This comes in very handy.
To get a log slice from a given date to the end:
# sed -n '/15\/Nov\/2010/,$ p' /path/to/access_log
Or, get a log slice in a given date range:
# sed -n '/5\/Nov\/2010/,/5\/Dec\/2010/ p'
/path/to/access_log
Do something like this to filter and sort the results:
# awk '{print $2,$6}' access_log | sort -fr
