comment The type command can't distinguish between an executable command and a shell script
A executable program is a file with the execute bit set on the file; if a shell script has that bit set, then to the os deems that file an executable program. That file actually doing something useful depend on other factors.

You can run qemu as a unprivileged user by having qemu drop permissions via -runas user or by creating a tap device that is owned by the unprivileged user. ip-tuntap(8) can assign ownership of tuns/taps. among other ways.

comment For input redirection, are there functional differences between bash/zsh <<<“$(<file)” and the traditional <file?
Not wanting to give a history lesson like chazelas is the reason why it is just a comment.

comment For input redirection, are there functional differences between bash/zsh <<<“$(<file)” and the traditional <file?
<<< adds a final newline, where as if < file doesn't. $(<...) also removes trailing blank lines, where as < file won't. a better comparison, functionality wise would be <file and < <(cat file) but the former is still more efficient typing wise and implementation wise.
