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
Version: ImageMagick 6.9.10-23 Q16 x86_64 20190101 https://imagemagick.org
Copyright: © 1999-2019 ImageMagick Studio LLC
License: https://imagemagick.org/script/license.php
Features: Cipher DPC Modules OpenMP 
Delegates (built-in): bzlib djvu fftw fontconfig freetype jbig jng jpeg lcms lqr ltdl lzma openexr pangocairo png tiff webp wmf x xml zlib
Usage: convert-im6.q16 [options ...] file [ [options ...] file ...] [options ...] file

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


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:

magick convert rose.jpg -resize 50% rose.png
  • I see. Do you have any idea for the name change? It is better to create an alias instead of substituting.

  • No, I don't know why they are different in the documentation and in Ubuntu. But I would not be so fast with creating an alias. Such unexpected things often happen for a reason. We might not know the reason, but being quick to alter our systems (and dismissing the wisdom of the managers of our Ubuntu release) might set us up for unexpected surprises later on...

    The name change goes the other way I think - magick is the newer API, available from ImageMagick 7 (whereas Ubuntu 20.04 uses ImageMagick 6). See for example Porting Guide: Shell API or Command-line Interface Commented Feb 11, 2021 at 15:59
  • Not all functionality, e.g. filename globbing, is supported in version 6's convert. Commented Jul 26, 2022 at 18:32
  • Same issue on Ubuntu 22.04. ImageMagick is on 6.9.11-60.
