“Pywal is a tool that generates a color palette from the dominant colors in an image. It then applies the colors system-wide and on-the-fly in all of your favorite programs.”
I’m using Variety to change my wallpaper every day automatically. To always get the right colors in my terminal I added some lines in my .zshrc that will always grab the current wallpaper and pass it to PyWal. I’m sure a bash pro would do this in just one line… 🙂

In meinem NAS nutze ich seit vielen Jahren als Motherboard ein ASRock C2550D4I mit einer recht stromsparsamen on-Board CPU und einer BMC/IPMI Schnittstelle, welche Fernwartung über einen separaten LAN Port möglich macht.
Bei einem BMC Update hat sich leider die WebGui verabschiedet und ich musste mir die Sache auf der Konsole anschauen. Dafür habe ich IPMITOOL installiert und verwendet. Dabei stellte sich heraus, dass lediglich die Netzwerkeinstellungen verloren gegangen sind.
Hier einige hilfreiche Befehle im Umgang mit dem IPMITOOL, welche mir geholfen haben. Über diesen Weg lässt sich ebenfalls das Passwort des Admin Users zurücksetzen.
# install
sudo apt install ipmitool
# display sensor & network settings
sudo ipmitool sensor
sudo ipmitool lan print 1
#set network settings
sudo ipmitool lan set 1 ipsrc static
sudo ipmitool lan set 1 ipaddr 192.168.178.3
sudo ipmitool lan set 1 defgw ipaddr 192.168.178.1
# Reset password

If a pdf file is located in a different folder, you have to add the path like this: $home/Downloads/source1.pdf If you want to merge all pdf’s of the current folder you cant type:
Suspend a application. Resume it again by fg (resume in foreground) and bg (resume in background). Use jobs if you have multiple suspended applications and use fg %# (where # is the job number) to get it back on screen or end it with kill %#.
Ctrl-D
is same as typing exit
Pos1
like Ctrl-A
End
like Ctrl-E
Ctrl-R
Search terminal history
Some of the shortcuts are also recognized by other applications, like Ctrl-U on Ubuntu’s graphical login screen.
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”.
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
