commandlinefu.com is the place to record those command-line gems that you return to again and again.
Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.
You can sign-in using OpenID credentials, or register a traditional username and password.
First-time OpenID users will be automatically assigned a username which can be changed after signing in.
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.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:
Once you've made the snapshot you can resume any stopped services and then back up the file system (using the snapshot) without having to worry about changed files.
When finished, the snapshot can be removed :
mdconfig -d -u 1
rm /var/.snap/snap_var_`date "+%Y-%m-%d"`
To monitor .vmdk files during snapshot deletion (commit) on ESX only (ESXi doesn't have the watch command):
1. Navigate to the VM directory containing .vmdk files.
# watch "ls -tough --full-time *.vmdk"
-t sorts by modification time
-o do not list group information (to narrow the output)
-u sorts by access time
-g only here for the purpose to easily remember the created mnemonic word 'tough'
-h prints sizes in human readable format (e.g., 1K 234M 2G)
--full-time sets the time style to full-iso and does not list user information (to narrow the output)
optionally useful parameters to the watch command:
-d highlight changes between updates
-n seconds to wait between updates (default is 2)
-t turn off printing the header
