$ man find-readable Matches files which are readable. This takes into account access control lists and other permissions artefacts which the -perm test ignores. This test makes use of the access(2) system call, and so can be fooled by NFS servers which do UID mapping (or root-squashing), since many systems implement access(2) in the client's kernel and so cannot make use of the UID mapping information held on the server. Mention readable by whom, so one need not check the Info manual.
Thanks, the attached fixes it - I'll push next year. Have a nice day, Berny
