Hello,

I want to run a script to rsync local files to a NAS mounted to
/mnt/music. Sometimes the NAS is not running, and I want to prevent the
script from writing to the mount directory:  is there any easy way to
prevent this?

Thanks,

C

if [ -f /mnt/music/somefile ]
then
   # run your script here.
fi

hey, cool.  I wouldn't have expected anything like this!

another alternative, since it's likely that the contents of /mnt/music could
change (I know mine does), why not do this.

umount /mnt/music
touch /mnt/music/SENTINEL


if [ -f /mnt/music/SENTINEL ]
then
        echo "Music share is not mounted!"
        exit 1;
fi

#run your script here

the only way SENTINEL will appear is when the NAS is *not*
mounted. And this protects whatever you are using as your SENTINEL
from inadvertent deletion.

A

then do

That's an excellent suggestion.  Way cool!
