I am trying to understand cut better and moving cut data to another file. I have a file called numbers with two columns. Each column is separated with one tab.
I am trying to swap the columns by using the cut command and saving the cut command output to another file. I have no problem cutting field 2 and saving the output to the copynumber file. But I don't know how to cut field 1 to field 2 in the output file.
I am looking for solutions that only use bash shell scripting rather than any other languages like awk.
