Help renaming files

Hi gurus!

I have this script...

Code:

#!/bin/bash

LIST='ls *.pdf'
for i in $LIST ;
#for file in originals/*.pdf
do
	gs -r300x300 -sDEVICE=tiffgray -sOutputFile=albara.tif -dBATCH -dNOPAUSE $i
	tesseract albara.tif albara -l spa
	cat albara.txt | grep -A 1 Data | tail -1 | cut -c 1-10 | sed -e "s/.*/mv $i mod\/&.pdf/" > execute; sh execute && rm -f execute
	rm albara.txt
	rm albara.tif
done

1. the script list all PDF files in a directory
2. transform it to TIFF
3. recognizes all the text with tesseract
4. changes the original name with the first 10 characters
5. finally deletes the temp files

The problem is in the step number 4 and the 10 characters treatment. If the 2 lines 'grepped' are like this:

Code:

  Número / Data
  1001114166 x 10.11.2009

No problem, finish ok.

But if the two line are like this:

Code:

  Número / Data
  10111416 x 10.11.2009

No works!

How can I solve this?

Thank's!

You can see that the problem is that cut is cutting the 10 characters, so if the number is only 8 chars long you are cutting 2 chars extra, right?
Just cut the characters before the first space like this:

Code:

cut -f1 -d " "

or use sed for the required purpose.

the LIST=`ls` is superfluous

Code:

for i in *.pdf
do
   etc...
done

you need to explain better what you are trying to do.
what's the 10 characters about?
