Wed Aug 23 08:19:08 IDT 2017 ============================ I have a report that Alpine Linux uses BusyBox for its utilities. In particular, the BusyBox ls does not have a -f option. This option is needed in at least one of the tests. Install coreutils on your Alpine Linux system: apk add coreutils in order to get a fully POSIX-compliant ls. Arnold Robbins arnold@skeeve.com
