如何使用Bash将文本文件转换为CSV

Question

I've a text file with thousand of lines in it (each line has an email address) and I'd like to convert those to a CSV file using bash. The problem is I'm not well versed with Bash, so not sure how to go about doing it.

Any suggestions?

EDIT: File example:

email@meail.com
email2@meail.com
email3@meail.com
email4@meail.com

Answer 1

This is ugly but it should work:

while read email; do echo '"'${email//\"/\"\"}'"'; done < inputfile.txt > output.csv

This escapes " with "" which is how CSVs are escaped in Excel land.
