[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] 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

[Linux 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”.
