decode base64: invalid input

Question

Trying to decode base64 file on GNU/Linux, I get \"base64: invalid input\".

$ base64 test.zip | base64 -d > test2.zip
base64: invalid input
$ ll test*
-rw-r--         


        

Answer 1

If you're doing this on a mac, your version of base64 might not have the flexibility to handle ignoring garbage. If you brew install coreutils, you'll have the gbase64 utility and use it as Joe has described.
