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"
