I've been a systems administrator of one form or another for 19 years, spend 2-3 hours a day on the CLI, and I've never heard of ack. Depending on the time of day (and platform) i might use grep or egrep. I hopped onto one of the random ubuntu boxes I own, did a quick "apt-get install ack; man ack" - here is what it said:
"ACK is a highly versatile Kanji code converter. ACK can do reciprocal conversion among Japanese EUC"
This is probably why I don't use ack - never heard of it, not available on any system I use, and the dpkg repository has something that has nothing to do with grep.

Enough of an answer?
