Can I use this

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...

Dear: Chloe Address: CA

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

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.
