Download whole contents of target web site by wget

Sometimes we can spend fun time to read man page of command line tools.
One day I noticed that wget(1) has much more option than I expected.
As the example below, we can recursively download target web site's contents.

# Using Safari as UA
TARGET_URL="http://example.com/"
USER_AGENT="Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/603.1.30 (KHTML, like Gecko) Version/10.1 Safari/603.1.30"

nohup wget -rkpc --no-clobber --limit-rate 2.5k \
--wait=0.5 --random-wait \
--user-agent="${USER_AGENT}" \
"${TARGET_URL}" &

This command is verified with GNU Wget 1.18 built on darwin15.5.0.

For more detail, online manual is available at Linux man page.
