* Fear of the command line often means, fear of typing too much. Everybody fears this, so there are tools.
* Tab completion is probably the most important tool, and relies on your pressing the <code>TAB</code> key
* It tries to complete the filename or program name you have started typing, saving you typing time and reducing spelling errors.
cd kir
* followed by <code>TAB</code>. If there is only one directory with a name starting with the letters "kir", the rest of the name will be completed for you.
* if there are several options, you need to supply more "hint-letters" and press <code>TAB</code> multiple times.

== Exercises ==

* Type <code>ls testseq</code> and use tab completion.
* This will show you a list of files that start with testseq.
* You now have the option of completing the filename yourself, or "tabbing" through the filenames available.
* It limits itself to files in your current directory.
* What happens if you type <code>TAB</code> immediately after <code>ls</code>?
* How can you find out all commands available on the system?

== Answer ==
* The first word of a command line is usually a command, so TAB looks for commands, not files.
* By giving no hints at all to TAB, it will look for all possible commands.
