$ dash -c 'test a = a -a b = b ; echo $?; [ a != a -o a = b ]; echo $?'

  WTF is going on please ? -a and -o are prefectly supported (at least
in the unstable's dash)

  And FWIW in the last POSIX copy I own, in the shell and utilities
  * test -a
  * test -o
  * test ( )
are XSI (X/Open System Interfaces) optional features, that unlike what
Thomas pretend are properly documented.

  I agree we would like those XSI extensions to be implemented in our
/bin/sh shells. But AFAICT dash complies, even for the () grouping:

  $ dash -c 'test \( a = a -o b = 1 \) -a c = c ; echo $?'

  How come no-one even *bothered* to check. I have my plate full with
