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
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:
| Key | Description |
|---|---|
| space | Switch visualizers |
| q or CTRL-C | Quit |
| r | Reload config |
| c | Next color scheme |
| s | Toggle Mono/Stereo Mode |
| + | Increase scaling by 10% |
| – | Decrease scaling by 10% |
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
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
Just hit “CTRL” + “R” and you get into the search mode:
(reverse-i-search)`':
and exit with “CTRL” + “G”
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

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

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