Why "messing around" with quotations? Ich didn't see any mess.


@Klaus

I found some more strange commandline handling, please take a look to 
the following examples:


This works:
-----------
# opt="-P dvd '-C/dev/cdroms/cdrom0'"
# vdr $opt  [more parameters...]

This doesn't work:
------------------
# opt="-P'dvd -C/dev/cdroms/cdrom0'"
# vdr $opt  [more parameters...]


This works:
-----------
opt="-P vcd"
# vdr --lib=/lib/vdr $opt  [more parameters...]

This doesn't work:
------------------
opt="-P vcd"
# vdr $opt --lib=/lib/vdr  [more parameters...]


This also doesn't work:
-----------------------
opt="-P'vcd -v /dev/cdroms/cdrom0'"
# vdr $opt --lib=/lib/vdr  [more parameters...]

(message  vdr: /lib/vdr/libvdr-'vcd.so.1.2.6pre2: cannot open shared 
object file: No such file or directory)

If I modify the first line to

# opt="-Pvcd '-v /dev/cdroms/cdrom0'"

this will be accepted, also this version

# opt="-Pvcd \"-v /dev/cdroms/cdrom0\""


The whole thing is pretty unpleasant, because I need a dynamic, not a 
static command line.


regards
Alfred
