Previously we talked about how to submit a Google Form by the curl command.

• Submit Google Forms by curl command

In the url, we have to encode the special characters such as whitespace. In shell script, we could do string replace as follow.

${VariableName//Pattern/Replacement}

Here is an example.
string_replace.sh

#!/bin/sh

text="Hello World"

echo "${text}"
echo "${text// /%20}"

Check it out.

 

So now if you integrate the Google Forms submission in your backend, you could make sure the whitespace are all replaced by %20.

Done =)
