[Firefox] ShadowFox + Add-Ons

 , , ,

Since the Dark Theme in Firefox 68.0.2 still has a flashing white page when opening a new tab, it’s no useable dark theme in my opinion.
That’s why I prefer ShadowFox (Github) instead of the native dark theme. Easy to install and many ways to do further customizing.

Firefox Add-ons I use:

Also I like bookmarks in the toolbar centralized. Just append the following lines to the userChrome.css.
The file is placed in your Firefox Profile: ~/.mozilla/firefox/profile_name/chrome/userChrome.css

#PersonalToolbar {
  display: flex !important;
  justify-content: center !important;
}

Terminal

[Terminal] Neofetch + lolcat

 , ,

1. Install neofetch.

sudo apt install neofetch

2. Install lolcat.

# When installing with "apt install lolcat", you will get version: lolcat 42.0.99
# To get the current version use:
sudo apt remove lolcat -y
wget https://github.com/busyloop/lolcat/archive/master.zip
unzip master.zip
rm master.zip
cd lolcat-master/bin
sudo gem install lolcat

3. Append the following line at the end of your ~/.bashrc (or at the beginning, if you are using zsh: ~/.zshrc) file, to get the neofetch output on every terminal run.

neofetch | lolcat

If you want to change the config of neofetch, you’ll find it here:

~/.config/neofetch/config.conf

[Shell] Replace pattern

 , , , ,

How to replace a specific pattern in a file or folder name. In my case I needed to correct the season on each file of a series from “S08” to “S09”:

for f in *; do mv "$f" "$(echo "$f" | sed s/S08/S09/)"; done

If you want to replace a pattern recursive, use the command “find”:

find . -name '*' -exec bash -c 'echo mv $0 ${0/S08/S09}' {} \;    // with echo for testrun

Terminal

[Terminal] Command Line Audio Visualizer

 , , , ,

Look at Github cli-visualizer for installation instructions.

Path to config file: ~/.config/vis/config
I’ve decommented these two lines:

audio.sources=pulse
colors.scheme=rainbow

Run with “vis”.
Use the following controls when running:

KeyDescription
spaceSwitch visualizers
q or CTRL-CQuit
rReload config
cNext color scheme
sToggle Mono/Stereo Mode
+Increase scaling by 10%
–Decrease scaling by 10%
Terminal

[Terminal] Simple man page

 , , ,

If you are using the man command, e.g.:

man find

You will often get a very long manual.
But there is a much easier to read man page called tldr, with examples how to use the command.

apt install tldr
tldr find

Terminal

[Terminal] Terminal cat grep

 , , ,

Most users are using cat and grep for searching for a string in a file:

cat filename | grep search_string

But you can use grep completely without cat:

grep search_string filename

Terminal

[Terminal] !!

 ,

You can repeat the last used command by typing “!!”. For example if you typed:

apt upgrade

as non root user, you will get the following message:

error: you cannot perform this operation unless you are root.

But you don’t have to type the whole command again with sudo in front of it, just type:

sudo !!

And it’s doing a:

sudo apt upgrade

[Mint] Citrix Receiver on multiple monitors

 , ,

Citrix Receiver download.
Here is the offical how to guide.

The following command can be used to test for window manager support.
If there is no output, there is no support.

xprop -root | grep _NET_WM_FULLSCREEN_MONITORS

Further troubleshooting infos here.

In my case, I just had to launch the configuration manager and set it to “Full Screen”.
