> Same reason why tcsh and ksh didn't get traction, and they even have merit to them. In the world of enterprise Unix, ksh is king. It is used even for "serious" applications, not only as the sysadmin's glue of choice (the company where I work at was using, in 2009, a HR payroll application written in ksh. Had they not outsourced accounting to a third party, they would probably still be using it today). Granted, "legacy" Unices are being slowly obsoleted by Linux, but ksh lives on. It would be unthinkable for RHEL or SLES to deprecate ksh and leave it out of the distribution - enterprise customers would probably think this is some kind of a bad joke.
