Flushing a running memcached instanceEdit

In the past I’ve resorted to a heavy-handed sudo /etc/init.d/memcached restart (or similar, depending on platform), but you can also do it with telnet:

$ telnet localhost 11211
flush_all

Or if you don’t have telnet (likely the case if you are on recent macOS):

echo flush_all | nc -w 2 localhost 11211
