Time	Narration
00:01	Scilab વાપરીને File Handling પરના આ સ્પોકન ટ્યુટોરિયલમાં તમારું સ્વાગત છે.
00:06	આ ટ્યુટોરીયલમાં આપણે શીખીશું.
00:08	આપેલ ફન્કશન સાથે ફાઈલ હેન્ડલિંગ:
00:11	write() ફન્કશન
00:12	read() ફન્કશન
00:14	mopen()
00:15	mclose().
00:16	પ્રદશન માટે હું ઉપયોગ કરી રહી છું સંસ્થાપિત Scilab 5.3.3 વર્જનના સાથે Ubuntu Linux 12.04 ઓપરેટીંગ સીસ્ટમ
00:26	તમને Scilab નું સામાન્ય જ્ઞાન હોવું જોઈએ.
00:29	જો નથી તો સંબંધિત ટ્યુટોરિયલ્સ માટે અમારી વેબસાઇટ જુઓ. spoken hyphen tutorial dot org.
00:36	હવે આપણે સાઈલેબમાં અમુક functions જોશું જે ફાઈલ હેન્ડલિંગ માટે ઉપયોગી છે.
00:41	ફાઈલ હેન્ડલિંગ સમાવે છે-
00:44	write() ફન્કશન ને વાપરીને ફાઈલ લખતા ,
00:47	read() ફન્કશન ને વાપરીને ફાઈલમાં થી વાંચતા.
00:51	mopen() ફન્કશન ને વાપરીને વર્તમાન ફાઈલ ખોલતા.
00:55	mclose() ફન્કશન ને વાપરીને ખુલેલી ફાઈલને બંદ કરતા.
01:00	ચાલો હવે ફાઈલ માટે ડેટા લખવાથી શરૂઆત કરીએ.
01:03	આ માટે write() કમાંડનો ઉપયોગ થાય છે.
01:07	સાઈલેબ કન્સોલ વિન્ડો પર જાઓ.
01:10	આના સાથે શરૂઆત કરવા માટે રેન્ડમ નંબરનું એક મેટ્રીક્સ બનાવીએ.
01:15	ટાઈપ કરો: random underscore matrix is equal to rand into bracket 20 comma 1 close the bracket semicolon અને એન્ટર દબાવો.
01:29	હવે વર્તમાન કાર્ય કરતી ડિરેક્ટરીને તપાસીએ.
01:32	ટાઈપ કરો pwd .
01:34	In my case, the present working directory is slash home slash fossee .
01:39	Make sure that you are in a directory where you have read & write permission, before you execute these commands.
01:47	Now we will write the content of variable random underscore matrix into a text file using the write command.
01:55	Type:--> write into bracket into quotes random dash numbers dot txt close the quotes comma random underscore matrix close the bracket and press Enter.
02:18	Let us see whether this file has been created.
02:21	I will minimize the Scilab console window.
02:23	And open the file which will be created and saved in the fossee directory of my computer.
02:33	You can see the data from variable random underscore matrix is written in a text file random dash numbers dot txt.
02:42	I will close this file.
02:45	Coming back to the Scilab console.
02:47	Now we will see how to read the data from a file.
02:50	For this we will use the command read as follows:
02:55	Type: new underscore vector is equal to read into bracket into quote random dash numbers dot txt close the quotes comma 20 comma 1 close the bracket and press Enter.
03:18	The read command reads all the data from the file mentioned in the argument,
03:23	in this case random dash numbers dot txt,
03:27	and stores in the variable new underscore vector.
03:31	Press Enter to continue the display.
03:35	If we modify the above command as:
03:39	new underscore vector is equal to read into bracket into quotes random dash numbers dot txt comma 19 comma 1
03:49	The read command reads only 19 data values from the file mentioned in this argument,
03:56	in this case random dash numbers dot txt,
03:59	and stores in the variable new underscore vector.
04:03	Issue this command on the Scilab console and verify the output.
04:08	Now let us see about the mopen() function:
04:12	fd = mopen into bracket file-name comma mode
04:17	mopen command is used to open an existing file in a way compatible to C fopen procedure.
04:25	mode is a character string that controls whether the file is opened for:
04:30	r = opens the file for reading.
04:34	rb = opens a binary file for reading.
04:39	rt = opens a text file for reading.
04:43	w = creates a new file for writing or opens and truncates a file to zero length.
04:50	wb = creates a new binary file for writing or opens and truncates a file to zero length.
04:58	wt = creates a text binary file for writing or opens and truncates a file to zero length.
05:06	a or ab = appends (opens a file for writing at the end of the file or creates a file for writing).
05:14	r+ or r+b = opens a file for update (reading and writing).
05:20	For eg. fd underscore r is equal to mopen('random-numbers,'rt')
05:30	The above command opens the 'random-numbers' as a 'text and read-only' mode.
05:37	mclose into bracket fd:
05:40	closes the opened file by using mopen
05:43	where fd is the file descriptor of the opened file.
05:48	If fd is omitted, mclose() closes the last opened file.
05:53	That's all we have in this tutorial.
05:55	We have learnt -
05:56	File handling with the following functions:
05:59	write() function
06:00	read() function
06:02	mopen()
06:03	mclose().

06:08	It summarizes the Spoken Tutorial project.
06:11	If you do not have good bandwidth, you can download and watch it.
06:14	The spoken tutorial Team:
06:17	Conducts workshops using spoken tutorials
06:20	Gives certificates to those who pass an online test.
06:23	For more details, please write to conatct@spoken-tutorial.org.
06:30	Spoken Tutorial Project is a part of the Talk to a Teacher project.
06:34	It is supported by the National Mission on Eduction through ICT, MHRD, Government of India.
06:41	More information on this mission is available at http://spoken-tutorial.org/NMEICT-Intro.
06:50	This is Anuradha Amrutkar from IIT Bombay, signing off.
06:54	Thank you for joining.
