Suppress console output in PowerShell

Question

I have a call to GPG in the following way in a PowerShell script:

$key = & \'gpg\' --decrypt \"secret.gpg\" --quiet --no-verbose > $null

Answer 1

It is a duplicate of this question, with an answer that contains a time measurement of the different methods.

Conclusion: Use [void] or > $null.

Answer 2

Try redirecting the output to Out-Null. Like so,

$key = & 'gpg' --decrypt "secret.gpg" --quiet --no-verbose | out-null

Answer 3

Try redirecting the output like this:

$key = & 'gpg' --decrypt "secret.gpg" --quiet --no-verbose >$null 2>&1
