Recall stores an image every few seconds. 5 minutes is indeed much worse. Think of all the content they’re missing!

To answer the original question, even though @[email protected]’s advice really is superior:

All commands that can be executed via your shell must live in your $PATH or their subdirectories. You could enumerate all files in there, filter by being executable, and run them with the --help argument.

You can then filter these commands by their exit code. If --help is a recognized flag, the exit code should be 0. Otherwise it should be something else. (Running every command blindly might be a bad idea though.)

My initial guess was that sudo would eat up the echo’d foo as the password. Maybe sudo works differently when invoked via zsh?

Can’t reproduce.

16:22:48:~/tmp$ echo foo | sudo tee newfile
[sudo] Passwort für bleistift2:         
foo

16:23:02:~/tmp$ ls -l newfile
-rw-r--r-- 1 root root 4 Feb 23 16:22 newfile
