https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207248 Bug ID: 207248 Summary: [patch] daemon(8): Add option to redirect stdout and stderr to a file Product: Base System Version: 10.2-RELEASE Hardware: Any OS: Any Status: New Keywords: patch Severity: Affects Only Me Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: me@cschwarz.com Keywords: patch Created attachment 167080 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=167080&action=edit Patch for daemon(8) and its man page enabling IO redirection. Some applications that are daemonized using daemon(8) do not provide means to write log files. stdout / stderr is their only way to provide output. While this behavior is debatable, we already built a tool that deals with applications that do not daemonize themselves, daemon(8). Currently, daemon(8) only has a flag `-f` to redirect both stdout and stderr to /dev/null. Setting the flag causes the daemon(3) call to be called with daemon(*, 0). However, daemon(3) does not provide means to specify alternative redirection destinations. The patch attached to this bug report adds flags `-e`, `-o` and `-a` to daemon(8) that can be used instead of `-f` to redirect stderr and stdout to specified file paths. `-a` is used to toggle appending instead of overwriting the specified path. The man page has been updated to reflect the changes made to the source code. The flags have been chosen semantically and syntactically identical to `http://software.clapper.org/daemonize/` which is a tool available both in many Linux distributions and in the ports tree. However, I would like to see the features implemented in this patch in the base system. (Naturally, ) I think the code provided by this patch is much more straight forward and cleaner than the aforementioned third party tool. -- You are receiving this mail because: You are the assignee for the bug.
