https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220587 Bug ID: 220587 Summary: /bin/sh Incorrect options handling Product: Base System Version: 11.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: ryan@freqlabs.com The system shell /bin/sh is consuming options after the command string when -c is used. According to the synopsis, nothing after the -c command_string should be interpreted as an option. Furthermore, passing -s as the program_name argument causes the shell to read from standard input, which is at odds with the description of the -c option in the manual and in the POSIX standard. The behavior on FreeBSD is inconsistent with the behavior on other operating systems. A NetBSD and an Ubuntu Linux system were checked, and both have the expected behavior. Observed behavior: ``` $ sh -c 'echo $0 $@' -m foo foo $ sh -c 'echo $0 $@' -s foo $ <child shell, reading commands from standard input> ``` Expected behavior: ``` $ sh -c 'echo $0 $@' -m foo -m foo $ sh -c 'echo $0 $@' -s foo -s foo ``` -- You are receiving this mail because: You are the assignee for the bug.help
