Why must you use a RegEx? Why is a simple command like [`wc`](https://en.wikipedia.org/wiki/Wc_(Unix)) unacceptable? – Dour High Arch Jul 04 '19 at 17:01
@DourHighArch actually we are using a tool to get data from a source and transform into valid CSV file but we need to get the count and store in a table as a column so for this regex is very convenient as per our requirement – Rahul Varma Jul 04 '19 at 17:28
