On Tuesday, January 17, at 7 P.M. Detroit, MI time,
http://www.semibug.org/ will have a presentation on shell scripting
by our long time contributor Nick Holland. The Jitsi link is:

This will be a short presentation with a questionand answer session
at the end. I am pretty sure this is Korn Shell specific.

See you there

Kind regards,
