Where is the magick command of Imagemagick?

This may be a simple question, however, I couldn't find a solution.

The ImageMagick contains a program named magick to convert image formats from one to another.

When I wrote $ magick into the console, I've got the following error.

Command 'magick' not found, did you mean:

  command 'magic' from deb magic (8.2.157+ds.1-1)

Try: sudo apt install <deb name>

So, how to install the magick to Ubuntu 20.04.02 TLS?

Do I need to download and compile from the source or the name of the command in Ubuntu is just different from magick and it is already installed with the default ImagaMagic package?

I can confirm, no magick command on my Ubuntu 20.04 either.

However, try convert:

$ convert --help

So I would try reproducing the examples in the documentation that you linked, but substituting magick with convert.

Update:

Thanks to @steeldriver, I have quickly learnt a lot about ImageMagick :)

The ImageMagick version 6 command line API (shipped with Ubuntu 20.04 and earlier) consists of these commands:

animate, compare, composite, conjure, convert, display, identify, import, mogrify, montage, stream

ImageMagick version 7 will unify these commands under the magick command.

Be aware that from version 7 on, such combos also become possible:
