[sf-lug] Talk on Shell Scripting

[Ken Shaffer]

Very nice presentation.  It got me to look around at some old files,
and was glad to see some fixes in the last few years addressed the
locale COLLATE oddities with (bash) character ranges.  [a-x] no longer
matches any upper case, even in non C locales.(well at least in the
"en_US.UTF-8", didn't check any others.  Not so glad to see the
simpler shell dash got altered a bit to allow "strange" ranges like
[A-b] --  which  used to be a syntax error, but now does exactly what
the ascii values of the chars treated as the range indicates.  Anyway,
no more defensive coding to set the locale to C in your scripts!
Things do change over time, sometimes for the better.
