environment-variables

问题 I have an msbuild project file that is used for building several C++ projects (*.vcproj). Here's a part of a typical project file, in which global environment variables for the build are overridden as properties: <PropertyGroup> <MYBINDIR>d:\buildsysroot\bin</MYBINDIR> <MYLIBDIR>d:\buildsysroot\lib</MYLIBDIR> ... </PrpertyGroup> <ItemGroup> <MyItems Include="d:\buildsysroot\myproject\myproject.vcproj"/> </ItemGroup> <Target Name="Release_x64"> <VCBuild Projects="@(MyItems)" Configuration=

问题 I for example I've got webserver's root directory /var/www/ . And user's home directory: /var/www/testuser/ . I also have basic authorization setted up, so there is a user with username testuser which successfully authorized. How can I check if the testuser is browsing their home directory by the means of webserver alone? This is how far I've got: # Getting "testuser" out of "/testuser/echo.php" SetEnvIf Request_URI ^/(.*)/ URI_HOME=$1 # Getting base64 encoded part out of Authorization header

问题 I do want to start a batch job that generates a jobid as output. How can I save the jobid as environmental variable and reuse it in the cshell script? Thanks and best wishes, Rollz 回答1: Use backticks to substitute the output of a command into the command line. To set an ordinary variable: set varname = `start_batch_job` To set an environment variable: setenv varname `start_batch_job` You should generally avoid scripting in C-shell, it has lots of problems that make it poor as a scripting

问题 I have spark installed. And, I can go into the bin folder within my spark version, and run ./spark-shell and it runs correctly. But, for some reason, I am unable to launch pyspark and any of the submodules. So, I go into bin and launch ./pyspark and it tells me that my path is incorrect. The current path I have for PYSPARK_PYTHON is the same as where I'm running the pyspark executable script from. What is the correct path for PYSPARK_PYTHON ? Shouldn't it be the path that leads to the

问题 I'm trying to set the environment variable of my .bashrc using Spyder; in other words I'm looking for a python command that reads my .bashrc . Any idea? 回答1: .bashrc should automatically be loaded into the environ on login import os print os.environ if you wanted to create a dictionary of values from a bash source file you could in theory do something like output = subprocess.check_output("source /path/to/.bashrc;env") env = dict(line.split("=") for line in output.splitlines() if "=" in line)

问题 In vbscript, how do I run a batch file or command, in the current cmd prompt window, without starting a new process. For example. According to script56.chm (the vbscript help apparently) Windows Script Host Run Method (Windows Script Host) "Runs a program in a new process" So if I have code that uses that e.g. a VBS file, and a BAT file. An environment variable g has the value abc g=abc from that command window, The VBS file calls the BAT file with windows scripting host Run. The bat process

问题 I have several global environment variables set in /etc/environment on my target machine that I need to present when running some Ansible tasks. E.g. MY_VAR=Some global variable The value of these global variables are not known to Ansible so I can't use the environment functionality. Example task: - shell: echo MY_VAR is $MY_VAR register: my_var - debug: msg={{ my_var.stdout }} The output I get is MY_VAR is where I would like it to be MY_VAR is Some global variable . I understand that this is
