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 $1 ~ /(NAME|DIR|PATH)$/.

       --destdir DIR

       --copy Do not create symbolic links

       All  operation  modes  except --download (or its synonym --update) accept paths to package.xml files or .star files, including remote URLs.
       --download and --update accept names of packages, which will be searched in the current system or on smalltalk.gnu.org) or  URLs  to  pack-
       age.xml or .star files.

       Except in uninstall and list files mode, gst-package requires write access to the GNU Smalltalk image directory, and merges the XML package
       files on the command line with that file.

       The default target directory is /build/buildd-gnu-smalltalk_3.2.4-2-amd64-LVoFQd/gnu-smalltalk-3.2.4

       The full documentation for gst-package is maintained as a Texinfo manual.  If the info and gst-package programs are properly  installed	at
       your site, the command

	      info gst

       should give you access to the complete manual.
