What are you thinking of that is example-less?
All in all, I find that manpages on Linux are usually pretty good, particularly compared to systems like MacOS where many daemons and utilities seem to have no manpage at all. People are far too quick to slag manpages, which probably has something to do with the `man` utility itself being a bit archaic. Common Linux desktops could probably do a better job of advertising GUI-based manpage readers like khelpcenter.
But also I can't imagine what good more examples will do anyway. `-lahR` cover the vast majority of common uses.
At least we're past the bad old days when you'd open a man page and it would just be a stub saying "look at the info docs, IDIOT"
This is what microsoft did well with powershell's help system. They have examples. Tons of them.
Why man pages do not is beyond me when most of the time, an example or two is all we need. I bet most people go to the man pages and then google for examples because the man pages weren't helpful.
