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.

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:
Return the creation date of a file on ext2, 3, 4 filesystems, because stat command won't show it.
Useful on ubuntu, debian, and else
For slow flash memory (cheap thumb drive), ext4 is the fastest stable file system for all use cases with no relevant exception:
Since we can usually dispense with the benefits of a journal for this type of storage, this is a way to achieve the least awful I/O-speed.
Disabling the journal for an existing ext4 partition can be achieved using
tune2fs -O ^has_journal /dev/sdXN
Note that it is often recommended to format removable flash media with ext2, due to the lack of a journal. ext4 has many advantages over ext2 even without the journal, with much better speed as one of the consequences. So the only usecase for ext2 would be compatibility with very old software.
Find out the earliest installation time of a linux system by getting the / filesystem creation time. This example is only valid the os is installed on an ext2/3/4 filesystem.
Before doing this, back-up all data on any ext3 partitions that are to be converted to ext4.
After running previous command you MUST run fsck, is needed to return the filesystem to a consistent state.
fsck -pDf /dev/yourpartition
Edit /etc/fstab and change the 'type' from ext3 to ext4 for any partitions that are converted to ext4.
