Subject Re: [jira] Created: (DERBY-677) ksh scripts should be written in a more portable way
Date Thu, 03 Nov 2005 18:50:53 GMT
To my knowledge, ksh-scripts are Korn-shell scripts, *not*
Bourne-shell scripts. Since Bourne-shell is the most widely used
shell, one could add bourne-shell scripts to Derby (.sh) , but one should not
require Korn-shell scripts to be Bourne compatible.
