Task 2: Elementary Commands

In this part, you will familiarize with some common linux commands. Here are some simple examples.

1. startx Open the Graphical User Interface on Unix computers.
2. passwd This command is used to change your password. You should change your password frequently. (Your TA says ``A password is like a toothbrush: choose a good one, don't share it with anyone, and change it at the first sign of wear.'' Use your favourite word in your mother tongue and type it in English)
3. ls List files and directories in your current working directory.
4. man Online help for the arguments given to it. Ex: $ man ls
5. rm Removes files and directories (with the -r switch). Use this with care. There is no concept of recycle bin (by default) in Linux.
6. cd This command changes the directory mentioned. For example, cd /tmp changes the current directory to /tmp.
7. mkdir This command makes a new directory in the current directory.
8. xdosemu This command invokes the DOS Emulation Engine which runs the dos programs. Proceed to the next task.

Experiment by issuing commands by typing the command followed by a space followed by &
