Why don't you just try it and see if it works?

I've never seen any shell or sed syntax that allows you to subscript a
line like this.  You should read up on awk, although there is no
simple way to do dual file processing along these lines.  (An awk
script for this would need to know it has two files to process and
read in the first one, then print it with replacements from the second
one.)

Also, if the above were to work, it would be "for i in `cat...." - the
"in" is part of "for" syntax....

Man pages are really handy for this sort of thing....

Hi Chloe,

Separated by what? Tabs? Spaces? Can the fields themselves have spaces
in them? Do you have many records, one per row? Please give a more
informative example of the file you have...

Is that supposed to be a template? What are you trying to achieve?
Replace "Chloe" with the first field and "CA" with the
second field of
the list.txt file? Create one file per row of list.txt?

If you ask vague questions all you will have are vague answers...

HTH,
Filipe

#!/bin/sh
while read NAME ADDRESS
do
sed -e"s/Chloe/$NAME/" -e"s/CA/$ADDRESS/"
<letter.txt>$NAME.letter.txt
done <list.txt

Seems sort of fragile in that the name field can't have spaces.

Hi

If your file has only 2 columns and there is no space exists in 2nd 
column then you can use this script

#!/bin/sh
FILE="list.txt"
OUTPUT="out.txt"
while read VAL

do
VAL1=$(echo $VAL | awk '{print $1}' )
VAL2=$(echo $VAL | awk '{print $2}' )

echo "DEAR: $VAL1" >> $OUPUT
echo "DEAR: $VAL2" >> $OUPUT
echo " ">> $OUTPUT

done<$FILE

if you have spaces in between your 2nd column you might have to format 
the file using awk/sed
so that there would be a valid delimeter between column1 and column2

column 1| column2 here we can use '|' as the delimeter and change awk 
statement
to awk -F '| ' '{print $1}' or something like this.

For single words space separated:

  cat list.txt | while read LINE
    do
      set $LINE
      printf "Dear: %s\nAddress: %s\n" $1 $2 >> $1.letter.txt
    done
