| નમસ્તે મિત્રો,'''Case statement .''' પરનાં આ સ્પોકન ટ્યુટોરીયલમાં સ્વાગત છે.

|-
| 00:07
| આ ટ્યુટોરીયલમાં આપણે શીખીશું , ઉદાહરણ સાથે '''case statement''' નું મહત્વ ''case statement''' નું સિન્ટેક્સ.

|-
| 00:17
| આ ટ્યુટોરીયલના અનુસરણ માટે, તમને ''Shell Scripting''' ના સામાન્ય જ્ઞાન વિષે જાણકારી હોવી જોઈએ.

|-
|00:23
|જો નથી,તો સંબંધિત ટ્યુટોરિયલ્સ માટે, બતાવેલ અમારી વેબ સાઈટ પર જાઓ.

|-
| 00:29
| આ ટ્યુટોરીયલ માટે હું ઉપયોગ કરી રહી છું ''' Ubuntu Linux''' 12.04''' ઓપરેટિંગ સિસ્ટમ''' અને '''GNU BASH''' આવૃત્તિ 4.1.10

|-
| 00:39
| નોંધ લો પ્રેક્ટીસ માટે GNU Bash આવૃત્તિ 4 અથવા તેથી વધુનો આગ્રહ કરીએ છીએ.

|-
| 00:47
| બેશ શેલમાં બે પ્રકારના કન્ડીશનલ સ્ટેટમેંટ હોય છે. '''if statement''' અને '''case statement. '''

|-
| 00:56
| '''if-else statement''' ની જગ્યાએ વૈકલ્પિક રીતે '''Case statement '' વાપરી શકાય છે.

|-
|01:03
|The '''case statement''' is preferred when there are many items to select from.

|-
|01:09
|It is usually used to implement '''menus''' in a script.

|-
| 01:14
|Let us see the syntax.

|-
|01:15
|'''case space $(dollar)VARIABLE space in''' '''match_1''' close round brackets space '''commands''' and semicolon twice

|-
|01:27
|'''match_n''' close round bracket space '''commands''' and semicolon twice '''asterisk''' close round bracket space '''command_to_execute_by_default''' and semicolon twice '''esac'''

|-
| 01:45
| The '''VARIABLE '''is compared to '''match_1.'''

|-
|01:48
|If it does not match, it moves on to the next case which is '''match_n.'''

|-
|01:54
|It will check if any one of these strings matches '''VARIABLE. '''

|-
|02:01
|If yes, then all the commands until the double''' semicolon (;;) '''are executed.

|-
| 02:07
| If neither match''' VARIABLE''', the commands associated with the '''asterisk '''are executed.

|-
| 02:14
|It is the default '''case '''condition because the '''asterisk '''will match all strings.

|-
| 02:21
|'''esac''' marks the end of '''case block.'''

|-
| 02:26
| Let us understand '''case statement''' with an example.

|-
| 02:32
| I have already typed the program.So, I will open the file '''case.sh'''

|-
|02:38
|The program prints a warning message when the disk space reaches a certain limit.

|-
| 02:45
| This is the''' shebang line.'''

|-
|02:47
|The location of '''bash '''is different in other '''Linux''' flavours like '''CentOS, RedHat etc.'''

|-
|02:55
|Previously used '''/bin/bash''' points directly to the''' binary file'''.

|-
|03:01
|'''env''' used here, abstracts the true location where '''bash''' is located.

|-
|03:07
|This '''shebang '''line improves the portability of the script on any '''GNU/Linux''' system.

|-
| 03:16
| '''df -(hyphen)h displays disk space''' usage in human readable form.

|-
|03:22
|The output is piped to '''sort -rk5''', which sorts the fifth column in reverse order.

|-
|03:31
|The output is then passed to '''awk 'FNR == 2 {print $5}''''

|-
|03:38
|which extracts the fifth field of the second line.

|-
|03:43
|Eventually, the output is passed to '''cut -(hyphen)d “% -(hyphen)f1” '''to strip out '''% sign.'''

|-
| 03:55
| This is the first line of '''case statement.'''

|-
| 03:59
|Here, we compare the '''space''' between 0 and 69.

|-
|04:04
|If match is found, it prints '''"Everything is OK”'''

|-
| 04:08
| Next, it compares the '''space''' between 70 and 89 or from 91 to 98;

|-
|04:17
|If match is found, it prints '''“Clean out. There's a partition that is $(dollar)space % full.”'''

|-
| 04:27
| Here, it compares the '''space''' with 99.

|-
|04:30
|If match is found, it prints '''“Hurry. There's a partition at $(Dollar) space %!”'''

|-
|04:39
| This is the default case condition because the '''asterisk '''will match all strings.

|-
| 04:45
| And this is the end of '''case statement.'''

|-
| 04:48
| Now go to the''' terminal,''' to make the file executable.

|-
|04:52
|Type''' chmod space plus x space case dot sh '''

|-
|04:57
|Type '''dot slash case dot sh'''

|-
| 05:02
| '''Everything is OK.'''Note that the output will vary depending on your system diskspace.

|-
| 05:10
| In my machine, as match is found between 0 and 69, it prints '''Everything is OK.'''

|-
|05:18
|Check the message printed on your machine.

|-
|05:20
|You will be able to understand which '''case statement''' was executed.

|-
| 05:27
|This brings us to the end of this tutorial. Let us summarize.

|-
|05:31
|In this tutorial we learnt, Importance of''' case statement''', Syntax of '''case statement''', With the disc space example

|-
| 05:41
| As an assignment.

|-
|05:42
|Write a menu driven program for mathematical calculation

|-
|05:47
| It should take user inputs '''a '''and '''b'''

|-
|05:51
| It should ask for mathematical opertator (plus +, minus -, division / and multiplication *). Do the calculation, Print the output
