How to use sed to remove all double quotes within a file

Question

I have a file called file.txt. It has a number of double quotes throughout it. I want to remove all of them.

I have tried sed 's/"//g' file.txt

I have tried sed -s "s/^\(\(\"\(.*\)\"\)\|\('\(.*\)'\)\)\$/\\3\\5/g" file.txt

Neither have worked.

How can I just remove all of the double quotes in the file?

Answer 1

You just need to escape the quote in your first example:

$ sed 's/\"//g' file.txt
