Emacs and/or vi, depending on your inclination, have text editors covered already, of course ;-)
so linux is already there
In terms of usability, moving to FreeBSD from Linux is quite a positive experience. Pity that hardware and software support is limited on the BSDs.
Results from ls would be a few sentences explaining the types of files in the directory. Add a -l on there and it will give you a general overview of the permissions and size of the files. Ex. “These are rather large files that are primarily, but not exclusively, limited to root.”
Results from cat would give a summary of the file. You’d get the same results, with some degree of randomness from more and less as well.
Using any command with sudo would provide the same type of results, but in all caps.
Trying to pipe commands together would be a slop multiplier.
