Earlier quoted context omitted.
My favorite example: `cp -r` is recursive. `scp -r` is recursive. `chmod -r` removes read permissions; `chmod -R` is recursive.
I ever use chmod without specifying at least one of ugoa. Helps with that mistake.
Example in "Early 1970s" is notoriously bad. Text says: "it would be given some number of filenames as command line arguments, and it would read those ... Options didn’t exist". Example shows: unneeded usage of `cat` as if `wc` is non-standard utility and cannot process file names by itself, option for `wc` is used. It contradicts text in both ways!
Is there any actual, useful, worthwhile reason for avoiding useless `cat` though?
