Can I grep each file of directory and save output to one file? Example code included

Question

I am running a grep command on each file in a directory. I want the outputs to be appended into the same file. Is this possible?

Here is what I am using unsuccessfully:

for f in /directory/*.txt
do
grep -Eo "[0-9]+\.[0-9]+" $f >> one_output_file.txt
done

I am grepping out a number from each file and I want the numbers to be listed together in ONE output file. Possible?

Thanks!

Why not drop the for loop and do

grep -Eoh "[0-9]+\.[0-9]+" /directory/*.txt > one_output_file.txt
