heirloom toolchest has about four "personalities":
1. SVRx (default?)
2. BSD
3. Single UNIX 3
4. SUS
(The latter two are variants of POSIX)
In general, the POSIX variants are about as close to precisely
standards-conformant as you can get; unfortunately, the plain old UNIX
versions are default. I note, though, that nl presumably ought to start
numbering at 0 when specified; instead, it starts at 1 (SU3/SUS
variants), skipping the line that would be numbered 0. The old unix
version apparently didn't recognize -b.
But I figure it beats Busybox any day--and I'd rather not use GNU
bloat.
I'd rather use mksh/ksh93, but if you want a POSIX shell, the Bourne
shell beats dash on standards-conformance (after all, it *is* the
standard). mksh (when invoked as sh) is almost pure POSIX.
