SecureCRT uses the Ctrl+Ins and Shift+Ins keys for copy and paste instead of the normal windows defaults of Ctrl+C / V. The reason why this is done is because most unix or linux varieties use those keys as part of the shell.
The default shell on most Linux operating systems is called Bash. There are a couple of important hotkeys that you should get familiar with if you plan to spend a lot of time at the command line. These shortcuts will save you a ton of time if you learn them.
If you are running Ubuntu Server, or even if you prefer to administer your desktop from the command line, you will want to be able to see what packages are available for update. Ubuntu includes a great package management tool called Aptitude that gives you an interactive environment from which to install/upgrade packages.
The package management system on Ubuntu makes it extremely simple to install and remove packages, but sometimes it’s important to figure out what version of a particular package that you actually have installed.

When you are using a linux system, it’s useful to find out what groups you belong to, so you can understand whether you have access to files and directories. This is one of the simplest commands possible. I’m using Ubuntu linux, but this command should work on most varieties of linux.
Screen is like a window manager for your console. It will allow you to keep multiple terminal sessions running and easily switch between them. It also protects you from disconnection, because the screen session doesn’t end when you get disconnected.
If you install Ubuntu from a cd-rom, when you try to use apt-get to install new software it will prompt you for the cdrom every time. Kinda frustrating!
Ubuntu Server has the native ability to run multiple console sessions from the server console prompt. If you are working on the actual console and are waiting for a long running command to finish, there’s no reason why you have to sit and wait… you can just open another console and keep working.
When you are on the Ubuntu server console, you will invariably run commands that scroll past too far to see them on the screen. Since you aren’t in X, there’s no scrollbar for you to use to look back.
If the Ubuntu Server installer has set your server to use DHCP, you will want to change it to a static IP address so that people can actually use it.
If you’ve installed your Ubuntu installation with DHCP, it’s really easy to reconfigure your system to use a static IP address with the GUI based Network Settings dialog.
Ubuntu has a trash can/recycle bin feature similar to windows. The difference with Ubuntu is that you can empty the trash from the command line.
The Ubuntu file browser does not show hidden files or folders by default, only the files that your user has access to.
If you are running an Ubuntu guest in VMware, you may have found that you cannot switch into the Console mode using Ctrl+Alt+F1. If you try, you will encounter a blank screen and won’t see a login prompt at all.
KDE is an alternate window manager/desktop that can be installed on Ubuntu, and comes standard with the Kubuntu linux version. KDE is a lot more robust than Ubuntu’s Gnome environment, and is well worth a try if you haven’t used it.
