I want to use $var in
a shell brace expansion with a range, in bash.
Simply putting {$var1..$var2}
doesn't work, so I went "lateral"...
The following works, but it's a bit kludgey.
# remove the split files
echo rm foo.{$ext0..$extN} rm-segments > rm-segments
source rm-segments
Is there a more "normal" way?
