| How can I change the permission of an external hard drive and access it? Posted: 21 Oct 2021 11:43 AM PDT I try to access an external hard drive with an ntfs filesystem from NixOS. Is it correct that I have to create a mounting point? Where do you usually create a mounting point? and everything looks good: But when I mount the external hdd, the permission changes. This doesn't happen on another computer running Ubuntu. What can I do?  |
| Why is the ammount of Avaible space on a drive less than Size - Used? Posted: 21 Oct 2021 11:43 AM PDT ext4 filesystem As you can see, the partition is 938 GB in size (1 TB SSD), 72 MB is used, but only 891 GB is available for use. What is causing the nearly 47 GB overhead?  |
| Why can't a user delete a directory owned by nobody? Posted: 21 Oct 2021 11:29 AM PDT I configured a basic samba shire to share media files over SMB on my local network without credentials (i.e., as a SMB guest)
When I create a directory called When I try to delete the directory from the system using a standard user account, I get an error message.
Yet, I can delete the folder from using SMB on Windows. What is happening here, and how can I allow any local unix user to delete or modify files created by a guest over SMB?  |
| Why do some popular programs have so bad error flow control? [closed] Posted: 21 Oct 2021 11:04 AM PDT In this case is thunar that's struggling trying to display a folder with many images, last time it was firefox trying to open infinite tabs on reply to a nasty script. Why don't developpers handle this so basic errors? It's as simple as a warning message do you really wan't to continue? Why do they have to charge against my full system? Surely I should configure some niceness and QoS but why doesn't this comes by default? No graphic application should demand resources that are needed for basic functionality of desktop manager itself. Everyday I'm more critic about our current technological setup, if you think about it, it's flawled everywhere.  |
| How to loop through all files in the current and sub directories to find a string? Posted: 21 Oct 2021 11:04 AM PDT Hi I am trying to loop through a directory and all its subdirectories to find the string 'foo' in all the files, for example.

| Xfce4: How to decide which application to open the url based on patterns Posted: 21 Oct 2021 09:18 AM PDT The system has a bunch of browsers (like Chromium and Brave).

| Posted: 21 Oct 2021 08:46 AM PDT Ok. So I'm not a linux user generally, but I haven't had a good experience with Windows so I decided to switch over and install Pop_OS. It was really good for a time, but I eventually realized I couldn't install a lot of the software I need to use for my work (Unity/Unreal/DaVinci Resolve for example). I want to uninstall the OS and switch to Windows 11 but I can't because every time I try to get to the boot menu, dialogue pops up and says "encryption key?". Then when I enter it, it just goes straight back into Pop!_OS. Is there any way to wipe the ssd or to get the computer to run from a thumb drive (actually access the boot menu)?  |
| How do I recursively cut an audio file automatically? Posted: 21 Oct 2021 08:26 AM PDT Okay so to begin. I'm developing a game however the sound engine that it uses is not advanced and dose not allow sounds to be paused, sounds can only played and stopped. I can not change this sound engine. It is quite the annoyance because I have a pause menu. Every time the pause menu is activated the games music has to pause also. When the pause menu is deactivated that games music has to start from where it left off. However due to the sound engine not being that advanced I can not achieve this. To get around this issue I want to take an the audio file of the games music (2 minuet length) and trim it every 0.05 seconds from beginning to end, making a new file that is shorter then the previous every time it is trimmed. This would result in my having over 2400 audio files that get gradually shorter. How do I do this automatically?  |
| Where to put kickstarter config for RHEL flash install Posted: 21 Oct 2021 08:25 AM PDT I can't figure out where to put a Redhat Enterprise linux (currently using 7.9 but will do 8 next) Kickstarter file on a flash drive install. Flash drive is the full RHEL DVD installed directly to the flash drive with DD. I moved the ks.cfg to the root of the flash drive and modified I've tried file, hd, iso, from one article I found out how to install Every time I boot the flash drive and select the isolinux entry that I added that append to, it boots the GUI installer. The kickstart file was generated by the RedHat kickstart generator and validated with My kickstart file is not complicated. DHCP network, add a user, post install run a script.  |

| Organizing files by dates contained within them Posted: 21 Oct 2021 08:44 AM PDT I am currently trying to write a script that organizes a list of files into subdirectories by their dates. The dates are contained on the first line of every file in the format I then want to create subdirectories This is the code I have so far. This is a sample file I'm struggling to find a way to create the subdirectories and store each file in the correct directory. Any code suggestions would be much appreciated. I am using the bash shell.  |
| Terminate a pipeline if no data flows for n seconds Posted: 21 Oct 2021 08:46 AM PDT I have a piece of software that produces data on stdout for a while, then continues running but doesn't output any more data. I have a pipeline that takes that output and processes it further, saving the output in a file. However, because the original process keeps running after it finishes producing output, I have to terminate this manually. Is there a command that will kill the running program once it hasn't produced any output for some number of seconds? I know about the timeout command, but that looks like it operates on a fixed timeout. I don't have a reliable way of determining how long the software will keep outputting for. Example: Suppose I have I currently run something like I would like to terminate the pipeline once  |

| sudo service sshd restart failed on AWS EC2 instance Posted: 21 Oct 2021 08:31 AM PDT I have created AWS EC2 instance and deployed Asp.Net Core Web API application.

| How do I check cgroup v2 is installed on my machine? Posted: 21 Oct 2021 09:33 AM PDT I want to try cgroup v2 but am not sure if it is installed on my linux machine Since cgroup v2 is available in 4.12.0-rc5, I assume it should be available in the kernel version I am using. https://www.infradead.org/~mchehab/kernel_docs/unsorted/cgroup-v2.html However, it does not seem like my system has cgroup v2 as the memory interface files mentioned in its documentation are not available on my system. https://www.kernel.org/doc/Documentation/cgroup-v2.txt It seems like I still have cgroup v1. Follow-up questions Thanks Brian for the help. Please let me know if I should be creating a new question but I think it might be helpful to other if I just ask my questions here. 1) I am unable to add cgroup controllers, following the command in the doc However, I got "echo: write error: Invalid argument". Am I missing a prerequisite to this step? 2) I ran a docker container but the docker daemon log complained about not able to find "/sys/fs/cgroup/cpuset/docker/cpuset.cpus". It seems like docker is still expecting cgroupv1. What is the best way to enable cgroupv2 support on my docker daemon?  |

| WBC_ERR_DOMAIN_NOT_FOUND only for a specific account Posted: 21 Oct 2021 10:05 AM PDT Platform: RHEL 5.10 Version: Samba 3.6.6-0.136 Only on a single VM, one of my co-workers is able to log into the VM using his AD credentials without issue, whereas my account appears to have trouble locating user information: Thinking that winbind could have just cached a negative return (for instance AD wasn't available when it had to refresh its cache entry for my user account) I set both I didn't find anything in Which seems like it contains the actual problem but I don't know how to read the error and would like some guidance on this. It seems like it doesn't like the SID associated with my AD account for some reason, but I don't know why or how to work around it. I'm present in the active directory domain referenced, but for some reason it's unable to pull only my account's information.  |

| Accidentally set screen resolution too high, it won't change back Posted: 21 Oct 2021 08:13 AM PDT I'm using VMware with Arch and XFCE. The default screen resolution was too small for me so I wanted to change it to something higher. I accidentally selected a screen size that was too big and I thought it was going to go back to the screen size it was before but it just stayed as a black screen. I have rebooted VMware and Arch is still a black screen. Is there anyway to fix this without reinstalling?  |
