Subject: bug in ${##} expansion
Date: Fri, 11 Mar 2011 12:07:20 -0700 [thread overview]
Message-ID: <4D7A72E8.5070909@redhat.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 420 bytes --]
POSIX requires ${#parameter} to expand to the length of parameter as a
string. It also requires that ${parameter#word} substitution have a
word (that is, ${parameter#} with a missing word is a zsh extension).
Therefore, this should output 2, not 11:
zsh -c 'set 1 2 3 4 5 6 7 8 9 10 11; echo ${##}'
