Subject: PATCH: reverse string subscripting
Date: Thu, 5 Apr 2001 13:22:12 +0200 (MET DST) [thread overview]
Message-ID: <200104051122.NAA06140@beta.informatik.hu-berlin.de> (raw)
This is from the debian bug list:
% a=abcd
% echo $a[1,(r)d]
didn't work, because it stopped one character too early trying to find
the matching substring for `d'.
Bye
Sven
