This rewrite in perl blows the socks off the old shell script version for large searches: $ time ./pacsearch.perl ^.*$ >/dev/null real 0m0.836s user 0m0.593s sys 0m0.217s $ time pacsearch.sh ^.*$ >/dev/null real 1m53.818s user 1m16.818s sys 0m33.694s Functionality and output is identical to the old version with the exception of the old version's missing EOL after all the output. It should be a lot easier to add new things like the --color flag that has been a TODO at the top of the script for a long time. Signed-off-by: Dan McGee <dan@archlinux.org>
