I'm not terribly familiar with perl, but assuming the s/... works like normal sed: I would guess it's matching the entire 'ram' element @actiontext[2], but you're only replacing the 'ram' part with $2 (or actually nothing, for that match) - leaving the remainder of that element to be put into @action[1].

NAME
fc-match - match available fonts SYNOPSIS
fc-match [ -asvVh ] [ --all ] [ --sort ] [ --verbose ] [ [ -f format ] [ --format format ] ] [ --version ] [ --help ] [ pattern [ element... ] ] DESCRIPTION
fc-match matches pattern (empty pattern by default) using the normal fontconfig matching rules to find the best font available. If --sort is given, the sorted list of best matching fonts is displayed. The --all option works like --sort except that no pruning is done on the list of fonts. If any elements are specified, only those are printed. Otherwise short file name, family, and style are printed, unless verbose output is requested. OPTIONS
This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. -a Displays sorted list of best matching fonts, but do not do any pruning on the list. -s Displays sorted list of best matching fonts. -v Print verbose output of the whole font pattern for each match, or elements if any is provided. -f Format output according to the format specifier format. -V Show version of the program and exit. -h Show summary of options. pattern Displays fonts matching pattern (uses empty pattern by default). element If set, the element property is displayed for matching fonts.
