I have ~2k files that I want to extract 12 of 26 columns and save the extracted information into a new file.  I have been doing this for individual files using cat oldfile.csv | grep -v = | cut -f 1-4,9,14,15,19,21,22,24,26 > newfile.csvThere must be a way to do all files with one Unix series of commands.Any help is greatly appreciated
