Erm... no need to apoligize... technically I have to apologize for using the word "bickering" (as others have pointed out) when I was thinking about "debate" (=welll. to be honestly somewhere in my brain I was thinking "oh no... not again" when I saw Wiliam's posting the first time... ;-/ ). > I know all of these decisions have many constraints that govern them.

"bash" and "ksh93" have common ancestors (see http://mail.opensolaris.org/pipermail/opensolaris-code/2007-March/004621.html) and did influence each other's development so you have to dig a bit harder to hit the differences when porting from "bash" to "ksh93". The reverse way is a bit more bumpy since ksh93 has far more datatypes and a wider range of variable types (e.g. compound variables which can be combined with arrays which can lead to infinitly deep variable trees (and then you have "nameref" variables which can act similar C pointers)). > > to show how the script could make use of ksh93 features (your script > > would AFAIK work with both bash and ksh93, I only did some cleanup and > > some changes to use more ksh93 features (e.g. compound variable arrays > > which are AFAIK quite usefull in this case where you have label/value > > pairs (e.g. I merged the two arrays in your script into one array where > > each array element contains two values)) ... > > Thank you for this script too. It was even more educational. No problem... if you have other stuff you'd like to port (e.g. something which uses lists, arrays, trees, complex pattern matching or other complex data structures) let me now.. I'm happy to provide as many examples as you need... :-) ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) roland.mainz at nrubsig.org \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 7950090 (;O/ \/ \O;)
