Site originally by David Winterbottom (user root).

Psst. Open beta.

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:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Show all detected mountable Drives/Partitions/BlockDevices

Yields entries in the form of "/dev/hda1" etc.

Use this if you are on a new system and don't know how the storage hardware (ide, sata, scsi, usb - with ever changing descriptors) is connected and which partitions are available.

Far better than using "fdisk -l" on guessed device descriptors.

Browse shared folder when you're the only Linux user

Under Ubuntu smbclient is part of the samba package. With the version I use (3.0.28a) cd-ing into folders with spaces in the name is a drag. You have to put the folder name in quotes:

smb: \Shared\> cd "Marketing and PR"

Refresh profile file

If you edit your .profile you need to refresh it for changes to take place. Simple way to refresh is logout and login. This command is the quickest way to do it.

If you're deleting some variables, they would not get nulled with this command but just removed.
