Argument to start_daemon, use of --
in [Debian]
|
From: Malte Forkel on 1 Aug 2010 10:10 Hi, The example init script init.d.lsb.ex provided by dh-make 0.46 contains this call to start_daemon: start_daemon -p $PIDFILE $DAEMON -- $DAEMON_OPTS This always passes "--" as first argument to my daemon. Wouldn't start_daemon -p $PIDFILE -- $DAEMON $DAEMON_OPTS be the proper call? I haven't found a reference to "--" in the LSB init function documentation, but the implementation of start_daemon in /lib/lsb/init-function (from lsb-base) handles "--" explicitly. The use of "--" is documented in bash(1) though. Is this a convention? What status has it?

If the -- is in a Debian specific script from a maintainer I would, and post the proof that -- is being passed to the executable before _OPTS and ask them if this is intended and then explain to them how it breaks whatever it breaks and point to the man page. -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

It does seem that way to me too. > I haven't found a reference to "--" in the LSB init function > documentation, but the implementation of start_daemon in > /lib/lsb/init-function (from lsb-base) handles "--" explicitly.

It was a convention and is now a standard. http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap12.html#tag_12_02 Guideline 10: The argument -- should be accepted as a delimiter indicating the end of options. Any following arguments should be treated as operands, even if they begin with the '-' character. The -- argument should not be used as an option or as an operand. It marks the end of option argument processing. Subsequent arguments should not be treated as options even if they start with a dash. This enables processing of files that begin with a dash. Like this for example: $ touch ./--help $ rm -f -- --help Bob |
