https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248536 Bug ID: 248536 Summary: periodic(8) /absolute/path/where/basename/contains-hyphens interpreted as options to mail(1) Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: danielsh@apache.org I ran «periodic /usr/local/etc/periodic/one-off» from /etc/crontab and got the following output: [[[ Subject: Cron <root@zsh> periodic /usr/local/etc/periodic/one-off mail: illegal option -- o Usage: mail [-dEiInv] [-s subject] [-c cc-addr] [-b bcc-addr] [-F] to-addr ... [-sendmail-option ...] mail [-dEHiInNv] [-F] -f [name] mail [-dEHiInNv] [-F] [-u user] mail [-d] -e [-f name] ]]] What happens: The function output_pipe() is called with a first argument of «/usr/local/etc/periodic/one-off», which then runs «eval» on the string «output=$one-off_output», which sets the variable $output to the value «-off_output» (because $one expands to nothing), and that variable is then used to build the mail command in $pipe, which works out to «mail -E -s '…' -off_output», which produces the above output. Reproduced in 11.2R, but by source inspection applies to CURRENT too. -- You are receiving this mail because: You are the assignee for the bug.help
