I have a situation where we have several thousand image files that have become corrupted on our server (Windows 2008 R2 x64). I have a working image file that I want to replace the corrupt files with. The files must retain the same name and path (size, timestamps, etc do not matter).
So the basic idea would be to replace each corrupt image file with the working file.
I do not write code, only the occasional windows batch file.
Should I use VB or PowerShell (or something else) for this? What will the script look like for this?
I apologize in advance if this question is too basic for stackoverflow.
You don't really need a batch file,
try looking at the for command
e.g.
FOR /R %f in (*.jpg) DO copy newfile.jpg "%f"
This should do a recursive search and copy newfile.jpg over the jpg's it finds.
It all boils down to how you are identifying the broken jpgs.
When I dont use a wild card for example
FOR /R %f in (broken.jpg) DO copy newfile.jpg "%f"
Then newfile.jpg gets copied to every subdirectory. If I use a wildcard ( *,?) the command works as expected. Is there a way to have this commend work with a (set) that does not contain wildcards?

I'm looking for a way to automate archiving where after I plug my two external drives I can copy all my resources. The problem is that I have different file structures on my laptop and on both external drives so I need to select specific folders to be copied. It means that I can't select one root folder and copy it straightforward. I tried to find a way to declare more than one path in the cp command and in the copy command, without success. An example path:
/my_programming_stuff
/folder1
/folder2
/folder3
/folder4
I want to select only the first 3 folders to copy them into external drive1 and external drive 2. The idea is to create a .bat file that will copy everything at once ( in the best case scenario it will be copied simultaneously on both external drives, so it will be much faster). Another problem is that there needs to be a bypass the ntfs long path limitations (max. 260 characters).
Flags that I want to use:
Copy the files and directories and all of their attributes,
including ownerships and permissions.
Recursively copy directories and their contents.
When copying files from one directory to another, only
copy files that either doesn't exist or are newer than the
existing corresponding files, in the destination
directory.
data verification (so it's certain that the copy was verified)
progression bar with time eta
Until now I was using Total Commander to do this but every day I need to pick only a few folders to be copied which takes time and is inefficient.
I have experience with Bash and PowerShell but I am not sure how to handle this topic.
Create a static batch file with robocopy commands. I think /copyall is the only switch you need to specify for all this. Other defaults should satisfy requirements.

I think your time will be better spent learning how to use either FastCopy or FreeFileSynce. I used FreeFileSync some years ago but got disgusted with the it's constantly changing format of its xml file used for starting a backup, so I switched to FastCopy. But it looks like FreeFileSync may be getting their act together and I aim to do some experiments over the summer to see if I want to switch back to it.
Both can handle the long filename format issues, both can be executed by a batch file, both seem to have a lot of quality, but FreeFileSync has more features - and more bloated because of the features. But speed wise, I think FastCopy is probably one of the better products out there and very streamline in use and design.
I'm trying to use diff3 in this way
diff3 options... mine older yours
My problem is that I probably can't use it, since all my 3 files contain a "dash" within.
The manual mentions:
At most one of these three file names may be `-', which tells diff3 to read the standard input for that file.
so I probably have to rename filenames before running diff3.
If you know for a better solution or a workaround, please let me know about. Thank you!
At most one of these three file names may be `-', which tells diff3 to read the standard input for that file.
It does not state, that your filenames should not contain dash symbols. It simply says, that if you want to, you can put - instead of one of the names, in which case the standard input will be read instead of reading one of the files.
So, you can have as many dashes in your filenames as you like and diff3 should work just fine.
However, on Windows putting filenames in "" for escaping space characters does not work, and I failed to find a suitable workaround. However, you can automatize the process of renaming files (if the files are relatively small, this would not even be too inefficient):
#echo off
copy %1 tempfile_1.txt
copy %2 tempfile_2.txt
copy %3 tempfile_3.txt
"C:\Program Files (x86)\KDiff3\bin\diff3.exe" -E tempfile_1.txt tempfile_2.txt tempfile_3.txt
del tempfile_1.txt tempfile_2.txt tempfile_3.txt
Put this in a file like diff3.cmd, then run diff3.cmd "first file.txt" "second file.txt" "third file.txt".
P.S. Moving files would be more efficient (if they are on the same disk volume as the script, which they are not in your case), you could even move them back to where they were initially, but for some time they would not be present at their original folder.
My question is how to use MATLAB to search for a certain type of files in a folder. I give an example to detail on my question:
Suppose we have the following folder as well as files in it:
My_folder
Sub_folder1
Sub_sub_folder1
a.txt
1.txt
2.txt
Sub_folder2
3.txt
abc.txt
In this example, I want to find all the .txt files in My_folder as well as its sub-folders. I was wondering what I could do with MATLAB. Thanks!
To my knowledge Matlab doesn't have an inbuilt function to do recursive directory searches, however there are a couple available for download on Matlab Central: here and here.
Alternatively you could write your own recursive function and use the dir function to search at each level for files matching your criterea or other directories to recurse into.
I agree with the Matlab Central options -- another method which I've used when MLC is not an option (no network, or customer computer, etc) is the quick and dirty dos commands:
dos(['dir /s/b ' mywildcard])
The /s will do a recursive directory search for whatever wildcards you specify, and /b will make it so you only get filenames (complete will full path, but no headers, file sizes, etc).
This is obviously platform dependant, so is mostly used when you are forced to work without your "standard" set of utilities you've accumulated.
Even though an answer has been accepted, I would like to point out Matlab's dir function.
This built-in function returns the contents of the folder in question. Furthermore, it indicates which content is a folder of its own. Therefore, with a little loop one could use this function to search sub-directories as well.
I don't understand the behaviour of the COPY command when using a wildcard.
I have a single text file in C:\Source called mpt*.asm and I want to copy it to C:\Dest. This is needed from a batch script, and I can't be sure of the exact name of mpt*.asm (it may be mpt001.asm for example). The destination name should be exactly mpt.asm.
If I use:
COPY C:\Source\mpt*.asm C:\Dest\mpt.asm
The file file is copied, but has a extra (0x1A) character appended to the end of the file.
If I use:
COPY C:\Source\mpt*.asm C:\Dest\mpt.asm /B
I don't get this spurious character.
If I don't use a wildcard, I don't get the spurious character either. It seems unlikely there is a bug in COPY, but this behavior seems unexpected.
Is there a way of doing this copy without resorting to using /B?
I have never seen that before, but it does append an extra arrow character for me too.
You can work around the issue using xcopy instead.
echo f| xcopy C:\Source\mpt*.asm C:\Dest\mpt.asm
If you read copy /? it says
To append files, specify a single file for destination, but multiple files
for source (using wildcards or file1+file2+file3 format).
So by using a single filename as the the dest, and using a wildcard in the source, it may interpret that as appending, which may be what the extra character is for, but as you aren't appending anything you can see it.
I'm only guessing but that may explain it.
I have a number of files in a folder, by mistaken in some of files I enter the wrong name
for example :
filename like : abcefxyz.txt while I suppose to enter abcdevwxyz.txt
that is I simply want to replace ef string in filename with devw
how can I do this using command prompt?
please help...
EDITED
I have a thousands of files whose name like : SomethingLongString_OutdoorGames_DateTime.txt
(which I suppose to enter) but
Accidently in some of files, may be hundreds or thousands in number, I have enter SomethingLongString_IndoorGame_DateTime.txt
I simply want to replace IndoorGame string in filename with OutdoorGamestring (precisely saying).
Here SomethingLongString and DateTime strings in filename is different for different file.
I think this example is more helpful to understand my problem...
on windows use
I dont know how to replace some chars with others,but u can rename this way
dirpath> ren abcefxyz.txt abcdevwxyz.txt
DUNNO.. if they are all TXT files then isolate them in a folder.
From there use Advanced Renamer to a file with NO extension
this way you can use 26 letters to rename the bunch.
CMD use would be Ren A* A (1,2,3,4 etc)
or XCOPY a* A using an older computer..
in a batch you could use for # (filename) do (ren) statements
Would this help?
