| 00:01
|Welcome to this spoken tutorial on '''File Handling''' using '''Scilab'''.

|-
| 00:06
| In this tutorial, we will learn

|-
|00:08
|file handling with the following functions:

|-
|00:11
|'''write()''' function

|-
| 00:12
|'''read()''' function

|-
|00:14
|'''mopen()'''

|-
|00:15
|'''mclose()'''.

|-
| 00:16
|For demonstration, I am using '''Ubuntu Linux 12.04''' operating system with '''Scilab''' version 5.3.3 installed.

|-
| 00:26
| You should have basic knowledge of '''Scilab'''.

|-
|00:29
| If not, for relevant spoken tutorials please visit '''spoken hyphen tutorial dot org'''.

|-
|00:36
|| Now we will see some '''functions''' in '''Scilab''' which are useful for file handling.

|-
| 00:41
|File handling involves-

|-
|00:44
| writing to a file using '''write()''' function,

|-

| 00:47

| reading from a file using '''read()''' function,

|-
| 00:51
| opening an existing file using '''mopen()''' function and

|-
| 00:55
| closing an already opened file using '''mclose()''' function.

|-
|01:00
| Let us start with writing data to a file.

|-
|01:03
|For this purpose the '''write()''' command is used.

|-

|01:07

|Switch to the Scilab console window.

|-

|01:10

|To begin with let us create a matrix of random numbers.

|-

| 01:15
|| Type: ''' random underscore matrix is equal to rand into bracket 20 comma 1 close the bracket semicolon''' and press '''Enter'''.

|-

| 01:29

| Now check the present working directory.

|-

|01:32

|| Type '''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()'''.
