I run Mylar on my Xubuntu server to manage my comic collection. I found out recently that there’s a tool that can convert the embedded .jpgs to .webp to save space, but it only works on cbz files and not cbr (zipped vs rar for those who don’t know). I wanted to convert all of my cbr to cbz so that I could run the tool on all my comics, so I needed to search hundreds of subdirectories for them and move them to the same folder to be processed.

Under Windows, I’d just type *.cbr into the search bar built into Explorer from the root comic directory, hit enter to get a list of files, select them all, and move them to the new folder. On Xubuntu, it’s nothing like as simple.

I found the search option in Thunar which opened Catfish, typed in *.cbr, and got a no files found message. After looking through the very limited options, I started searching for a way to do it. About thirty minutes later I’d found dozens of links telling me to use different, Terminal only, tools, but nothing about how to search subdirectories from the Catfish GUI. Purely by accident, I found a post from 2012 that mentioned the fact that Catfish doesn’t use wildcards, so just search with .cbr, something that’s not mentioned in the official docs.

I tried it, and it searched the subdirectories too, and found my files! Except there was no way to copy or cut and paste, just open, show in file manager, copy location, save as, or delete. No good options for almost 500 files across several dozen locations.

I ended up asking Chat GPT how to do it, and doing it through the Terminal, using this:

‘find . -type f -name “*.cbr” -exec mv {} /path/to/destination ;’

This is pretty basic functionality, and I had to resort to getting help to use the Terminal :(

    I didn’t say at any point that I want Linux to behave like Windows, I just used Windows as an example of how easy it should be to use a GUI file manager to carry out very basic file operations. Why do people on this community sem to assume that just because I don’t like the way that something works that I don’t know how to do anything? It’s quite condescending.

    Secondly that way is stupid even in windows, you’re destroying all of the organisation you had with no possible way of recovering it. How do you plan on putting the comics back into the folders they were on before you moved them all to a single folder?

    No, I didn’t. My first sentence says that I run Mylar to manage the comics. I moved the files into Mylar’s watch folder so that it would pick them up and process them again. Since I added the cbr comics, I’ve turned on an option in Mylar that automatically converts new comics to cbz. While doing this, it renames them according to the name of the comic series, and adds metadata to the cbz file that is not in the cbr. While I probably could have found another way to do this, I already have Mylar up and running. Why would I make more work for myself when I have an existing tool that does it automatically and to my pre set preferences?

    As far as running random code goes, I’d already found several examples of find being used to find files, and mv is a pretty straightforward command. While I could have put the string together myself with a little bit more searching, I tried Chat GPT to see if there was a GUI based way to do it. Not because I don’t like to use the terminal, but because I thought I must be missing something. Basic file operations are pretty much the whole point of file managers, so finding out that Thunar and Catfish couldn’t perform a basic task was a bit of a shock. It’s not a complex task for a GUI, and other OSes, and apparently other file managers according to some of the replies, can do this very easily.

    The script you found is the one I will be using, but I haven’t done anything with it yet. I was doing what should have been basic maintenance on the files I wanted to convert. I did make a simple mistake, in that I read somewhere else that the script couldn’t handle cbr files, and didn’t double check before I started getting everything ready.

    It was the Catfish documentation that doesn’t mention wildcards, and I didn’t think that was odd because wildcards are used pretty much everywhere, plus, the documentation didn’t cover very much.

    The reason Thunar doesn’t bother is that 99.999% of the time when a user searches x what he means is really the regexp .x., so that’s what it does

    That’s part of the problem. They know that wildcards are so commonplace that they assume that it’s what someone means. In itself it’s not a major problem, but a message saying something like ‘You searched for *.cbr, did you mean to search for .cbr?’ might have been more helpful than just a blank results screen.

      Probably because many of us have seen really snide “This is why nobody uses your stupid shitty OS!!” posts/comments so much that “Here’s why people don’t use Linux” for 2435808th time this month just sounds like another condescending prick come to tell us how stupid we are for using “bad” software that doesn’t work like they expect it to. I see that you seem more reasonable than that but I’ve also seen others around here with really crappy attitudes and ideas who’ve maybe stirred up a bit of a defensive mood that your phrasing stepped on.

      …Now I’ve got to go before I also go off on a rant. Here is a virtual pancakes: 🫴🥞

      First of all I owe you an apology, you don’t seem to be the type of person that usually writes posts like “This is why people don’t use Linux: it doesn’t do everything exactly the same as Windows”, and my response might have been overly harsh from past experiences.

      I understand it wasn’t your intention to say that, but that’s quite literally what people understand when you say “I tried to do X the Windows way and it didn’t worked”. And this is kind of what people are trying to get you to see, it’s not that the file manager has or doesn’t have that feature (which BTW I would also expect it to work, and I checked on my computer and it does in fact work so I’m not sure why you couldn’t select things from the search result and drag it someplace else), the thing is that you went about this with the thought “this is how I would do it in Windows”, and refused to accept that people who use Linux would look at this in a different light, i.e. think about how to modify things in place instead on how to move everything to a single folder. In other words what you WANTED to do was convert all images inside cbz and CBR files to webp, so instead of asking yourself how do I run this on all of these subfolders you asked how do I move all of these files into a single folder, and that’s the Windows mentality creeping out, you shouldn’t need to move things around.

      Yes, Mylar will rearrange the things, but here’s the thing, if you had gone with the Linux mentality you would have learned how to run things in folders in place, which would have allowed you to convert the cbr to cbz in place, and then convert the images on those cbzs also in place, without needing to rely on the script supporting either CBR or recursion in the folders nor on Mylar to rearrange things. Also, just thinking about this, how would you have done it? Move CBR to black hole folder, then get them imported as cbz, then move all cbz to a different folder, then run the script, then move everything from that folder into the black hole folder and hope that Mylar doesn’t decide “I already have that comic, delete the one in the black hole since it’s lesser quality than what I already have stored”. Instead of just running the script in the terminal passing the root comic folder, do you REALLY think that your way is simpler?.

      I understand the wildcards not working being confusing, and if you hadn’t mentioned that the documentation doesn’t mention it I would be in 100% agreement with you that it is confusing. My point is that the docs don’t need to mention features they don’t support, my counter example was regular expressions which are a lot more powerful than wildcards yet almost no search bar uses, and their documentation doesn’t mention it.

      The message you suggested is a nice idea, if the search returns empty that would be a nice message that would direct people to the fact that it doesn’t support wildcards, I would encourage you to suggest it on the git repo or proper channel to the developers, or if you’re inclined to write code write it yourself and open a PR, this seems like a nice message that’s very informative and would improve the quality of the software.
