This is a repository for my favorite scripts, regexes, commandlines, utilities, code snippets, tips, and other geeky things that might be useful to someone googling for an obscure solution some day. It’s also a place to share my thoughts about companies I’ve dealt with, my favorite lifehacks, observations of interesting human behavior, clever and/or evil marketing schemes I’ve run across, and anything else I feel compelled to write about.
search for a string in access log, extract only ip address from matching line, sort the list of ip’s and remove duplicates, output the [shortened] list…
for ip in `grep -i firefox /cygdrive/w/resin/log/access.log \
| grep -o “^[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}” \
| sort -u \
| wc -l`; \
do echo $ip; \
done
