Loop to remove inverted commas (") in a dataset in bash

I would like to find a way to use an iterative loop (for or while) to remove quotes (") from a dataset like the following:

"Macao,""China,Macao Special Administrative Region"",MAC

I know that there is the following way to remove them, which is actually more efficient, but it is important that it is an iterative statement in bash

sed -i -e 's/"//g' file.csv

Any idea?

>Solution :

You can use while read -r to read the lines. Use Parameter Expansion to remove the double quotes.

while read -r line ; do printf '%s\n' "${line//\"}" ; done < input
