问题 The command gci env:ApiSecret | ConvertTo-Json works to return a long string, the API secret for Twitter, which is truncated without the pipe to JSON. However, the JSON is rather spammy.

问题 I seem to be able to create environment variables that execute commands; like this: $ cat ./src FOO="echo" $ . ./src $ echo $FOO echo $ $FOO hello hello $ Is there a way I can modify that environment variable so that it prefixes the setting of another environment variable before the command?
