Two of the tricks he lists is X forwarding with SSH, and using the SSH fuse filesystem. Both of which I use on a daily basis.

Check it out here.

:%s/[ \t]/./

And here’s how to remove all trailing spaces at the end of each line:

:%s/\s\+$//

Have any more vim quick tips? Let’s hear them in the comments.

find /home/foo/* -mtime +5 -exec echo {} > oldfiles.txt \;
&& mail -s "files older than 5 days" foo@foogazi.com < oldfiles.txt

This command searches for files that are older than 5 days, and sends the output to oldfiles.txt, then an email is sent to foo@foogazi.com with a list of the old files.

Alternatively, you could search for files older than 5 days, then delete them using this command:

find /home/foo/* -mtime +5 -exec rm {} \;

Here is a quick write up on how to reset your gnome settings in Ubuntu.

In short, you basically need to delete these from your home directory: ~/.gnome ~/.gnome2 ~/.gconf ~/.gconfd ~/.metacity

Typically, Linux runlevels look like the following:

  • 0 – Halt (shutdown)
  • 1 – Single-User mode
  • 2-5 – Full multi-user mode with console logins and display manager if it’s installed
  • 6 – Reboot

On most Linux servers, the default runlevel will be set to runlevel 3. Multi-user mode and console logins only.  Whereas, most Linux desktops, the default runlevel will be set to runlevel 5.

If you want to boot into a specific runlevel every time your computer turns on, all you need to do is edit the /etc/inittab. For this example, we will change the runlevel from 3 to 5.

# vi /etc/inittab

Modify the line that looks like this:

id:3:initdefault:

And change the number 3, to 5.

id:5:initdefault:

Save the file.  Next time you reboot Linux will boot directly into your desktop window manager.

I’ve used Lucky Backup in the past and can attest that it is very easy to use, and has all the features you need for a good backup system.

Some of the features include:

  • Snapshot backups
  • Sync directories
  • Exclude directories/files
  • Profiles
  • Scheduling
  • Logging
  • Command line mode

Head over and read Jack’s how to. He does a great job showing just how easy it is to use.

For most people using Ubuntu Karmic (9.10) or newer, installation should be very simple:

  • sudo apt-get install python-gdata
  • [download .deb package]
  • sudo dpkg -i googlecl*.deb

Here are some example scripts:

  • google calendar add "Dinner party with George today at 6pm" # add event to calendar
  • google calendar today # List events for today only.
  • google calendar list --date 2010-06-01,2010-06-30 # List events.
  • google calendar delete --title "Dinner party with George" # Delete an event.

  • google contacts add "J. Random Hacker, jrandom@example.com"
  • google contacts list name,email --title "J. Random Hacker"
  • google contacts delete --title "J. Random Hacker"

The possibilities of GoogleCL are definitely going to expand, and I can already think of some useful ways to incorporate these into some scripts of mine.

6) Ubuntu is safer than Microsoft Windows The vast majority of viruses and spyware written by hackers are not designed to target and attack Linux.

Today, if you visit the same Dell.com/Ubuntu, you’ll see the following change:

6) Ubuntu is secure According to industry reports, Ubuntu is unaffected by the vast majority of viruses and spyware.

Pretty comical huh?  Many of us in the Linux industry are claiming that this is probably an evil doing of Microsoft pressuring Dell to ‘correct’ the statement.  Which, really, would not surprise me the least bit.

I suppose I understand why Dell changed their tune, but in actuality, the first statement was nothing but a simple true fact.

What do you guys think?  Should Dell have kept their ground?
