Trying Out Commands
Opening a terminal

- Inside this window, you are actually running the famous linux-shell, in this case bash.
- Most of the time, linux user type text commands in a shell like this.
let't try this out.
Running commands
- Most people try this well-known linux command:
1ls
It will show a list of the files.
- This is not something that is part of the shell!
This is the linux philosophy: The ls command is actually a program you have just run. - Now try:
1ls -l
The parameter l is preceded with a dash, and specify long listing of files.
Let's add another parameter, a, that instructs ls to show us hidden files (files with names starting with a dot).
You can also comnine both parameters.
Here are the two versions:
1ls -l -a
2ls -la
