Bug ID: 274650
Summary: sh does not accept -- after -c
Product: Base System
Version: 13.2-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: b...@freebsd.org
Reporter: guil...@hadrons.org
After having seen a similar change implemented for glibc, I did the same in
dpkg to make its shell invocations more robust and avoid missparsing in case a
command starts with a «-» (which would be very unusual, but…). See
<https://git.dpkg.org/cgit/dpkg/dpkg.git/commit/?id=f013195c70995235340e99107058f591175f0a57>.
Just noticed afterwards that this did not work on FreeBSD's /bin/sh:
,---
$ sh -c -- "echo \$0" name arg
echo $0: --: not found
`---
This though seems to work fine on posh, dash, ksh93, bash, and the default sh
on NetBSD, OpenBSD, Solaris and macOS. But neither on sh, ksh nor bsh on AIX
7.3.
For now I guess I'll need to make its usage conditional on the system.
