Package: dash Version: 0.5.5.1-7.4 Severity: normal
Hi. IMHO the shift built-in behaves incorrectly. Take an example shell script like this: #!/bin/sh echo foo shift 99999 echo bar In case 99999 > $# the shell scripts aborts. POSIX' definition of shift (http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#shift) however does not say that the shell should abort. It only says that the exit status (of the built-in) is > 0 in that case and that stderr might be used for diagnostic messagses. This bugs makes it impossible to e.g. process the positional parameters like this: while shift 1 2> /dev/null ; do domeSomethingWith $1 done Cheers, Chris. -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.39-heisenberg (SMP w/2 CPU cores; PREEMPT) Locale: LANG=en_DE.utf8, LC_CTYPE=en_DE.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages dash depends on: ii debianutils 4 Miscellaneous utilities specific t ii dpkg 1.16.0.3 Debian package management system ii libc6 2.13-4 Embedded GNU C Library: Shared lib dash recommends no packages. dash suggests no packages. -- debconf information: * dash/sh: true -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
