| Backing up btrfs partition using cp -pav Posted: 28 Nov 2018 11:07 AM PST I need to back up my root partition temporarily because I forgot to set up LVM. I'm going to delete the partition after backing up, set up LVM, then recopy the files. All copying will be done with cp -pav. Will this destroy my filesystem? [link] [comments]  |

| Thinking of uninstalling Windows, what should I know beforehand? Posted: 28 Nov 2018 11:06 AM PST Hi! I'm new to the PC world in general, so please bear with me. I've grown fed up with windows 10, and am thinking of switching to Linux. The thing is, I have a semi-decent laptop (ASUS ROG Strix GL753VD), and I use it for gaming and work, I have a lot of software that I don't think is supported on Linux. Will I still be able to game, to run autocad and stuff like that? How does it all work? Will I still have graphic card drivers and stuff like that? I'm sorry those are extremely basic questions, but I'd really like some help. Thank you [link] [comments]  |

| Ffmpeg creating different outputs on each run Posted: 28 Nov 2018 01:28 PM PST I'm using FFMpeg to convert audio files on a program I'm using. In the past, the files were converted only when required, however I'm moving some stuff around. I used an MD5 hash to check if there were identical files already around. However, running the same FFMpeg command on the same file twice produces two different outputs. Here's the command I used:
Any help is appreciated, thanks [link] [comments]  |
| lost file trying to move it. any help? Posted: 28 Nov 2018 09:34 AM PST tried moving a document to my dropbox folder through command line instead of doing it the normal GUI way because im trying to get more acquainted with the command line.
i thought this was the right command and its nowhere to be found. i tried

| Posted: 28 Nov 2018 10:27 AM PST I'm running Kubuntu 18.04 but would like to switch back to Ubuntu 18.04. If I install the gnome DE, and remove the Plasma DE (how do I remove one I'm not using?) would I break programs that I have installed? Would a simple fix broken dependencies and such? Would permissions get screwed up with anything? [link] [comments]  |

| Posted: 28 Nov 2018 01:50 PM PST I have my data directory /mnt/md0/data and a backup directory that LuckyBackup backs up to every day /mnt/backup/md0. I just noticed that a few files that I changed/edited over the past several weeks weren't correctly copied over with LuckyBackup. The files in question were a TV series I ripped. I noticed that I had all the file names right but there were a few duplicate episodes. (Different names but same episode.) I corrected this on the /mnt/md0/data folder but since I guess the names were the same, LuckyBackup didn't catch it and the backup location still contained the wrong episodes. All together, this is about 24TB of data. I'm sure that 98% of it is correctly backed up but I need to know for sure. Is there a Linux utility that I can point to two folders and it will compare all the files based off their MD5 hash and show me which ones are different? I know that combing through 24TB of files won't be quick and I'm fine with that. My alternative is to delete everything on my backup array and look for a different program that I can configured to back up files based solely on a files MD5 value. In case it matters, using Linux Mint 19 and this is a home media server. I've been using Linux for almost 2 years but still consider myself a noob so I might need spoon fed. :) Thanks!

| How do I make existing Linux partition dual boot? Posted: 28 Nov 2018 06:51 AM PST I had Windows 10 (W10) and Linux Mint 19 (LM) set as dual boot on my ASUS laptop. It was fairly simple, I installed LM after W10, it just worked. Few days ago I've got Samsung EVO SSD, so I reinstalled W10 on SSD (I'm using my LM only for some specific tasks, I left it on HDD). It kept using old EFI partition for new install, so I had to nuke W10 system recovery partition and EFI partition to be able to safely delete old system partition on HDD. Obviously because of that my LM dualboot isn't working, but its partition is still there. I have sort of understanding that I have to 1) boot from Linux live usb, 2) install grub2 (that's what I used to have, I think) and 3) let grub2 scan partitions and generate settings. I'm not sure if it's supposed to be in chroot, or which disk/partition I have to install grub2 to. Also I've never really touched EFI based boot, except from "press install and it works" point of view, so I'd rather not break things. Any advice on how to proceed? EDIT STEP 1: After running grub-mkconfig everything was exactly the same as before. So I googled a bit, did [link] [comments]  |
| May have ruined my Kubuntu installation trying to change my username. Posted: 28 Nov 2018 12:44 PM PST Hey all. For various personal reasons, I wanted to change my username using the instructions found here. I used the accepted answer, but I ran into some problems with the part where you have to fix the files that are hardcoded with your old username on the system. Apparently KDE hardcodes a shit ton of filepaths in its config files, and so parts of my system actually broke. For example, I lost ALL of my saved WiFi network information, meaning I have to get the passwords for those again. Additionally, my laptop's brightness and volume buttons will occasionally fail to work upon login (Why not always?). I tried some instructions here to try and find all references of my old username using grep and sed, and I let this run overnight. Unfortunately, I don't think it did anything at all, since I still see my old username in most configuration files. I think it also stressed my laptop too much since the brightness couldn't be turned down while it was running, and now my Is a clean install of Kubuntu the only way to get back to normal? (aside from the fan problem) I didn't [link] [comments]  |
| Posted: 28 Nov 2018 12:19 PM PST I saw this over at r/linuxquestions in the comments section and thought this is very helpful knowledge for those just starting with Linux and wanting to learn more when it comes to terminal. Not sure if this is specific to bash or what. ; will run the second command even if the first one fails && will run the second command only if the first one succeeds || will run the second command only if the first one fails [link] [comments]  |
| Posted: 28 Nov 2018 11:33 AM PST So I'm trying to make my Tilix terminal a little bigger. I'm using the CTR+ALT+UP etc but it is not resizing it. Any idea how? Thank you! [link] [comments]  |
| Posted: 28 Nov 2018 11:14 AM PST With multiple computers, VMs, and re-installs with hardware changes, we might want to merge various custom kernels. I'm wondering how you all manage your kernel configs and merge them for evolving computer setups. Which diff tools do you prefer? Which commands do you frequently use? (I'm mainly asking for Gentoo, but I use other distros as well, so all suggestions welcome) [link] [comments]  |
| Optimising palettes (24 bit > 8 bit) Posted: 28 Nov 2018 04:34 AM PST I sometimes need to convert true color images into 256 colour images. The GIMP is OK, but sometimes gives poor results. In the past I've used products that give far better results (e.g. the old Alchemy for DOS, or WinImages) but is there something similar for Linux? Something that has excellent default colour reduction and also allows tweaking? [link] [comments]  |
| Brother Printer no longer working after reformat Posted: 28 Nov 2018 03:49 AM PST So my distro (KDE Neon) crashed hard for some reason. It was probably recoverable but much faster in my case to just reformat. So I did and installed the printer drivers that I always do from Brother's website. The weird thing is that I can use the built-in scanner (so its not a usb issue or anything like that) using Skanlite. But I can't print. Every job seems to go through just ifne but the printer is not printing. It can print test pages (so its not busted). But I can't print test pages through my Distro. I've tried resetting the printer on its end to see if I somehow didn't hit a funky setting. Can someone please help Edit: Solved I guess. I saw in the terminal an error, and on whim I told it to install the two things
Don't know why it didn't do it automatically. But its working for now [link] [comments]  |
| Making a persistent, repeating, systemd service Posted: 28 Nov 2018 06:54 AM PST The answers I find to searching 'systemd service loop/recurring' don't work or don't address the right problem - I need to make eternally repeating scripts. Simple example:
The final goal is one script to keep a reverse ssh connection alive so I can provide IT support to machines I'm not near, and make unison run and wait 5 minutes after it's complete (crontab with 5 minutes set can make this run multiple times). Current example: [Unit] Description=Alfred After=display-manager.service [Service] ExecStart=/home/alfred/.local/bin/random-task.sh Restart=always Type=simple User=ghost Group=ghost IgnoreSIGPIPE=no[Install] Alias=alfred.serviceIf I run:
.... the first time it complained it's starting too often. Now it says it has two running processes but I'm not seeing any output. [link] [comments]  |
| How can I change password storage (Thunar) Posted: 28 Nov 2018 02:59 AM PST When you mount an encrypted device Thunar is asking something like: - don't store password - store password for this session - store password forever Now, how can I remove an already given permission to store such a password?

| BASH read command failing on long line? Posted: 28 Nov 2018 12:19 AM PST I started constructing the script below according to a guide to scrape a downloaded HTML file, and I'm noticing that it finishes with no error message upon reaching a 522,000 character long line, and it fails to echo said line. I thought it might have been my ARG_MAX but getconf ARG_MAX returns 2097152 so that doesn't seem to be the case. Any ideas? ``` !/bin/bashdeclare -a ARRAY filename="asdf.html" exec 10<&0 exec < $filename let count=0 while read LINE; do echo $LINE ARRAY[$count]=$LINE ((count++)) done exec 0<10 10<&- echo ${ARRAY[@]}``` [link] [comments]  |
| Dell laptop suddenly lost connection over wifi Posted: 28 Nov 2018 03:33 AM PST Hello all, hope you can help. I have a Dell Vostro series laptop running on ubunt 16.04 that doesn't seem to be able to connect to the internet over my home wifi network (though it's displaying as connected). It works over ethernet on the same network and wifi is fine in my office, hotspot,etc too.
