Teaching Notes

A little note about typographic conventions you'll see here

If you see something that looks a bit like

• ls -l

It is likely a command line. You can triple-click it & paste it directly into a terminal.

If there is a part that's ALL-CAPS & BOLD, this is a part of the command line you'll probably need to edit for your particular useage.

i.e.:

• cp FOO.BAR FOO.BAR.bak

Sometimes, there'll be whole scripts to paste into a file on your machine. (I like vi as an editor, but use whatever editor you like.) When a scrip is posted, it'll be formatted like this:

# This is a rather silly little bash script...

echo "This script is silly."
echo "It doesn't do much."
echo
echo "In fact, it just tells you it's silly..."

Just copy the whole thing & paste it into your editor in a terminal...

The actual lessons

• ssh - Remote control of Linux machines
• scp - copying files between machines securely
• rsync - Copying files (including remotely) with a bunch of control
• systemctl - Managing services
• vi - Editing files... on damn near ANY Linux machine

How to SQL
