If you downloaded a series there are often folders for each episode. Each episode folder often includes another folder called “Sample” with a short demo video file.
Series -> Season 01 -> Episode 01 -> Sample -> sample.mkv
To get rid of these you can use the “find” and “rm” command. To remove each sample folder with its content you have to use the remove command with an “-r”.
find -name "Sample" -exec rm -r "{}" \;
If you already have an LXC with Debian running, add the following three lines to the lxc config (path /etc/pve/lxc/xxx.conf) and reboot the container:
lxc.apparmor.profile: unconfined
lxc.cgroup.devices.allow: a
lxc.cap.drop:
Now simply install docker.
sudo apt update && apt upgrade -y
sudo apt install apt-transport-https ca-certificates curl gnupg2 software-properties-common
curl -fsSL download.docker.com/linux/debian/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io docker-compose
Running and managing docker containers requires sudo privileges. If you don’t want to type sudo for every commmand, add your current user to the docker group.
sudo usermod -aG docker ${USER}
Docker should now be installed, the daemon started, and the process enabled to start on boot. Check that it’s running.
sudo systemctl status docker
Test if the installtions is working correctly with hello-world.
sudo docker run hello-world
Each container you will create gets a unique ID and name you can look up with “docker ps”. To remove the docker instance just use “docker rm” followed by the ID or the container name.
sudo docker ps -a
sudo docker stop relaxed_williamson
sudo docker rm relaxed_williamson
Generate key, copy key to server and finally ssh passwordless into your server.
ssh-kegen -t rsa
ssh-copy-id root@ip
ssh root@ip
View your generated key with:
cat /home/user/.ssh/id_rsa #local
cat /home/user/.ssh/authorized_keys #server
To disable password authentication permanently you have to edit the ssh config. Be sure to first backup before editing. Now just set PasswordAuthentication to “no” in your config and restart the ssh daemon.
cp /etc/ssh/sshd_config /etc/ssh/sshd_config_bak
nano /etc/ssh/sshd_config
service ssh restart
Since version 5.13.0 the blur effect is integrated into the Plasma desktop. Follow this guide to activate the blur effect for your terminal.
To activate the blur effect for other windows (like the dolphin file manager), use Force Blur.
Or use Kvantum (Qt theme engine) with a theme that supports blur, i. e. Materia Blur.
When receiving an error mounting an NFS share inside your VM:
sudo mount -t nfs xxx.xxx.xxx.xxx:/data/media /mnt/nfs/media
mount.nfs: access denied by server while mounting xxx.xxx.xxx.xxx:/mnt/nfs/media
Just change the network adapter of your VM in VirtualBox from “NAT” to “Bridge Mode”.
As alternative you can force the usage of the TCP protocol when mounting, like it is described here.
Install VirtualBox 6.0 on Linux Mint.
wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -
echo "deb [arch=amd64] https://download.virtualbox.org/virtualbox/debian bionic contrib" | sudo tee /etc/apt/sources.list.d/virtualbox.list
sudo apt-get update
sudo apt-get install -y virtualbox-6.0
Download the Manjaro ISO here.
Run VirtualBox and create a new VM with type “Linux” and version “Arch Linux (64-bit)”. If done, go to Settings -> Display and switch Graphics Controller to “VBoxVGA” to be able to change the screen resolution of your VM. For transparency effects, you can also check “Enable 3D Acceleration”.
(Changing this setting didn’t work on my existing VM, only when creating a new VM. So it’s important to do this step before installing the OS.)
Now go to Storage and add your Manjaro ISO as optical drive.
Start the VM and go through the Manjaro installation process. If done, shutdown your VM, go back to settings and remove the Manjaro ISO as optical drive. Else it will boot again into the installer. Now start the VM again.
To run with the VirtualBox Guest Additions, you only have to install virtual-box-utils inside your VM:
sudo pacman -S virtualbox-guest-utils
sudo add-apt-repository ppa:kubuntu-ppa/backports
sudo apt upgrade
sudo aptitude install --with-recommends kubuntu-desktop
Without the “recommends” you’ll get some errors about missing dependencies like here:
The following packages have unmet dependencies: kubuntu-desktop : Depends: software-properties-kde but it is not going to be installed
Because Linux Mint 19.2 is based on Ubuntu 18.04., the Kubuntu backports only provides Plasma Version 5.12.19.
Ubuntu 18.04 contains Qt Version 5.9.5 and Plasma 5.13 will need at least Qt 5.10.
You can check the current Qt and Plasma version with
kinfocenter
Find their Github here and their Documentation here. They recommend to install via NPM. So first we have to install the Node.js runtime if you have not yet.
If you follow the Node.js installation guide you would use:
sudo apt-get install curl python-software-properties
curl -sL https://deb.nodesource.com/setup_12.x | sudo bash -
But this will lead into the following, since 19.2 Tina is not yet support (on 19.1 Tara it will run fine).
## Confirming "tina" is supported...
+ curl -sLf -o /dev/null 'https://deb.nodesource.com/node_12.x/dists/tina/Release'
## Your distribution, identified as "tina", is not currently supported, please contact NodeSource at https://github.com/nodesource/distributions/issues if you think this is incorrect or would like your distribution to be considered for support
So we have to do it manually. I used this little how-to i found on Github:
# Add missing signature
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-key 1655A0AB68576280
# Replace misconfigured sources file. Change version of node you like to have. 8/10/12
echo -e "deb https://deb.nodesource.com/node_10.x bionic main" | sudo tee /etc/apt/sources.list.d/nodesource.list
echo -e "deb-src https://deb.nodesource.com/node_10.x bionic main" | sudo tee -a /etc/apt/sources.list.d/nodesource.list
# Update packages and install
sudo apt update
sudo apt install nodejs
Finally install Bitwarden-CLI with a single line.
sudo npm install -g @bitwarden/cli
Now you can login into Bitwarden. If you have enabled any two-step login method, you have to add the parameter “–method” and a specific value for the login in method you can find here. In my case “0”, as I’m using TOTP.
bw login --method 0
If you successfully logged in, you will get your session key and are able to read your passwords:
To unlock your vault, set your session key to the `BW_SESSION` environment variable. ex:
$ export BW_SESSION="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
> $env:BW_SESSION="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
You can also pass the session key to any command with the `--session` option. ex:
$ bw list items --session xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Simple plugin to get autosuggestions from your history while typing in your Zsh shell. If you are using Oh My Zsh, the installtion is done in 3 steps. Look here.
Just grab the plugin:
git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
Add it in your ~/.zshrc (zsh config):
plugins=(zsh-autosuggestions)
And restart the terminal. Done.
