Running 2.4.7 on Solaris.
I have a function that accepts three arguments, the last of which is
optional; if omitted, I supply a default. Here's what's working:
AddToFunc MyFunc
+ I PipeRead 'BD=$2; BD=${BD:-4}; ... '
If I try to shorten it to this:
+ I PipeRead 'BD=${2:-4}; ... '
then BD is always 4 ($2 is seemingly ignored). "sh" is apparently
satisfied (no "bad substitution" error). Expected? Wrong syntax?
