Hi Tiger,
I took a quick look at epubchinesecopy.desktop and noticed the following line:
Exec=/media/mmcblk0/p1/Programs/_epubchinese/epubstyleinstall.sh
which should be:
Exec=/media/
mmcblk0p1/Programs/_epubchinese/epubstyleinstall.sh
I am not sure if you need to use the full path for the fc-cache command, so /usr/bin/fc-cache. I am also not sure if you need the reboot in the copy script?
Did you install
rxvt that was ported by GregorRichards? It opens a terminal window that allows you to check if the .sh files are correct.
Good Luck!
