Challenging Shell Script

[vick Julius]

I have a folder of digital images MV1000.jpg, MV1001.jpg, MV1002.jpg,....
These images correspond to a list of hardware items. This list is in a text 
file items.txt as follow:


ID     Description              // this line can be removed from the file
500   screw driver philips
501   camera digital canon
502   laser printer samsung
etc...

The  image MV1000.jpg corresponds to the first item in the list, i.e.  500   
screw driver philips and the second image, MV1001.jpg corresponds to the 
second item in the list, i.e. 501   camera digital canon and so on.


I want to rename the images in the following way:

The name of each image should be made of:  3 letters which are the first 
letters of each word in the line from items.txt file (screw driver philips 
would be sdp) followed by the ID of the item.

For example:




MV1000.jpg  should be     sdp500.jpg
MV1001.jpg  should be     cdc501.jpg
MV1002.jpg should be      lps502.jpg



Thank you

Vick

sed 's/\([0-9]*\) *\(.\)[^ ]* *\(.\)[^ ]* *\(.\).*/\2\3\4\1/' items.txt

I'll let you do the rest.
