As crazy as this is going to sound... you can't count on all POSIX tools to be present anymore. VMs or containers are apparently being built or distributed without some of the tools. See, for example, "Fedora 42 doesn't have awk: how to deal with autoconf subst?," <https://lists.gnu.org/archive/html/bug-gnulib/2025-04/msg00127.html>. (Fedora 42 was _not_ the problem. The problem was the vm or container lacked some of the text tools). Jeff
