Correct in the sense of using arrays to build up a command line, not in
a sense of The One And Only Solution (tm).

Well, not much, except that I would do it this way:
PLUGINS[${#PLUGINS[*]}]="-Psoftdevice -vo xv:full -ao
alsa:mixer:pcm=default"
For a more complex (and a bit constructed) case:
PLUGINS="$PLUGINS -P\"hello --aaa=\\\"A B C\\\"\""
or
PLUGINS="$PLUGINS -P'hello --aaa=\"A B C\"'"
or
PLUGINS[${#PLUGINS[*]}]="-Phello --aaa=\"A B C\""
or
PLUGINS[${#PLUGINS[*]}]="-Phello --aaa='A B C'"
Arrays have the advantage that they spare one level of quoting, don't
need eval, and are a bit more 'ordered', but on the other hand are
bash-only, and cannot be exported to sub-shells.
(runvdr extreme has a quoting function, so you do it with even less
quoting like this: AddPlugin hello --aaa="A B C")
Cheers,
Udo

What makes that "correct"? Just sounds like a different (and more
complicated, ..I guess) way to accomplish the same end result, but no
more "correct" then using double/single quotes.
I'm no bash expert but STRING="$STRING -P'asdf arg'" works equally as
well as ARRAY=( "${arr...@]}" ) in my experience. What am
I missing?

The correct way to place every array element as one parameter, without
doing any additional whitespace separation, is this:
"$vdrbin" -L "$vdrlib" "${vdrpl...@]}"
In contrast, "${vdrplug[*]}" merges all to one parameter, ${vdrpl...@]}
does another whitespace separation run.
runvdr extreme also uses a bash array for building the command line.

Udo

Re: [vdr] VDR plugin options
Use double-quotes to surround your plugins and single-quotes for plugin options. For example: VDR="$vdrbin -L $vdrlib" PLUGINS="-Pfemon -P'softdevice -vo xv:full -ao alsa:mixer:pcm=default'" eval "$VDR $PLUGINS" & ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
[vdr] VDR plugin options
Hello,
in this example of starting VDR in a script some options are passed to
the softdevice plugin:
$vdrbin -L $vdrlib -Pfemon -P"softdevice -vo xv:full -ao alsa:mixer:pcm=default"
Now I want a variable or array at the top of the script so I could
easily add, remove and comment plugins... rewriting the above example:
vdrplug=(-Pfemon
-P"softdevice -vo xv:full -ao alsa:mixer:pcm=default"
)
$vdrbin -L $vdrlib ${vdrpl...@]}
I have tried numerous ways of quoting and escaping the softdevice line
but I always get one of:
1. VDR tries to start a plugin called: "softdevice
2. VDR interprets -v in -vo as VDR video directory option and fails
because there is no directory "o"
Can anyone help me with writing this? I use vdr 1.6.0, thanks,
