environment-variables

问题 On my node node_name I've got $JAVA_HOME and other environment variables set in /etc/profile . I'm aware (found that out) that knife ssh isn't a login shell, and so doesn't load the environment variables. Is there a way to load the environment variables without having to source it? Right now I'm forced to do knife ssh 'name:nod_name' 'source /etc/profile; echo $JAVA_HOME' I'm chaining in a few commands during knife ssh including some of the environment variables and loading the /etc/profile

问题 I'm using the Win32 function GetEnvironmentVariable to retrieve the value of a variable that I just created. I'm running Windows XP and VC++ 2005. If I run the program from within Visual Studio, it can't find the new variable. If I run it from a command-prompt, it does. I restarted VC++ but same result. I even restarted all instances of Visual Studio but still the same problem. It might get resolved if I reboot the PC but I'm curious why this is so. Here's the code that I'm using: #define

问题 I'm on a Win 7 machine using Powershell 4.0 PS C:\> $psversiontable Name Value ---- ----- PSVersion 4.0 WSManStackVersion 3.0 SerializationVersion 1.1.0.1 CLRVersion 4.0.30319.42000 BuildVersion 6.3.9600.18728 PSCompatibleVersions {1.0, 2.0, 3.0, 4.0} PSRemotingProtocolVersion 2.2 See command line exercise below. The dll exists. The environment variable exists and has the correct path. When I use the the environment variable with Test-Path , it incorrectly reports $false . When I use a string

问题 We use log4net for logging. I am wondering if it is possible to use environment variables when specifying the log level. The motivation is simple - our QA folks will not have to edit the config files, they will just set certain environment variable once. In short: We do not want to set the log level in the config file to some constant value, because the same build is run by different teams and different teams have different, but rarely changing logging needs. Right now, after every

问题 The UNIX "/usr/bin/script" command will create a running transcript of your shell session (see "man script" for more info). However, when inside a script instance, it seems to forget the parent shell's env vars, aliases, etc. The following example demonstrates how the "ll" alias I define is ignored inside "script": zsh> mkdir temp zsh> cd temp zsh> alias "ll=ls -alF" zsh> ll total 24 drwxr-xr-x 2 me mygroup 4096 Feb 18 13:32 ./ drwxr-xr-x 28 me mygroup 8192 Feb 18 13:32 ../ zsh> script a.out
