mkdir code
aws lambda list-functions | \
grep FunctionName | \
cut -d '"' -f4 | \
while read -r name; do
    aws lambda get-function --function-name $name | tail -n 3 | egrep -o 'https?://[^ ]+' | sed 's/"//' | xargs wget -O ./code/$name.zip
done

I had to patch it because the output from get-function doesn't always came in the same order. I used jq as: aws lambda get-function --function-name $name | jq -r '.Code.Location' | xargs wget -O ./code/$name.zip in line 10 and it worked flawlessly.

Thank you very much!

Working flawlessly. Thanks for sharing

I used export source code w/ function Configurations.
aws lambda get-function --function-name $name | tee ./code/$name.json | jq -r '.Code.Location' | xargs wget -O ./code/$name.zip

Thank you!

It's not working for me, just generating the folder "code"; nothing else.
Thanks.

Using Wget didnt worked really well for me i instead replaced it by curl and it works well
aws lambda get-function --function-name $name | tee ./code/$name.json | jq -r '.Code.Location' | xargs curl --output ./code/$name.zip

This worked for me using git-bash terminal on windows.

mkdir -p code

#Select only matching prefix functions
grep <prefix> | \

    aws lambda get-function --function-name $name | tee ./code/$name.json | egrep -o 'https?://[^ ]+' | sed 's/"//' | xargs curl --output ./code/$name.zip
