Tip #3 Keychain - Manage ssh keys

What

Instead of constantly starting up ssh-agent and ssh-add, it is possible to use "keychain" to manage your ssh keys.

Command Line

sudo apt-get install keychain

Edit File

You then should add the following lines to your ${HOME}/.bashrc or /etc/bash.bashrc:

keychain id_rsa id_dsa
# ~/.keychain/`uname -n`-sh

Tip #4 Check for and fix filesystem errors on boot

What

This little tip turns on filesystem check to run at boot. It will check for and fix errors (similar to windows chkdisk) but at the same time increase your boot time.

Edit File

Open /etc/default/rcS with your text editor of choice (root permissions needed) and change this line:

FSCKFIX=no

to

FSCKFIX=yes

Tip #5 Some Gnome & Nautilus Tricks

What

Gnome and its file manager, Nautilus, have some interesting, useful but hard to discover tricks built in. Among them:

Actions

• Dragging a file with middle mouse button will show a menu upon release, allowing you to select among "move", "copy", "link to" and "cancel". Similar to right-mouse drag in Windows.
• Alt-left drag in any window will let you move that window, without having to hunt for the title bar. Just click anywhere in a window while the Alt key is pressed, and you can move the window.
• Alt-middle drag allows you to resize a window without having to hunt for the edges of the window. Neat.
• Alt-right click anywhere in the window will bring up the window menu (the one that is usually located by pressing on the top left corner of the title bar).
• Double-clicking on the title bar will expand a window to full-screen.
  • This behaviour can be modified in System menu --> Preferences --> Windows. Look for the "Titlebar Action" section - the "roll up when double-clicked" version can be very useful to manage the palettes and toolbars of applications like the GIMP, Inkscape or Scribus.
• To add an item to your Places menu, as well as to the Places sidebar in Nautilus, navigate to that location in Nautilus, and choose Bookmarks>Add Bookmark.
