Which is also why the "[[" is found to work across all kindles - they are all Busybox which supports that syntax since about the same time (2002) Bash adopted it from ksh88.
The problem in this thread came about from off-kindle builds using something other than Bash (specifically here, sh is linked to dash rather than bash).
Developers here just need to know that sometimes they have to populate a chroot or linux-vserver instance with the things a development script expects. (I.E: Not everything "sh" will work under "dash" and not everything Bash-3 will work under Bash-4.)
Hmm... Where did I put my Linux Poker link?
