Forgive me for promoting this that I wrote:

csvquote: https://github.com/dbro/csvquote

Especially for use with existing shell text processing tools, eg. cut, sort, wc, etc.

Yes, this is what csvquote does. It does nothing else, just this so that programs like awk, sed, cut, etc. can work properly.

That is correct, the data needs to be simple where the delimiter characters are never embedded inside a quoted field. I wrote a simple (and fast) utility to ensure that CSV files are handled properly by all the standard UNIX command line data tools. If you like using awk, sed, cut, tr, etc. then it may be useful to you.

Using it with the first example command from this article would be

  csvquote file.csv | awk -F, '{print $1}' | csvquote -u

By using the "-u" flag in the last step of the pipeline, all of the problematic quoted delimiters get restored.

There is a small program I wrote called csvquote[1] that can be used to sanitize input to awk so it can rely on delimiter characters (commas) to always mean delimiters. The results from awk then get piped through the same program at the end to restore the commas inside the field values.

In principle:

  cat textfile.csv | csvquote | awk -f myprogram.awk | csvquote -u > output.csv

Also works for other text processing tools like cut, sed, sort, etc.

Good idea! Looks similar to something I wrote called csvquote https://github.com/dbro/csvquote , which enables awk and other command line text tools to work with CSV data that contains embedded commas and newlines.

To simplify working with CSV data using command line tools, I wrote csvquote ( https://github.com/dbro/csvquote ). There are some examples on that page that show how it works with awk, cut, sed, etc.
