I probabably owe an explanation for the script example attached to the
previous message.
Variable 'foo' contains the output from a dbus-send command.
Function `f' is supposed to return the 'fps' of an mjpeg video stream
with a 1920x1080 resolution.
Running the script under dash does that for me and so did busybox
ash, until recently. What I now have to do is to identify all scripts
that do things like:
IFS=":$IFS"
^^^^
and replace the marked part with verbatim <space><tab><newline>. And
that will keep me busy for a while, with the uncertainty that I didn't
locate all such places.
Cheers,
