, once for each
.Ar argument .
.Pp
If any sequences of
.Dq Li \&%d
occur in
.Ar command ,
the
.Fl #
option is ignored.
.It Fl a Ar c
The use of the character
.Sq Li %
as a magic character may be changed with the
.Fl a
option.
.It Fl d
Display the commands that would have been executed, but do not actually
execute them.
.El
.Sh ENVIRONMENT
The following environment variable affects the execution of
.Nm :
.Bl -tag -width SHELL
.It Ev SHELL
Pathname of shell to use.
If this variable is not defined, the Bourne shell is used.
.El
.Sh FILES
.Bl -tag -width /bin/sh -compact
.It Pa /bin/sh
default shell
.El
.Sh EXAMPLES
.Bl -tag -width apply -compact
.It Li "apply echo *"
is similar to
.Xr ls 1 ;
.It Li "apply \-2 cmp a1 b1 a2 b2 a3 b3"
compares the `a' files to the `b' files;
.It Li "apply \-0 who 1 2 3 4 5"
runs
.Xr who 1
5 times; and
.It Li "apply \'ln %1 /usr/joe\'" *
links all files in the current directory to the directory
.Pa /usr/joe .
.El
.Sh HISTORY
The
.Nm
command appeared in
.Bx 4.2 .
.Sh AUTHORS
.An Rob Pike
.Sh BUGS
Shell metacharacters in
.Ar command
may have bizarre effects; it is best to enclose complicated
commands in single quotes
.Pq '' .
.Pp
The
.Nm
utility does not recognize multibyte characters.
