The [[ builtin is a kornism and bashism with better-defined semantics than [ (a.k.a. test). If you want your script to be portable as in work with all POSIX-conformant shell script interpreters, you should use the more limited [.
As regards dash and POSIX conformance, according to the current manpage for dash:
Quote:
The current version of dash is in the process of being changed to conform with the
POSIX 1003.2 and 1003.2a specifications for the shell.
Unlike a number of other shells, I do not believe that dash has passed the VSC-PCTS2003 POSIX Certification Test Suite.
It is easy to claim POSIX conformance but a testsuite is the only valid indicator of conformance.
