问题 I know I can read environment variables like this: Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments); However, it would be really helpful to me if I could do something like this: Environment.ExpandEnvironmentVariables(@"%MyDocuments%\Foo"); Is there an environement variable that equals SpecialFolder.MyDocuments? I also tried to do something like this, but this doesn't lead to the expected result: Environment.ExpandEnvironmentVariables(@"%USERPROFILE%\My Documents\Foo"); This

问题 HTTP_AUTHORIZATION seems to be a server side environment variable, but what values can it be? Are there examples? Is it set by some HTTP headers? Also, how does it look like on the browser side when it asks for username and password (is it an HTML form or is it a popup box that asks for username and password (which is modal and so if not clicking OK or Cancel, then the browser cannot be click on)). Usually, a user login form will POST to the server with POST variables such as username=peter

问题 Okay I know there is a bash debugger. But what I'm seeking is if I had an environment variable in one of my startup scripts and I don't know how it was set or where it might be, is there a way to find it other than exhaustively searching the scripts? I mean is there a mechanism/tool that provides such a thing? Does bash keep track of variable setting locations? Even though this might not seem very important but it crossed my mind the other day when I was helping a friend install OpenCL and

问题 I am writing some functions for doing repeated tasks, but I am trying to minimize the amount of times I load the data. Basically I have one function that takes some information and makes a plot. Then I have a second function that will loop through and output multiple plots to a .pdf. In both functions I have the following line of code: if(load.dat) load("myworkspace.RData") where load.dat is a logical and the data I need is stored in myworkspace.RData. When I am calling the wrapper function

问题 I am working on a task that involves building a docker image with centOs as its base using a Dockerfile . One of the steps inside the dockerfile needs http_proxy and https_proxy ENV variables to be set in order to work behind the proxy. As this Dockerfile will be used by multiple teams having different proxies, I want to avoid having to edit the Dockerfile for each team. Instead I am looking for a solution which allows me to pass ENV variables at build time, e.g., sudo docker build -e http
