You can do it without sed

:

string="${string/,/\\,}"

To replace all occurrences of ",", use the following:

string="${string//,/\\,}"

Example:

#!/bin/bash
string="Hello,World"
string="${string/,/\\,}"
echo "$string"

Output:

Hello\,World

You need to escape back slash \/

I'm not sure what your input is, but this will work:

echo "teste,test" |sed  's/,/\\/g'

output:

teste\test

If the line is in a file, you can use:

sed -i 's/,/\//g' myfile.txt
