There appears to be a bug in bash when using a variable in curly
brace expansion, e.g., {1..$n}. I have put the two following test
scripts in the attached files looper1.sh and looper2.sh:
Brace expansion is done before variable expansion:
The order of expansions is: brace expansion; tilde expansion,
parameter and variable expansion, arithmetic expansion, and
command substitution (done in a left-to-right fashion); word
splitting; and pathname expansion.
Neither pdksh (which installs as ksh using homebrew) nor dash handle either
case correctly:
Neither pdksh nor dash has brace expansion.
