ok, I'll bite. What current Unix systems ship with a default shell that supports neither command-completion nor command-history?

- racingmars 6y agoThe one I have to use frequently is the restricted ksh environment in IBM's IVM/VIOS server, which is AIX. I believe it does log a short set of command history to a file, but it'd not available with, say, the up arrow. In general, though, I don't think any form of history is required by the POSIX shell standard, and tab-completion definitely isn't.
- ajarmst 6y agoksh93 supports both completion and history. I lost interest in looking before uncovering information about versions of ksh more than thirty years old, but neither feature is mentioned in descriptions of differences between ksh93 and predecessors, so I suspect the feature has been there for longer. Posix compliance is neither necessary nor sufficient for a reasonable colloquial definition of "shell."
