Useful Linux Tricks
On the computer console, Shift-Page Up and Shift-Page Down can be used to scroll through the last 6 or so
screenfuls of text. Each keystroke scrolls forward and back by half of a screen.
The TM-2000/MTM-2000 is configured with 2 virtual consoles. Normally, everything is done on the first virtual
console. However, Alt-F2 can be used to switch to a second virtual console (the first time you do this, you will
be at another login prompt); Alt-F1 can be used to switch back to the first virtual console. This can be useful if
you are logged in and doing something, and need to look something up without disturbing your first session.
The computer can be rebooted by typing Control-Alt-Del. You do not have to be logged in to do this. Alterna-
tively, if you are logged in as
root, you can type the command “shutdown -r0”. To halt the computer, rather than
reboot it, type the command shutdown -h0”, and wait for the “Power down.” message to appear.
If you are logged in, you can log out by typing the command “exit”, or by pressing Ctrl+D.
If the computer is restarted without shutting it down properly (e.g. there is power failure), the computer will
automatically run
fsck (“file system check”, similar to DOS’s chkdsk). However, this will normally only take a
few seconds, since there is not that much data stored on the hard disk.
