powershell - 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

I don't want any output from GPG to be seen on the main console when I'm running the script.

Due to my noobness in PowerShell, I don't know how to do this. I searched Stack Overflow and googled for a way to do it, found a lot of ways to do it, but non of it worked.

The "> $null" for example has no effect. I found the --quiet --no-verbose options for GPG to put less output in the console, still it's not completely quiet, and I'm sure there is a way in PowerShell too.

Answer 1

尝试将输出重定向到Out-Null。像这样，

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

Answer 2

尝试像这样重定向输出：

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

Answer 3

它是这个问题的副本，其答案包含不同方法的时间测量。

结论：使用[void]or > $null。
