The above busybox behavior implies that if you write a robust script like this for coreutils, that it is not portable to busybox: base=$(basename -- "$path") That also implies that we can't change the behavior. Because there is an optional suffix parameter, one can't know which behavior is required for the above example. I suppose one could choose based on POSIXLY_CORRECT. Note solaris behaves like busybox and openbsd behaves like coreutils. cheers, Pádraig. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
