Subject: [BUG] quoted substring parameter expansion ignores single-quotes in the arg
Date: Tue, 26 Sep 2017 05:41:48 +0200	[thread overview]
Message-ID: <20170926034148.ohemy3jubd2nskyj@gmx.com> (raw)

To test that the single quotes are considered ordinary chars when
double-quoting the parameter expansion:

$ dash -c "a=\\'a\\'; echo \"\${a%'}\""

The result is surprising and non consistent with a non double-quoted
expansion where the single-quotes act as quotes:

$ dash -c "a=a%; echo \${a%'%'}"

Additionally the manual states that the arg to substring processing is
processed as an ordinary word (as probably POSIX too).

Regards
