I'm on Fedora 41 (Gnome 47). I installed Foxit Reader to read PDFs, didn't like it, and uninstalled it. Now, the Detailed Type description in the Files program for all PDF documents is FoxitReader Document. How do I remove this reference to Foxit Reader?

I have an Aweseome-wm + xfce system. Where does xfce4-mime-settings stores its values? In particular as regards default apps. The GUI values are different for me from those on ~/.config/mimeapps.list and they have precedence over the latter. Some defaults programs are stored in: ~/.config/xfce4/helpers.rc /etc/xdg/xfce4/helpers.rc But that does not include PDF types.

I have two identical systems running both debian bullseye with gnome3 (3.38.5) and I wanted to add bettebird as my default application for mails. I've created a desktop file in ~/.local/share/applications on system 1 and everything works fine on system 1 - I can select betterbird as the default mail program... I've copied this file to system 2 and betterbird does show up in the activities overview, however, in the 'default application' settings it's not visible. I'm really puzzled & running out of ideas how I can fix this. What I checked/tried after googling for a long time but no success: - Icon & Exec are correct (I can start Betterbird from activities menu) - I have other custom desktop files in ~/.local/share/applications/ and they do work - I changed rights from 644 to 755 (though other desktop files in ~/.local/share/applications do have 644 and do work...) -> no luck of course - I copied thunderbird.desktop from /usr/share/applications to my local folder & adapted entries/renamed file accordingly -> no luck - I tried to open a file with betterbird from my file explorer (nautilus) but Betterbird is also not available from the application list Any ideas how to proceed?

I recently switched from Ubuntu LTS to Debian 12 bookworm. I'm having issues with default application settings so would like to create a 'fresh' ~/.local/share (or perhaps even better ~/.local) folder that matches the apps in bookworm, but if I look in /etc/skel/, there's no .local/ folder. I can someone help me understand how the .local folder is generated and/or updated?

In a previous [question](https://unix.stackexchange.com/q/507943/44919) I enquired about manually setting default applications for different mime types. Other than use tools one among [several tools](https://wiki.archlinux.org/index.php/default_applications#Resource_openers) , it boiled down to add an entry to ~/.config/mimeapps.list, which overrides system wide settings cached in /usr/share/applications/mimeinfo.cache. YMMV depending on your system [XDG Base Directory](https://specifications.freedesktop.org/basedir-spec/basedir-spec-0.7.html) settings and compliance. Our distros usually sport a large mimeapps.list (more than 50 lines in my case). While there are (GUI) tools to add/modify single entries, I didn't find any standard procedure and/or tool to automatically generate the whole mimeapps.list database. If I delete mimeapps.list and install new applications, it is not rebuilt. So, _what process generates mimeapps.list?_

I did a screenshot and also saved it, but I'm unable to figure out where it is. Looking into [the official docs](https://docs.xfce.org/apps/xfce4-screenshooter/usage) didn't tell me more and I also didn't find something quickly searching both the SE network and the whole internet. So this Q/A might provide an answer to the next person to be in the same situation. To reproduce run xfce4-screenshooter, select anything and click on Open with a program. I chose *Gnome Paint Drawing Editor*, but this program also didn't (easily) tell me the location of the file. I failed save as but need the file.

When I open ubuntu(wsl) on windows , usually, it opens as karim_123 user and not as root user. But this time it opened as a root user. How can I return back to my unix linux account(karim_123)? I used **su - karim_123** command but when I close the terminal and reopen it, it opens as root user again so I have to switch back to my user(karim_123) every time I open ubuntu terminal. Additionally, I’m not capable of using **code .** command anymore to open my files in VS code. So it is very annoying and I can’t work on my projects!

Since Awesome Window Manager is mainly a window manager, and not quite a full desktop environment, I don't know how to manage the concept of **default applications**. Without a desktop environment installed, where do I go to configure which web-browser gets launched upon clicking a hyperlink within an application that simply expects my environment to provide a default web browser for servicing URL clicks?

How do I set a manually downloaded Firefox as my default web browser so that clicking a link in another application will open the link in this Firefox? I tried these commands, but they didn't seem to work: update-alternatives --install /usr/bin/x-www-browser x-www-browser /home/user/firefox/firefox 100 update-alternatives --set x-www-browser /home/user/firefox/firefox What do I have to do?

I want to debug a program's behaviour when the user has no default web browser set, but I'm not sure how I'd return to this state after setting one. I know that I can **set** my default browser via xdg-settings set default-web-browser , but what if I want to unset it, i.e., make it so that I don't have a default browser? So far I've tried running $ xdg-settings set default-web-browser '' Which resulted in xdg-settings: no parameter value given I also tried $ xdg-settings set default-web-browser ' ' Which resulted in xdg-settings: invalid application name I'm using a minimal installation of Alpine Linux running i3 in X.Org.

On my Lubuntu (18.10), xdg-open launches VLC Player when the file is not associated to any applications. $ xdg-mime query filetype jquery.js application/javascript $ xdg-mime query default application/javascript # no output $ xdg-open jquery.js Error: no "view" mailcap rules found for type "application/javascript" Opening "/tmp/jquery.js" with VLC media player (application/javascript) On some files, it launches Calibre's E-book viewer (.rb for example). ---- **EDIT** I digged into xdg-open and found it executes following commands: 1. Check filetype with xdg-mime query filename "$file" and xdg-mime query default $filetype 1. run-mailcap --action=view "$file" 1. mimeopen -L -n "$file" The problem lies in mimeopen. Then how can I change mimeopen to open any **unknown files** with featherpad, or specific app? In other words, I'd like to set default fallback application if mimeopen can not find any suitable apps.

I have a server where MAXWEEKS is set to 13 in etc/default/passwd. I know that this setting means that password will expire after 13 weeks. My question is if the user does NOT change the password, does the account become locked out after this or does the system will force the user to change the password when the user logon? What setting can be set to automatically revoke access after certain weeks on inactivity?

How do I set/change the default ftp root folder for a specific user? I want to be able to create a developer account that homes to different sites on a development box depending on what is currently being worked on. EDIT: The server is running Ubuntu and vsftpd.

I have a doubt regarding ACL I want to give permissions to a group using ACL A directory created in SKEL directory needs to have a default ACL set that allows the members of the group “linux” to read all files and subdirectories. But after doing above steps, if i add new user to a system with group as linux it is not applying default ACL.Need some help
