Mac OS X for Windows users

Mac OS X is supposed to be more friendly than Windows, so you should get used to it pretty fast.
There is a @ sign somewhere on the bottom right, click on that to find more about Mac OS.

Window manipulation

- the three coloured buttons on the left-top of the window do closing (red), minimizing (yellow) and maximizing (green)
- changing the size of the window: right-bottom
- unlike Windows, each application has its menu on top of the screen, instead of on top of the window. When you switch between applications, the menu changes (except for the apple in the top-left, which is the system menu).
- closing the window of an application generally will _not_ close the application. you have to press Meta-Q or chose File/Quit in the application menu
- you cannot close the Finder (the file explorer)
- to log out, use the system (apple) menu on the top left or press Meta-Shift-Q

Exploring files

- to see what is on the local disk click on the harddisk under the clock (top right)
- click on  the "home" on the right under the harddisk (and under AFS)  to see your own files (accessible from all CSC unix machinnes, either solaris or Mac OS X)

Graphic applications

- on the local disk, go to Applications, then Utilities
- you can drag from the file explorer (called Finder on Mac) any applications that you will use often on the bar at the bottom of the screen
- you may feel you have problems with the Mac keys. A good application for that is the Key Caps which you can find in Utilities
- an important key on the Mac is the Meta key (the two keys near the spacebar)
- to switch between applications, click on their windows, or press Meta-Tab (look at the application bar at the bottom), or  press the menu with the name of the application near the system (apple) menu on the top left

Terminal (Unix) applications

- you will need to run a number of applications in the Terminal (similar to Windows Command Prompt). Find the Terminal in Utilities
- You will need more than one terminal window. To open a new terminal window  use Meta-N or chose File/New Shell when Terminal is active
- The terminal, (and emacs below) have file name self completion. Just type the first 1-2 letters of a file name and press Tab, the name will be completed automatically.
- if you get lost in the file system directories, type cd ~  (cd space tilda) to come back to your home directory
- don't type the same command many times! You can press arrow-up or arrow-down to navigate through the previous commands that you gave.
- some unix file-related commands
  • cd dir to change directory
  • Tab while writing a file/directory name auto-completes it so you don't have to type it all
  • ls to list a directory (dir in Windows)
  • pwd prints the working directory
  • mkdir dir to make directories
  • rm filename to delete a file (del in Windows)
  • rmdir dirname to remove an empty directory
  • more filename  to view the contents of a text file (but better open it in emacs, see below)

Text editors

- up to now the best text editor for programming i could find on the Macs (or Windows) is emacs. Type "emacs" in the terminal
Emacs is not very friendly with  beginers but it's worth learning to use it. If you get to like it, there is emacs for Windows and for many other platforms.
    • ctrl-x ctrl-f to open a file (or create a new file), ctrl-x ctrl-s to save it, ctrl-x ctrl-w to "save as", ctrl-x ctrl-c to exit.
    • you can open more files (called buffers in emacs). ctrl-x b to switch to another buffer, ctrl-x k to close (kill) a buffer. ctrl-x ctrl-b to see all buffers, ctrl-x 1 to see just one buffer, ctrl-x 2 to see 2 buffers, etc. ctrl-x o to switch to the next visible buffer
    • Tab to align a program line nicely (in Java files)
    • ctrl-a to go to the beginning of the line, ctrl-e to go to the end of the line, ctrl-v one page down, esc v one page up
    • ctrl-d to delete the character to the right (Delete key on windows), ctrl-h to delete to the left (Backspace works as well)
    • ctrl-k to cut lines, ctrl-y to paste them
    • ctrl-s to search text. The search is incremental, you will like it.
    • whenever you get lost in emacs commands, just press Esc 3 or more times until it says "Quit". That means that you gave up whatever you wanted to do when you went wrong and now you can start new commands.
    • find out more about emacs. Here is the official site
- a simpler text editor is pico, it has on-screen help. Just type pico. You can only edit one file with pico so you will have to open more Terminal windows (Meta-n)

Logging in from home

You can use  KTelnet  to log in from home on any of the Simplex and Duplex machines (for example simplex-01.nada.kth.se, simplex-02,... simplex-16). Login on any mac, no matter on which you worked in the lab. Then you will be able to use the Mac as if you opened a terminal.  It is good practice to run the command kauth just after you logged in.
  • I am having problems using Backspace in emacs over KTelnet. Instead of pressing backspace, move to the left with the <- arrow and then press ctrl-d to delete to the right instead of deleting to the left.
