# export_chrome_history.sh
# 
# A script to dump a list of urls from Google Chrome's History 
# database on OS X. It should work on any *nix, but you'll need
# to edit the values of $input_file and $output_file.

# Change these values if your History file is somewhere else
# or if you want to export the history to somewhere else.

input_file="$HOME/Library/Application Support/Google/Chrome/Default/History"
output_file="$HOME/Library/Application Support/Google/Chrome/Default/chrome-history.txt"

# Use this to keep the size of the history under control

n_most_recent=500

# If Chrome.app is open, the History database will be locked. So 
# we'll make a temporary copy to play with.

tmp_history=`mktemp -u "/tmp/export_chrome_history.XXXXX" || exit 1`
cp "$input_file" "$tmp_history"

sqlite3 "$tmp_history" \
	"select url from urls order by last_visit_time desc" \
		| head -n $n_most_recent \
		> $output_file
rm "$tmp_history"

Here's a chrome extension I made that does this: https://chrome.google.com/webstore/detail/export-history/hcohnnbbiggngobheobhdipbgmcbelhh
