Are you on windows? (if so I don't know) or on UNIX/linux?
If you're on UNIX or linus you could use sed.
Somethign like: (this is untested so YMMV)
for FILE in *.txt; do
if sed 's/ABCD/WXYZ/g' < $FILE >$FILE.new; then
mv $FILE.new $FILE
else
echo Pattern not found or other error in $FILE.
rm $FILE.new
fi
done
If you hav Cygnus installed on your windows machine that might
work also.

| (...) or, if you have perl (windows or unix), you can do this: perl -i.bak -p -e 's/ABCS/WXYZ/g' *.txt which will create a backup (file.txt.bak) before changing all 'ABCD' to 'WXYZ'. :) Dan (22 years ago, 18-Dec-02, to lugnet.off-topic.geek)
