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: b...@freebsd.org
Reporter: danie...@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.
