[Help-bash] how to translate one file

[lina]

Hi,

I have one file like

a 1
b 2
c 3

and the last line of the file like :

abc

I wish to translate it to
1 2 3


Here is the script I wrote, but choked by the crucial step of translation,

#!/bin/sh

for f in dm_1.xpm ### Here I used for cause I have 10 *.xpm files, and 
they have different dictionary.
do

awk '{if(NF==7) print $1, $6}' $f | tr -d '"' | sed 's/[a-Z]/\$&\=/g'

tail -1 $f | tr -d '"'

#echo ${f%.*}

done

I attached the file below,

BTW, Thanks all for helping me in the past, for some questions I asked, 
I still need time to digest about your reply. If none immediate 
response, it did not mean I did not care about the questions I asked. It 
means I cared both my questions and your reply. Thanks again,

Best regards,
