Package: posh Version: 0.12.3 Severity: normal Dear Maintainer,
$ env -u a posh -c 'echo $((a))' posh: : unexpected `end of expression' $ env a= posh -c 'echo $((a))' 0 I can't see why posh would return an error in the first case and not the second. $ env a=1+1 posh -c 'echo $((a))' 2 $ env a=b b=3 posh -c 'echo $((a))' 3 Note that in all the above the behavior is unspecified by POSIX (as per my reading of the spec). Variables have to contain "valid integer constants optionally including a leading plus or minus sign" (though I'm not too sure about the empty/unset case because of the http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap01.html#tag_17_01_02_01 section) Dash: $ a=1+1 ash -c 'echo $((a))' ash: 1: Illegal number: 1+1 $ a=b b=1 ash -c 'echo $((a))' ash: 1: Illegal number: b $ a= ash -c 'echo $((a))' 0 -- System Information: Debian Release: jessie/sid APT prefers testing APT policy: (500, 'testing'), (50, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.12-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages posh depends on: ii debconf [debconf-2.0] 1.5.52 ii libc6 2.18-4 posh recommends no packages. posh suggests no packages. -- debconf-show failed -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
