NAME

pkg_subst — substitute variables' values in files

SYNOPSIS

DESCRIPTION

pkg_subst is used within the ports tree to substitute variable values, using the exact same conventions used by pkg_create(1). Constructs like ${VAR} will be replaced with the variable value, according to -D name=value options.

The options are as follows

-c

Copy and substitute. Number of file arguments must be even. They are paired as src1 dest1, src2 dest2 ... and each src file is substituted and copied into the corresponding dest file .

-D name=value

Define name to value.

-g group

Change group of destination file to group.

-m mode

Change mode of destination file to mode.

-o owner

Change owner of destination file to owner.

If no file arguments is given, pkg_subst acts as a filter from stdin to stdout.

Without -c, each file is backed up as file.beforesubst before the substitution occurs.
