Subject: Parameter substitution bug
Date: Mon, 21 Jan 2013 13:36:07 -0800	[thread overview]
Message-ID: <CAPnksqRxUvwGGQwXBPVj-yrA8a18nmLctZGD0BtBnh_vC-Muhg@mail.gmail.com> (raw)

Strangely I ran across this issue in the real world: A doubly nested
parameter substitution with an inner glob pattern (breath) fails /only
when in double quotes/! That is, these two expressions produce
different results:

${f%${f#?}}   --vs--  "${f%${f#?}}"

Strangely, that is the simplest case I get to fail.

The following script walks through the issue, and if run with bash,
ksh, or busybox exhibits those two expressions as producing the same
result.
