Regex search in PDF reader
I am using zathura, as I enjoy its minimalist approach, but I would also switch to mupdf or anything else if this would solve my problem.

I am using zathura, as I enjoy its minimalist approach, but I would also switch to mupdf or anything else if this would solve my problem.
I need to highlight every word (in PDF and epub documents) one by one from start to finish because I can concentrate better on the text if I have some kind of motion in it. My approach would have been to perform a regex search that matches every word, but neither zathura nor mupdf support regex in searches. Is there a way to do this?
I would try to fork zathura but to be honest I don't really want to spend that amount of time if there is another minimal Gnu/Linux compatible document viewer that does what I need. And if there is any way to use terminal tools like
pdfgrep for highlighting the results in zathura that would also do the job.

Are there any utilities to verify integrity of common document types used in the office environment (docx, pptx, xlsx, pdf, common image, audio and video files) without using the actual applications?
Contents of some documents of ours proved to be damaged due to storage issues. So, I need to sweep across the whole filesystem to verify all the files and report which of them are actually impacted.
The damaged content can be anywhere in the file, so just verifying file headers - like the *file* command does - or checking the file properties (length, dates), etc., won't be good enough. I need a tool which would open the files, verify integrity of their internal structures, and report the result either on stdout or through an exit code.
A solution which would do all the job and provide a final report would do as well, of course, if it already exists - it would save me a lot of scripting work. ;-)
I assume random technical issues, not a deliberate tampering - so I do not need to verify the actual contents of the documents. What I need is to identify the files which would probably fail to open in their respective apps.
Looking forward to receiving your suggestions.

Zathura's best-fit command ('a') for documents with varying page size
I'm usually using the wonderful document viewer 'zathura' for reading PDF-files. Typically, for some documents, the first page of the document is slightly larger than the rest (for example, a photograph of a book cover). In this case the 'best-fit' function (key 'a') of zathura always adjusts the zo...
I'm usually using the wonderful document viewer 'zathura' for reading PDF-files. Typically, for some documents, the first page of the document is slightly larger than the rest (for example, a photograph of a book cover). In this case the 'best-fit' function (key 'a') of zathura always adjusts the zoom relative to the first page of the document, implying that for the rest of the document the pages are displayed smaller than they should be. This is particularly annoying when reading documents in 'double-page mode', leading to results as terrible as the following:
**My Question:** Is there any way to change this behaviour such that the 'best-fit' function adjusts the size relative to the currently viewed page?

How do I convert a '.pages' file to something unix-y?
I have a file with the extension '.pages´. I _think_ that means iWork, but I'm not sure. Anyway, searching for "convert pages linux" produces a fair few false negatives! Does anyone happen to know a way to convert it to something reasonable on Linux?

2. I'd like to number some pages with Roman numbers and some with Arabic numbers, for example: i, ii, iii, ..., x, 1, 2, 3, ... (usage case: some introductory pages are numbered Roman in the book)
Is it possible to do it on Linux?

Simple Scan crashes almost immediately upon start-up
I'm using `simple-scan` on Debian and it is now always crashing. It worked fine a few months ago. I suspect that something got upgraded (I'm running `bullseye`) and broke things.

I'm using
simple-scan on Debian and it is now always crashing. It worked fine a few months ago. I suspect that something got upgraded (I'm running bullseye) and broke things.
The output from simple-scan says:
simple-scan: thread-watch.c:165: avahi_threaded_poll_quit: Assertion `pthread_equal(pthread_self(), p->thread_id)' failed.
Abortldd /usr/bin/simple-scan to make sure all the packages associated with all the libraries are recent, including libc6. I also tried running with simple-scan -d, but the debug output proved useless. I also tried strace /usr/sbin/simple-scan to look at all the shared libraries that were being loaded and they all had recent versions.
I noticed that the libavahi shared libraries are loaded dynamically (i.e., not visible via ldd) by simple-scan. So, I made sure that those were also recent.
I also tried xsane, but it has the same problem.
Perhaps unrelatedly, I see the following messages in my system log file:
avahi-daemon: Too many clients, client request failed.scanimage does not crash, but it fails in an unrelated way.
I am at my wit's end and don't know what else can be done.

## Update
Preferably, something with a "drag and drop" mechanics but not necessarily.
AFAIK, WYSIWIG lacks drag and drop mechanics (such as those of Gutenberg/Elementor).

Task focused command-line cheat sheet for linux

There are a lot of "Linux command-line cheat sheets" on the internet. But often they only list the commands, sometimes sort and describe them.
What I am looking for is something I would call a "task based" cheat sheet, where I can "ctrl+f" for *what* I want to do and find the corresponding command. Since beforehand I don't know *how* (i.e. the command) to perform the task.
Could someone provide a link or search terms?
#### Explanation:
When trying to do something on the command-line, I normally use google to find a solution. Depending on the complexity of the task, this takes some (unreasonably high) effort and often combining multiple solutions. Also internet access is mandatory for this to work.
I afterwards write this down in a text file and attach some search terms.
Expecting to find similar files on the internet, I search for:
linux task OR action OR work based cheat sheet, linux howto collection common tasks. Those don't return what I look for.

I'm pretty sure that wasn't because of anything I have done: there are no cd commands in ~/.bashrc (and that should not be necessary) and the launcher did not contain anything in the field 'Working Directory' (I put $HOME there just to try, but that does not work either).

I have always found OCR technology to be behind on open source systems. I've also watched the Ocropus project since its infancy. I've tried what I've heard is the best OCR engine available for Linux, Tesseract , and have found it woefully lacking for business documents. Are there any other more promising OCR implementations? What about the even more hopeful goal for interpreting handwriting? What is possible on *nix systems in this field?

I need to rename a few thousand text files to be the first word in the text file plus the file extension (.txt) using the terminal. All the files are in a single directory, and are currently named int the pattern "xx0001.txt' through 'xx9999.txt'.
The first word in each file is of this pattern: '##221251', so maybe my issue comes from needing to comment out the pound signs.
I've tried:
rename File.ReadAllText('*.txt').split(' ')
Which throws the error:
zsh: no matches found: File.ReadAllText(*.txt).split( )
Thanks in advance for your help. I'm a true novice.

I'm running Arch Linux and using Okular for opening PDF files and FBReader for other ebook formats (Epub, Mobi, etc.). Simply put, here's my question: Assuming some of those documents come from unreliable sources and contain malicious code what can I do to mitigate the risk of compromising the system and opening it for invasion (which can be a common occurrence in this country if you even smell like someone who holds opinions the government disapprove of)?
A few more specific questions:
Is just opening the referred files enough to put my setup at serious risk? The user I use for this is on the sudoers list, so, if compromised, it could be used for escalation.
Suppose I only open the files using a more limited user account, would that at least help?
Outside of setting up a virtual machine only for reading (which wouldn't be practical for a few reasons) or using another computer just for that (same thing), is there anything I can do?

I'm looking for a personal document management system that would:
* track changes in documents in a configured directory tree
* save new files to a content repository (thus allowing of their versioning)
* offer some kind of web gui for browsing the repository - ideally it would allow tracking changes in documents etc
The files I'd like it to support are:
* microsoft word files (doc, docx, xls)
* open office files
* pdf files
* txt files
I've looked through a couple of such systems (DMS-grade) but haven't noticed them having the autonomous scanning option. What I'd like to have is a unobtrusive solution that wouldn't require users to upload documents through web gui. All the versioning, backing up stuff should be transparent to them. Only if they were actually interested in downloading the older version they would fire up the web gui.
Any comments and suggestions are welcomed.

Don't wants: Cloud Based, MySQL.
Most of what I am finding in my searches are business solutions (read expensive), cloud storage and systems that require a MySQL or other database server (service?).

During the search it tells me where the pattern is in relation to the length of the document (25-30% or more) but once I take out the pattern, there is no way to tell how big the document is.
Is there a way, maybe some configuration variable or something that I need for vim to parse and share with me the location in percentage form whenever I'm in the document.

I'm starting with Emacs, and testing around I wondered if I could edit my own .docx file from there, just to explore its features and that stuff.
But my surprise is huge when, having the text perfectly displayed in my screen, I can't manage to write over it. Emacs' DocView tells me that it's a read-only document, and that I have to type C-c C-c in order to edit it. That displays me the display (sorry), but I can't see where can I edit it.
Does somebody know anything about this issue? It's the first day I'm trying Emacs, but it seems quite shocking to me it can't deal with docx files.
