Here's why the suggestion (in Randall's “form letter”) to use `<file command` was bad in 1995, and is still bad today. In bash, if you type `<file co` and press TAB, you don't get command completion on `co`. You get filename completion. If you type `cat file | co` and press TAB, you get command completion. (Bash has behaved this way for as long as I can remember, and I just verified it in bash 5.0.3 on a Pi.)
