Package: dash Version: 0.5.7-4+b1 Severity: normal Dear Maintainer,
In multi-line string literals, a line which starts with a $()-style subshell which outputs an empty string will have its trailing newline stripped. For example, this code: echo " $(echo '') hello $(echo '') world" will output " hello world", when other shells I've tried (zsh, bash, ksh) all output: " hello world" I haven't looked at what posix says about this particular issue, but the behavior of all the other shells looks way more sensible in my opinion. If they're actually wrong and dash implements posix correctly, feel free to ignore this issue. -- System Information: Debian Release: 8.11 APT prefers oldstable-updates APT policy: (500, 'oldstable-updates'), (500, 'oldstable') Architecture: amd64 (x86_64) Kernel: Linux 3.16.0-5-amd64 (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages dash depends on: ii debianutils 4.4+b1 ii dpkg 1.17.27 ii libc6 2.19-18+deb8u10 dash recommends no packages. dash suggests no packages. -- debconf information: * dash/sh: true
