Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Creates a full snapshot of your current vim session, including tabs, open buffers, cursor positions, everything. Can be resumed with vim -S . Useful for those times when you HAVE to close vim, but you don't want to lose all your hard-opened buffers and windows. The ! will cause vim to overwrite the file if it already exists. It is not necessary, but useful if you frequently save to the same file (like session.vim or something).

* Adjust the find command to your own filters.

I save this to bin/iptrace and run "iptrace ipaddress" to get the Country, City and State of an ip address using the http://ipadress.com service.

I add the following to my script to get a tinyurl of the map as well:

URL=`lynx -dump http://www.ip-adress.com/ip_tracer/?QRY=$1|grep details|awk '{print $2}'`

lynx -dump http://tinyurl.com/create.php?url=$URL|grep tinyurl|grep "19. http"|awk '{print $2}'
