I tried to run the shell command on Ubuntu 22.04.4 and got this:

$ shell
Command 'shell' not found, did you mean:
  command 'shelr' from deb shelr (0.16.3-2.1)
  command 'spell' from deb spell (1.0-24.2)
  command 'bshell' from deb avahi-ui-utils (0.8-5ubuntu5.1)
  command 'rshell' from deb pyboard-rshell (0.0.31-0ubuntu1)
  command 'jshell' from deb openjdk-11-jdk-headless (11.0.20.1+1-0ubuntu1~22.04)
  command 'jshell' from deb openjdk-17-jdk-headless (17.0.8.1+1~us1-0ubuntu1~22.04)
  command 'jshell' from deb openjdk-18-jdk-headless (18.0.2+9-2~22.04)
  command 'jshell' from deb openjdk-19-jdk-headless (19.0.2+7-0ubuntu3~22.04)
Try: sudo apt install <deb name>

I'm going to close this until there's a good reason to suggest this change.
