.Sh NAME
.Nm pkg_subst
.Nd substitute variables' values in files
.Sh SYNOPSIS
.Nm pkg_subst
.Op Fl ci
.Op Fl B Ar basedir
.Op Fl D Ar name Ns Op = Ns Ar value
.Op Fl g Ar group
.Op Fl m Ar mode
.Op Fl o Ar owner
.Op Ar file ...
.Sh DESCRIPTION
.Nm
is used within the ports tree to substitute variable values, using
the exact same conventions used by
.Xr pkg_create 1 .
Constructs like
.Li ${VAR}
will be replaced with the variable value, according to
.Fl D Ar name Ns Op = Ns Ar value
options.
.Pp
The options are as follows
.Bl -tag -width Dname[=value]xxx
.It Fl B Ar basedir
Specify a basedir in which we know file properties.
It is forbidden to copy files from elsewhere without
.Fl m Ar mode .
.It Fl c
Copy and substitute.
Number of
.Ar file
arguments must be even.
They are paired as
.Ar src1
.Ar dest1 ,
.Ar src2
.Ar dest2 ...
and each
.Ar src
file is substituted and copied into the corresponding
.Ar dest
file.
.It Xo
.Fl D
.Ar name Ns Op = Ns Ar value
.Xc
Define
.Ar name
to
.Ar value ,
or to 1 if no value is given.
.It Fl g Ar group
Change group of destination file to
.Ar group .
.It Fl i
Ignore changes to group or owner that failed.
.It Fl m Ar mode
Change mode of destination file to
.Ar mode .
.It Fl o Ar owner
Change owner of destination file to
.Ar owner .
.El
.Pp
If no
.Ar file
arguments is given,
.Nm
acts as a filter from stdin to stdout.
.Pp
Without
.Fl c ,
each
.Ar file
is backed up as
.Ar file.beforesubst
before the substitution occurs.
