EDIT: And, shouldn't that ksh version be capable to do ALL the parameter expansions we were talking about in this thread?
One could easily argue that David should have put ksh in the version output instead of sh, but that isn't what it does. David and Glenn have argued that ksh is frequently install as (or linked to) sh and that is the reason the output is the way it is.

No. The ${var//...} parameter expansion is not one of the ones defined by the standards (the ones in the standards are in all versions of ksh93). I think this expansion was adopted up from another shell (maybe bash). I also think a recent version of bash adopted printf '%(date_format)T' from ksh93.

They are present in ksh93 93u+ and later releases. I don't think they were present in ksh93 93t+.

HI Rudi -

I've escaped the single quote as well as placed double quotes around it. However, if I'm being completely honest, I'm having trouble understanding how this parameter expansion works. Would it be too much to ask if you explained to me?

Thank you.
