As I started tinkering with codesign (the commandline utility from Apple to sign code with and test if code has been signed), I ran into the issue that when trying to redirect the output to a file, nothing did get redirected.
For example:
codesign -dv --verbose=4 MyApp.app > output.txt
resulted in a zero byte file.
Then I recalled the good old days, and remembered the stdout vs stderr misery and found that the following actually does work:
codesign -dv --verbose=4 MyApp.app &> output.txt
(effectively outputting both stdout en stderr to the output file)
