Ruby Environment Variables
Ruby interpreter uses the following environment variables to control its behavior. ENV object contains a list of all the environment variables currently set.
| variable | description |
|---|---|
| DLN_LIBRARY_PATH | Dynamic load module search path. |
| HOME | When no arguments are passed to the Dir :: chdir, to move to the directory. File :: expand_path also be used to extend the "~." |
| LOGDOM | When no parameters are passed to the Dir :: chdir not set the environment variable HOME, to move to the directory. |
| PATH | Search path execution of the child process, and after a specified -S option, search path for Ruby programs. Each path separated by a colon (in the DOS and Windows separated by semicolons). |
| RUBYLIB | Library search path. Each path separated by a colon (in the DOS and Windows separated by semicolons). |
| RUBYLIB_PREFIX | RUBYLIB for modifying the search path, by using the format path1; path2 or path1path2, the library was replaced prefix path1 path2. |
| RUBYOPT | Ruby interpreter pass command-line options. When taint mode is ignored (wherein, $ SAFE greater than 0). |
| RUBYPATH | After specifying the -S option, search path for Ruby programs. Higher priority than the PATH. When taint mode is ignored (wherein, $ SAFE greater than 0). |
| RUBYSHELL | Specifies the shell command execution when used. If the environment variable is not set, the SHELL or COMSPEC. |
For Unix, use the env command to see a list of all environment variables.
