environment-variables

问题 I've been having quite an unusual problem. In my .bashrc file, I have set a variable to a path name with spaces in it. I had a feeling this would cause problems, but I played around with setting an alias in a similar way and got it to work like so: alias npp="\"/cygdrive/c/Program Files (x86)/Notepad++/notepad++.exe\"" Now, I thought I could use the same trick for my environment variable - export PRO="\"/cygdrive/c/Program Files (x86)\"" This worked. Kind of. [myName] $ echo $PRO "/cygdrive/c

问题 I have a simple c# application that is binding to a library compile with mingnu compiler toolset. I can easily call the functions in the library without issue. However the library calls getenv to set itself up this environment variable needs to be set for the library to work correctly so I am using Environment.SetEnvironmentVariable however the library cannot retrieve the value I have set. 回答1: getenv makes a copy of the environment variable block of the process on startup. Any subsequent

问题 I'm trying to execute a program (convert from ImageMagick, to be specific) whose parent folder exists on the path. Ergo, when I run convert from the command line, it runs the command. The following, however, fails: String command = "convert" CommandLine commandLine = CommandLine.parse(command); commandLine.addArgument(...) ... int exitValue = executor.execute(commandLine); If I specify the full path of the convert executable ( C:\Program files\... ) then this code works. If I don't do this, I

问题 When defining an environment variable (on Windows for me, maybe there is a more general guideline) set MY_TOOL=C:\DevTools\bin\mytool.exe if the tool is located on a path with spaces set MY_TOOL=C:\Program Files (x86)\Foobar\bin\mytool.exe should the environment variable already contain the necessary spaces? That is, should it read: set MY_TOOL="C:\Program Files (x86)\Foobar\bin\mytool.exe" instead of the above version without spaces? Note: In light of Joeys answer, I really should narrow
