Taking some code from previous answers, you can use this code:

while read word; do
    if [[ $word =~ ^(....)(.)$ ]]; then
        filename="yy/${BASH_REMATCH[1]}.txt"
        letter=${BASH_REMATCH[2]}
        [[ -f $filename ]] && sed -i.bak -n "/^ *csh.*$letter/p" $filename
    fi
done < xx.txt

This might work for you:

sed '/^ *chs.*A/!d' file

You need to carry forward any information from the previous question that provides specifications for this one.

This may work for you:

awk '$3 == "A"' inputfile

You can replace "inputfile" with a glob, perhaps *, in order to process multiple files as if they were cated together.

Without having a clearer indication of how you want the multiple files processed, that's the best I can do.
