to get images from an SD card labeled CANON_730 to a local directory

 NOTE: must change to the directory where the files go BEFORE executing script
 NOTE:  "/Volumes" will need to be replaced with the mount point used on your system, 
in Linux this will vary depending on your distribution and configuration. 
If you have an automatic mounting daemon running look for the mount with a "df -h".  
Recommend mounting manually:  mkdir -p /home/luser/SDCARD ; sudo fdisk -l ; mount /dev/sdX /home/luser/SDCARD" 
Recommend creating a "bin" directory and adding it to your path in your .bashrc file (see this site for examples).
Create the script in your bin directory and "chmod 740 scriptname".   Type "which scriptname", if it appears, it'll work.

--> cat ~/bin/getnikon

 if you have a CANON it changes directories monthly...
