I'm trying to copy several files with changing filenames. It seems very easy but I can't seem to work out how to do it without actually listing out the filenames in their entirety. The first few letters of the filenames correspond to the subject names which I'm looping through one by one. In each folder, there are 2 files, one is something like this subj1_load1_vs_load2.img, one is subj1_load1_vs_load2.hdr. I want both of them copied. Below is what I have:
subj={'subj1','subj2','subj3','subj4','subj5'}
for i=1:length(subj)
source=fullfile(filedir,subj{i},sprintf('^%s_.*\.*',subj{i})); % this doesn't seem to work
destination=fullfile(destdir,subj{i});
copyfile(source,destination);
end
I've also tried:
source=dir([filedir subj{i} strcat(subj{i},'*')]);
This appears to needlessly complicate since I will need to deal with .name. But perhaps I don't know how to use this well.
Anyway, the problem is with source as I'm trying to find the files i want to copy.
I'd appreciate any suggestions.
Below is Daniel's answer (which solved the issue for me)
source=fullfile(filedir,subj{i},strcat(subj{i},'*'))

I have a bunch of Archives that I want to extract. Problem is, there's a lot of them, and it's a lot of info to move around. I'd like to do it all at once. It's probably taken more time to research than to do it manually, but research is more interesting.
TL;DR: Would like help with 7-zip command line to extract multiple archives into their own directory. Autohotkey, Powershell, and batch files answers would also be nice if you are feeling extra helpful.
Win10, latest update and all that. I've been using 7-zip, so if there's a better extractor for this it might be a helpful suggestion. I have a little experience with coding, so I can usually pars an example and apply it to my project, but I can't come up with code on my own. So with that said, I'm comfortable using cmd, autohotkey, powershell, batch files, and a few others, but I need an example before I can do anything. haha
So, in my research, I found
(7z x -o"...\Stellaris\mod\Examples\" "...\content\281990\*")
for cmd, which works, except that extracts everything to the same dir since the archive files are in the root archive dir (I think that's why; if they were one folder down, it should work like I want right?). I don't think you can use environment variables in the path(?). Not sure what would make it work here...
Powershell: I only recently started tinkering with it so the one script I found didn't make any sense to me. And never found anyone using AutoHotKey for this.
And finally a **batch file* I found here seemed to come closest (normally I'd comment on that thread cause apparently it's still active, but I don't have 50 rep), but I wasn't sure how to modify it for my purposes:
#echo off
SET "filename=%~1" #Where does the working dir path go?
SET dirName=%filename:~0,-4% #How/where would you put in wildcards?
7z x -o"%dirName%" "%filename%"
I don't mind using any method, though I might prefer AHK? I'm probably most experienced there.
If you made it this far, wow, I'm impressed! I hope it was coherent enough to understand (probably not at first?). And maybe a little entertaining? I think I'm funny. Let me know if I should add or remove anything for the future. I know it's probably way too much context, but I would rather have too much than not enough, and I'm never sure what would be relevant and what would not. I'm not happy with my code format here, but I didn't quite understand what the help was saying about whitespace and I'm not familiar enough with Markdown yet (I wanted comments to be in line). Also, I'm honestly not sure about the tags.
EDIT: Added TL;DR at the top, and...
Found an answer via a program that does this. I'll post it in an answer as well: ExtractNow seems to be a bit outdated, last update was in '17, but it did what I wanted it to.
For interactive use at the command prompt:
for %z in ("\path\to\dir\subdir\*.zip") do #echo 7z "-o\path\to\extracted\%~nz" "%~z"
This won't run 7z, but it will print out the commands. Once you are satisfied that the printed commands look fine, remove the #echo to execute them.
In a batch script you must of course duplicate the % signs.

Assuming you were using Windows, 7-zip would have worked fine to do what you wanted. The only thing you were missing is the * character, which 7-zip expands to be the archive name when used with the -o switch:
7z x "dir\subdir\*.*" -o"dir\*"
So 7z x -o"...\Stellaris\mod\Examples" "...\content\281990\*"
becomes:
7z x -o"...\Stellaris\mod\Examples\*" "...\content\281990\*"
Also be aware that *.* does not mean any file under 7-zip. 7-Zip takes *.* to be name of any file that has an extension. To process all files just use a "dir\subdir\*" without the extra .*.
Unfortunatly for me we have a legacy file system which has been around since the dinosaurs roamed. Over time, files have been moved/copied to a location which has generated a folder + file structure which is too long to simply copy from one location to another. (long file name)
What I see as a solution is to use powershell to map a drive to each file location, copy it then recurse for each.
e.g.
net use w: \newlocation\
net use x: \silly long file path\folder1\
xcopy x:\file.txt w:\folder1
then use for each to copy the same structure as it was originally.
I know it seems long winded but I cannot think of a better way forward. I've tried Robocopy which is supposed to avoid this problem but through much testing.. Nope. Still fails to copy.
Can you please suggest a good method for doing this?
Not sure if you are still looking for an answer but you can try the program called Beyond Compare which should work for you.
Honestly, I didn't spend too much time with it as it has bunch of options but I know people who successfully use it every day for files with long file names.
I need to replace a file on a zip using iOS. I tried many libraries with no results. The only one that kind of did the trick was zipzap (https://github.com/pixelglow/zipzap) but this one is no good for me, because what really do is re-zip the file again with the change and besides of this process be to slow for me, also do something that loads the whole file on memory and make my application crash.
PS: If this is not possible or way to complicated, I can settle for rename or delete an specific file.
You need to find a framework where you can modify how data is read and written. You would then use some form of mmap to essentially read and write small chunks. Searching on NSData and mmap resulted in this Post, however you can use mmap from the posix level too. Ps it will be slower than using pure memory no way around that.
Got it WORKING!! JXZip (https://github.com/JanX2/JXZip) has made exactly what I need, they link to libzip (http://www.nih.at/libzip/) that is a fully equiped library for working with ZIP files and JXZip have all the necessary Objective-C wrapper code. Thanks for all the replys.
For archive purposes, as the author of zipzap:
Actually zipzap does exactly what you want. If you replace an entry within a zip file, zipzap will do the minimum necessary to update it: it will skip writing all entries before the replaced entry, then write out the entry, then write out all entries after the replaced entry without recompressing. At the moment, it does require sufficient memory for the entries after the replaced entry though.
I would like to delete multiple files that contain a substring. Say for example I would like to delete all the files that has the substring my. Assume that my directory contains 4 files: photo.jpg, myPhoto.jpg, beachMyPhoto.jpg, anyPhoto.jpg, since the term of search is my the files that I am interested to delete are myPhoto.jpg and beachMyPhoto.jpg (case insensitive).
My proposed solution (which I know how to do) is to use NSFileManager class, and use the function contentsOfDirectoryAtPath:error: to read all the directory contents, and then search by a loop for a hit. If a hit is found I delete that file.
What I don't like in my proposed solution is that it is not that efficient especially if the directory contains too many files and the hit is a small number. Is there a more efficient way to do this?
If you don't want a big array loaded into memory, you can try -[NSFileManager enumeratorAtURL:includingPropertiesForKeys:options:errorHandler:]. Since you only want the immediate contents of the directory, you would invoke -[NSDirectoryEnumerator skipDescendants] for each directory that it returns.
If your concern is iterating over all of the items in the directory, testing for your match pattern, well that's unavoidable. Any technique you would hope to use has to somehow iterate over all of the items in the directory and test for a match. The only question is whether that iteration is exposed to you or not. In Cocoa, it is. You could drop down to the glob() function if you want an alternative where it isn't.
I have several files in a GridFS Document Store and what I'd like to do is to pipe this data into a zip file via stdin in NodeJS. So that I will end up with a zip file containing all these files.
Now my question is how can I give the files a valid filename inside of the zip file. I think I need to emulate/fake a file header containing the filename?
Any help is appreciated!
Thanks
I had problems when writing zip files with Node.js not long ago. I ended up doing something similar to what is described in Zip archives in node.js
I can't help you directly with your problem, but at least I hope I can point out some things:
Don't try to use node-archive. Even if the description says it allows to create zip files, the moment I read the source code (since documentation is unexistant) I realized that's just a lie. It only exposes methods for reading.
Using zip by spawning a process, like recommended on the provided link, seems to be the best way. Something that would work is copying the files to a local folder with whatever name you desire and then calling the zip command, just to delete the files afterwards.
The other option, which seems ok, is to use zipper (https://github.com/rubenv/zipper, although better just use npm). The reason I'm not really wishing to use it is because there's not that much flexibility, it seems to have been done in a day and it hasn't been modified since the first commit, so I'm not sure it will receive maintenance (sure, you could just fork it...).
I swear the day I have an entire free weekend with no work I will write a freaking module that does this as complete as possible. It's silly that there isn't and it shouldn't be that much struggle. blablablarant.
Edit:
Not sure if it was there before, but now I've been using the node-compress module (also using gzippo). It works fine.
