After executing some simple commands like
dos('copy *.txt new.txt', '-echo')
dos('echo. 2 > EmptyFile.txt', '-echo')
I tried to delete the folder in which these files were created. However, Windows gives me the message
"cannot delete "FolderName": the folder is being used by another person/program".
I have to close Matlab to make it work.
How do I solve this? I guess it's something like closing the "session" of cmd commands...
What you're not showing is the change of working directory to your folder. Windows won't let you delete a folder that a process has as a current working directory.
The solution is simple: change the working directory out of that folder. Say:
cd('..')

I've just created a script file in MATLAB, but can not run it. The name of my script is getEnvFiles.m. When I first tried to run it, I got the following result:
>> getEnvFiles
'getEnvFiles' is not found in the current folder or on the MATLAB path, but exists in:
\\wsl$\ubuntu\home\me
Change the MATLAB current folder or add its folder to the MATLAB path.
So, I added this directory (which is actually the current directory) to the search path, but still got the same result:
>> addpath('\\wsl$\ubuntu\home\me')
>> getEnvFiles
'getEnvFiles' is not found in the current folder or on the MATLAB path, but exists in:
\\wsl$\ubuntu\home\me
Change the MATLAB current folder or add its folder to the MATLAB path.
When I check the path, it looks like this directory is on the path:
>> path
MATLABPATH
\\wsl$\ubuntu\home\me
I can further verify that this directory is my present directory:
>> pwd
ans =
'\\wsl$\ubuntu\home\me'
and that getEnvFiles.m is in this directory:
>> ls
. .emacs.d HarborData
.. .emacs~ RawHarborData
.bash_history .landscape at
.bash_logout .motd_shown getEnvFiles.m
.bashrc .profile test.m
.bashrc~ .sudo_as_admin_successful
.emacs
Is the issue that I'm using wsl (Windows Subsystem for Linux), or do I have some other misunderstanding?
Type rehash and then try running your script again. Even though you have added the new directory to your path, you need to update the path cache so that it knows about the new scripts it can see.
The problem seems to lie in WSL's ability to add new files to the directory. When I create a new script within MATLAB, and try to run it, I get the problem discussed above. However, running already existing files is not a problem. For now, my only solution is to close MATLAB after creating a new script and reopen it. Then, I can run it. Although, oddly, I can't open it in MATLAB's editor.....
This may or may not help, but ...
Sometimes you have to prepend execution with .\ in order to run scripts in PowerShell or from within the command prompt (in Windows, I'm not sure about other operating systems).
I get this error quite often, especially when not in Admin mode.
Does this work?
% Get path of executing script.
filePath = matlab.desktop.editor.getActiveFilename; % Note that this isn't necessarily the same as the output of 'pwd()'.
% Or: filePath = mfilename('fullpath')
% Make sure all nested directories of filePath are on the path, then tell MATLAB where you're working.
addpath( genpath( filePath ) ); % If this fails, try one folder up the tree:
% addpath( genpath( fullfile( filePath, '.' ) );
cd( filePath );
Alternatively, it looks like you might have written and saved the script, and then typed it into the command window to execute. If it's not a special type of script (Function/Class/GUI/etc.) then you can simply click 'Run' in the Editor tab (or the F5 key) and MATLAB should prompt you with a 'Change Folder' option, to which you should acquiesce.
If you're running this script through the WSL terminal, try my suggested code.
I configured my Total Commander so I can open a file *.txt i.e. within emacs.
Therefore I setup my Editor
D:\Tools\emacs\bin\emacsclientw.exe "%1"
When I now open my file everything is ok. But when I edit it and save it emacs tells me the following:
Saving file c:/log.txt...
basic-save-buffer-2: Opening output file: permission denied, c:/log.txt
How do I make it run so it can actually edit files?
By Default you should not be saving anything to root C:\
It is just bad practice and by default a normal user does not have permission to it.
Instead, create a working DIR in your Documents folder and a log directory in that, then you will have something like:
C:\Users\Frank\Documents\Working\logs\log.txt
This should not create any permission errrors.
My team faces the need to encrypt all files in a repository with AES256. For this purpose, we decided we are going to zip all files with such encryption, using the same key for all of them.
The problem we have is that these files sit in a NAS, so from windows boxes they are accessible by \ to them.
The directory structure is something like this:
Original Structure:
Root
-1
|--folder1
|---file1.ext
|---file2.ext
|--folder2
|---filea.ext
|---fileb.ext
|--folder2.a
|---filec.ext
and so on...
Essentially, what we need is to have all the original files contained in a zip file, keeping their original names, which would be something like this:
Desired Outcome:
|-Root
|-1
|--folder1
|---file1.zip
|---file2.zip
|--folder2
|---filea.zip
|---fileb.zip
|--folder2a
|---filec.zip
and so on...
To accomplish this, we tried a batch script that calls 7zip, but it only works if it's run from the root directory, which is something we cannot use as the files are not in a server.
Here is the syntax of the batch script we came up with:
FOR /R %%i IN ("*.wmv") DO "C:\Program Files\7-Zip\7z.exe" a -mx0 -tzip -pPasswordHere "%%~dpni.zip" "%%i"
But, as wrote previously, it only works when run from the root folder, which is something we cannot do as files sit on a network location.
Mapping the drive or making a symbolic link to it doesn't do the trick either.
I've also checked on 7zip to do this, namely, making use of its "-r" operator, but I couldn't find a way to get the desired outcome (namely, recurse through all folders in the remote tree structure -there are a lot of them...- and keep the original file name).
I'm open to any suggestions as any kind of script, trick or guizmo that gets the job done will be more than welcome. =)
Thanks a million in advance!,
Sebas.
----SOLUTION----
I actually found a sollution here, mapping the drive in a different way (it's so simple it just made me feel stupid(er), but it's altogheter beautiful).
Using the batch script below, the remote share can be mapped like so:
You can map a drive using
net use X: \\server\directory
and then you can change to that directory using
pushd X:

I am trying to copy a folder from the network path to my machine .But while copying the folder the robocopy suddenly got stuck in copying 1 file from the folder and did not proceed forward . I am seeing the error ERROR 3 (0x00000003) , "The System cannot find the path specified." , even though the file did exist in the source directory.
The command that I use is
ROBOCOPY source destination /MIR /Z /Log+:logs.txt
I am seeing this issue when my executable is triggered by the task scheduler. This issue does not happen when i run the exe directly. Any idea why this could be happening and also how to fix this problem
When robocopy claims it cannot find a file, it often means it is running into permission issues. If your script works from the command line, but not from the task scheduler, make sure the task uses your user credentials. You can set them in the task properties on the general tab under security options.
example
There is a file "sample.rar".
Folder structure is: "rising\dawn\ and here there are many (folders1, folders2 and file1, file2)" in this archive.
i have used following command
7z.exe x "sample.rar" "rising\dawn\*" -oi:\delete
The result is:
all files and folders in "rising\dawn\" are extracted to "i:\delete" folder but the empty parent folders "rising\dawn\" are also created in destination folder.
e.g. destination looks:
i:\delete\rising\dawn\folder1\file1.bmp
i:\delete\rising\dawn\folder2\subfolder
i:\delete\rising\dawn\file1.txt
i:\delete\rising\dawn\file2.txt
i don't want "rising\dawn\" empty folders to be created but the folder structure there onwards must be as is in the archive.
i want the result:
i:\delete\folder1\file1.bmp
i:\delete\folder2\subfolder
i:\delete\file1.txt
i:\delete\file2.txt
at last i found a way out solution. thanks to the winrar support. i have accepted it as an answer below.

Finally this gave me the result.
Thanks to winrar support.
rar x -ep1 sample.rar rising\dawn\* d:\e\delete\
i have tried other answers given here, this is the only correct answer.
don't forget to upvote.
You can extract the archive normally and
1) move the lower level folder/files to where you would like it, then
2) remove the extra top level archive folders.
Code to do so will depend on the exact task.
Using e command instead of x and add -r option works well.
Like this:
7z.exe e -r "sample.rar" "rising\dawn\*" -oi:\delete
My executable version is "7-Zip [64] 9.20 2010-11-18",
And the platform is Windows 8.1.
This command line eliminates unnecessary parent folders and preserves the hierarchy of folders.
You need to use the e command rather than the x command:
7z.exe e "sample.rar" "scholar\update\*" -oi:\delete
Using e instead of x means 7zip will extract all matching files into the same folder (as specified via the -so switch, or the current directory if this isn't specified) rather than preserving the folder structure from inside the archive.
