swf player aware of file changes [closed]

Question

I'm looking for a .swf player that would reload an already opened file if its content changed. Alternatively one that would work in one-instance only way so when I call it again with a new file I would have the desired effect. As in :

gnash first_file.swf
... 
gnash new_file.swf

ending up with only one window.

I have an overly complicated solution ready with a bash script checking the file size changes, killing old instance and reinitializng the program but I'm curious whether there is a more elegant solution.

Answer 1

My solution is

sudo apt-get install incron
echo "my_username" | sudo tee -a /etc/incron.allow # allow my_username to run incron
incrontab -e

add the following to incrontab:

/home/my_username/path/myfile.swf IN_MODIFY /home/my_username/path/run.sh

and the run.sh contains

killall gtk-gnash
gtk-gnash /home/my_username/path/myfile.swf

Does the job, I hope this helps someone in at least indirect way. Incron is a very powerful tool.
