Write a sentence in multiple files

Hi,

I have a many '.txt' files in a folder.

a.txt, b.txt, c.txt ......

Now I want to open each one of them one by one and print the following sentence in the 5th line from the beginning of each one them including the file name.

The sentence is :

a.txt > "I am in a file"

b.txt > "I am in b file"

these line should be printed on the 5th line from the file starting.

Can you please tell me the procedure

And this snippet:

% Open the file for reading in text mode.
fileID = fopen(fullFileName, 'rt');
% Read the first line of the file.
textLine = fgetl(fileID);
lineCounter = 1;
while ischar(textLine)
	% Print out what line we're operating on.
	fprintf('%s\n', textLine);
	% Read the next line.
	textLine = fgetl(fileID);
	lineCounter = lineCounter + 1;
end
% All done reading all lines, so close the file.
fclose(fileID);

Good luck.

Thank you. By the way, it's not a homwwork question.

I am trying to understand a code and see which functions are getting called.

For example:

getcl.py ->

def getcoord():

....................

....................

return

similarly I have 256 files in a folder. I don't know which sequence they are getting called.

So, I want to read each file as text - so that I can print at the 5 the line from the starting because generally

the function definitions will be starting at 4 th line.

print("I am in getcl")

So, If this statement gets printed in the 5th line, this will get printed on my console when program is running.

Now the program looks like:

getcl.py ->

def getcoord():

.print("I am in getcl")

...................

....................

return

I don't need the function name, just file name is sufficient.

I hope you understand

To find out what functions a file requires, you can do

[requiredFileList, toolboxList] = matlab.codetools.requiredFilesAndProducts(fullFileName);

Attached is my function wrapper for it.
