Public bug reported: Binary package hint: dash
On feisty, dash is installed with a symlink to /bin/sh. This breaks POSIX 1003.1 compliant scripts as demonstrated below: [EMAIL PROTECTED] dash $ x=3 $ echo $(( x + 4 )) dash: arith: syntax error: " x + 4 " $ echo $(( $x + 4 )) 7 As stated in the online version of 1003.1 (http://www.opengroup.org/onlinepubs/009695399/): If the shell variable x contains a value that forms a valid integer constant, then the arithmetic expansions "$((x))" and "$(($x))" shall return the same value. dash clearly violates the standard here. I have read all of the "bash vs dash" flame wars. This isnot about bash doing the right thing, but about dash doing the wrong thing. This breaks, amongother things, the canonical use of "while getopts ..." followed by "shift $((OPTIND - 1))" as recommended by many books stressing POSIX scripting. ** Affects: dash (Ubuntu) Importance: Undecided Status: Unconfirmed -- dash as /bin/sh breaks POSIX 1003.1 scripts https://bugs.launchpad.net/bugs/118021 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
