Thread Subject:

read edit save a text in a loop

Hi,

I could not find any straightforward Commands to ''Read, Edit (find, replace, remove) & Save'' a text file(e.g. in a loop in the m.files ).
i just see some discussions about this in mathwork.
Does any one know if there is any Especial Way / Command for this purpose?

Best regards,
Maryam

Why would you use Matlab for this?
Surely Wordpad or Notepad or similar would be more appropriate?
Matlab stands for Matrix Laboratory, in other words numerical algebra.
What you're looking for is a text editor.
It's like using a nutcracker to open an oyster, sure you can do that, by would you?

You Are Absolutely right.
But when I have to this for 100 files , then it goes on my Nerves doing the same thing for hour which could be done by a loop in matlab.
I want to delet headers , footers , and replace all Commas with dot, for 100 of data files once in week for data analyzig

I found this Function:

http://www.mathworks.com/matlabcentral/fileexchange/18909-replace-strings-in-text-file/content/replaceinfile.m

but I did not try it yet , I am not sure if it works.

...

Either write a script or function to do it in Matlab or find and use
another editing tool that has batch edit capabilities--there is an
almost innumerable veritable plethora of them around...

Never heared of bash?

---------------------------
#!/bin/bash

FILES="$@"
for f in $FILES
do
    vi ${f}
done
--------------------------

If you do not have linux, install VBox (free) and
install Linux (free)

--Nasser

well ,
it works:
fnames={'h000v055.txt' ,......}; % name of the files
nf=size(fnames,2);
for i=nf
 [s, msg] = replaceinfile(',', '.', char(fnames(i)),'-nobak');
end
