Hi Gottfried, Like almost all Linux distributions, Guix uses the ‘ls’ and many other fundamental commands from the GNU coreutils package. These are the ones you'll see called ‘Linux commands’ in many silly tutorials, like ‘cp’, ‘mv’, etc.
Almost all GNU commands support the ‘--help’ option, which will print a list of all documented options as part of the usage instructions. Those that don't (often CLI commands not written for the GNU project) support the traditional single-letter ‘-h’ switch which does the same thing. So try ‘ls --help’, or ‘ls -h’! It should be exhaustive. And it's often easier to skim than the proper manual is… However, it won't tell you which options Dired likes and which it does not. I don't know if that's documented but if it is, that's Dired's job. Kind regards, T G-R Sent on the go. Excuse or enjoy my brevity.
