Package: ksh Version: 93u+20120801-1 Severity: normal ksh93 and mksh behave differently:
xvii% ksh93 -c 'echo $((010))' 8 xvii% mksh -c 'echo $((010))' 10 breaking the needed compatibility with each other since they are both /bin/ksh alternatives, and valid "#!/bin/ksh" scripts should behave consistently with both shells. According to Thorsten Glaser (the mksh maintainer), the bug is in ksh93[*]: |ksh93 can break scripts with "#!/bin/ksh" because interpreting |leading-digit-zero numbers as octal is a *very* recent change, |and is *known* to break existing scripts. Not the other way round. [*] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=732509#25 Note: ksh can still have some POSIX compatibility mode when run as sh, like other shells like mksh (actually the lksh version), bash and zsh. -- System Information: Debian Release: jessie/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.12-1-amd64 (SMP w/2 CPU cores) Locale: LANG=POSIX, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages ksh depends on: ii libc6 2.17-97 ksh recommends no packages. ksh suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
