want you to look at the files raw_data, raw_data2 and more_data. These files contain valid data to transform. What regular expression could you create that would match all the lines in these files.
Experiment on the command line. Do not change your script yet. Figure out a regular expression that will match all the lines in these files
When you have a regular expression that works, try it on the files bad_data, more_bad_data and additional_bad_data. What you want to look for is any lines that do not match your regular expression. HINT: Look at the man page for grep and look for an option that will select non-matching lines.
Need help with attached assignment above. Thank you.
