There is a table with data.
./result_4_0.txt
./result_4_45.txt
./result_4_45.txt
./result_4_0.txt
I want to create two columns from numbers. How can I replace "./result_" "_" ".txt" just with space. I tried before sed but it does not work together with dot or slash.
file="filename.txt"
while IFS= read line
do
done <"$file"
