+
+At the end of this tutorial, you will be able to,
+
+ 1. Understand various features of shell
+ #. Learn about shell meta characters

+
+{{{ Switch to the pre-requisite slide }}}
+
+.. R3
+
+Before beginning this tutorial,we would suggest you to complete the 
+former tutorials as being displayed currently.
+
+.. L4
+
+{{{ Show slide, with Tab-completion }}} 
+
+.. R4
+
+The Bash shell has some nice features, that make our job of using the shell 
+easier and much more pleasant. We shall look at a few of them, here.
+
+
+Bash provides the feature of tab completion. What does tab completion mean? 
+When you are trying to type a word, bash can complete the word for you, if you 
+have entered enough portion of the word (to complete it unambiguously) and 
+then hit the tab key.
+
+If on hitting the tab key, the word doesn't get completed, either the word 
+doesn't exist or the word cannot be decided unambiguously. If the case is the 
+latter one, hitting the tab key a second time, will list the possibilities.
+
+.. L5
+
+{{{ Show slide, with Tab-completion.. }}} 
+
+.. R5
+
+Bash provides tab completion for the following.
+
+        File Names
+        Directory Names
+        Executable Names
+        User Names (when they are prefixed with a ~)
+        Host Names (when they are prefixed with a @)
+        Variable Names (when they are prefixed with a $)
+
+.. R6
+
+For example,
+
+.. L6
+
+{{{ Switch to terminal }}}
+::
+
+
+    pas<TAB><TAB>
+    PA<TAB>
+    ~/<TAB><TAB>
+
+.. L7
+
+{{{ Show slide, with History }}}
+
+.. R7
+
+Bash also saves the history of the commands you have typed. So, you can go 
+back to a previously typed command. Use the up and down arrow keys to navigate 
+in your bash history.
+You can also search incrementally, for commands in your bash history. Ctrl-r 
+search for the commands that you have typed before. But, note that the number 
+of commands saved in the history is limited, generally upto a 1000 commands.
+
+.. L8
+
+{{{ Switch to terminal }}}
+::
+
+    <Ctrl-r> pas
+
+.. R8
+
+.. L9
+
+{{{ Show slide, with Shell Meta Characters }}} 
+
+.. R9
+
+Unix recognizes certain special characters, called "meta characters," as 
+command directives. The shell meta characters are recognized anywhere they 
+appear in the command line, even if they are not surrounded by blank space. 
+For that reason, it is safest to only use the characters A-Z, a-z, 0-9, and 
+the period, dash, and underscore characters when naming files and directories
+ on Unix. If your file or directory has a shell meta character in the name, 
+you will find it difficult to use the name in a shell command.
+
+The characters that you see on the slide are the shell meta characters
+
+ / < > ! $ % ^ & * | { } [ ] " ' ` ~ ;
+
+.. R10
+
+Let's take an example,
+
+.. L10
+
+{{{ Switch to terminal }}} 
+::
+
+    ls file.*
+
+.. R11
+
+It means, run on a directory containing the files file, file.c, file.lst, and 
+myfile would list the files file.c and file.lst. However,
+
+.. L11
+
+::
+
+    ls file.?
+
+.. R12
+
+Run on the same directory would only list file.c because the ? only 
+matches  one character, no more, no less. This can save you a great deal of 
+typing time.
+
+For example, if there is a file called california_cornish_hens_with_wild_rice 
+and no other files whose names begin with 'c', you could view the file without 
+typing the whole name by typing this
+
+.. L12
+
+::
+
+    more c*
+
+.. R13
+
+Here, the c* matches that long file name.
+
+File-names containing metacharacters can pose many problems and should never 
+be intentionally created.

+
+This brings us to the end of the end of this tutorial.
+In this tutorial, we have learnt to,
+
+1. Implement features of tab-completion and history.
+#. Make use of the shell meta characters.
+ 
+.. L15
+ 
+{{{ Show self assessment questions slide }}}
+
+.. R15
+
+Here are some self assessment questions for you to solve:
+
+1. Bash does not provide tab completion for Host Names. True of False?
+
+2. State the command which will list all the files in the current working 
+   directory that end in either .c or .h
+
+.. L16
+
+{{{ Solutions for the self assessment questions on slide }}}
+
+.. R16
+
+And the answers:
+
+1. False. Bash provides tab completion for Host Names when they are prefixed 
+   with a @ sign.
+
+  
+2. The command which will find the files ending either in .c or .h is,
+::
+
+    ls *.[ch]
