using date for a file name
Hi everyone.
I've made a script which rename *.jpg files by the date: *.jpeg becomes 050713*.jpeg.
Code:
#!/bin/bash

echo Please input the YearMonthDate \(each in two numbers\).
read date
ls -l | grep .jpg | awk '{print "mv "$9" 0"'$date'$9}' > command.bash
bash command.bash
rm command.bash

This works but isn't smart i think.

Probrems:
  • $date ignores the year; 050713->50713, so i forced "0"
  • command.bash has no "#!/bin/bash" in it's top.
  • "bash command.bash" or "rm command.bash" seem unnatural.
What is the real expression which matches top of a file,
and how to execute commands made by awk commands?
Please answer to questions above.
But please do this by simple commands. (this is the only condition!)

       Install one, or many jpeg images to handheld.

       List all jpeg files and thumbnails on handheld.

       Fetch all jpeg files, or certain ones by name.

       Tries to detect if a file really is a jpeg and refuses to install it, if it is not.

       pilot-foto allows you to do multiple operations in one sync. For instance, delete test.jpg and install test.jpg.

		   pilot-foto -i MyImage.jpg
		   pilot-foto -i *.jpg
		   pilot-foto -f MyImage
		   pilot-foto -c MyImage.jpg.pdb

PROBLEMS

       Palm has not published their database format for the thumbnails. So, pilot-foto puts a generic penguin thumbnail for every image  uploaded.
       Fotos can be accessed by a named list on the handheld as well as the thumbnails. This has been tried on a couple of handhelds. It is possi-
       ble that a foreign palm or different model will not like it.

       To get a thumbnail image you can copy the jpegs to the memory card. If you copy them back to the handheld they will have  a  new  thumbnail
       that matches the jpeg.

BUGS

       If  a  jpeg  is	installed with the same name as one already on the palm you will have 2 thumbnails pointing to the same jpeg. The new jpeg
       will overwrite the old jpeg.

       If the thumbnail fails to install then the jpeg should be removed. It is not.
