In a regular expression (RE) the ^ means the beginning of the line; together with the = it enforces an exact match. Omit the ^ and it must only end with the given pattern.

$1 ~ /.*(NAME$|DIR$|PATH$)/ is correct, because the $1 field is = delimited, and in a RE the $ enforces the end of the field. The .* means any characters but is not needed here because any leading characters are always permitted in a RE (unless there is a ^ anchor). So it is optimized $1 ~ /NAME$|DIR$|PATH$/ or with a common $ anchor $1 ~ /(NAME|DIR|PATH)$/.

mm-common-prepare

MM-COMMON-PREPARE(1)						  mm-common 0.9.5					      MM-COMMON-PREPARE(1)

NAME

       mm-common-prepare - Prepare a C++ binding module to use mm-common

SYNOPSIS

       mm-common-prepare [OPTION]... [SOURCE-DIR]

DESCRIPTION

       Run  mm-common-prepare to install the mm-common build support files into the source tree of a C++ binding module.  The exact location where
       these files will be installed can be influenced through special macros in the configure.ac file.

       AC_CONFIG_AUX_DIR([AUX-DIR])
	      The Automake include files are placed into the AUX-DIR subdirectory of the top-level source directory.  If AC_CONFIG_AUX_DIR is  not
	      specified, the files are placed at the top-level of the module's source tree.

       MM_CONFIG_DOCTOOL_DIR([DOCTOOL-DIR])
	      If the MM_CONFIG_DOCTOOL_DIR macro is called with an explicit DOCTOOL-DIR argument, the common utilities required for generating and
	      installing the reference documentation of a C++ binding module will be installed into the  named	subdirectory.	If  MM_CONFIG_DOC-
	      TOOL_DIR	is not used or does not specify a DOCTOOL-DIR argument, mm-common-prepare will not install the documentation utility files
	      into the module's source tree.  Instead, it is assumed that the module depends on glibmm and can	use  the  installed  documentation
	      utilities that come with it.

       If no SOURCE-DIR argument has been specified on the command line, the current working directory will be used.

OPTIONS

       -c, --copy
	      copy files instead of creating symbolic links to them

       -f, --force
	      forcefully replace existing files or symbolic links

       --help display a help message and exit

       --version
	      show version information and exit

EXIT STATUS

       The exit status is 0 if OK, or 1 if an error occurred.

FILES

       The build support files currently installed by mm-common-prepare are listed below.

       Automake include files installed into AUX-DIR:
	      compile-binding.am
	      dist-changelog.am
	      doc-reference.am
	      generate-binding.am

       Documentation utilities installed into DOCTOOL-DIR:
	      doc-install.pl
	      doc-postprocess.pl
	      doxygen.css
	      tagfile-to-devhelp2.xsl
