# osenv Look up environment settings specific to different operating systems. ## Usage ```javascript var osenv = require('osenv') var path = osenv.path() var user = osenv.user() // etc. // Some things are not reliably in the env, and have a fallback command: var h = osenv.hostname(function (er, hostname) { h = hostname }) // This will still cause it to be memoized, so calling osenv.hostname() // is now an immediate operation. // You can always send a cb, which will get called in the nextTick // if it's been memoized, or wait for the fallback data if it wasn't // found in the environment. osenv.hostname(function (er, hostname) { if (er) console.error('error looking up hostname') else console.log('this machine calls itself %s', hostname) }) ``` ## osenv.hostname() The machine name. Calls `hostname` if not found. ## osenv.user() The currently logged-in user. Calls `whoami` if not found. ## osenv.prompt() Either PS1 on unix, or PROMPT on Windows. ## osenv.tmpdir() The place where temporary files should be created. ## osenv.home() No place like it. ## osenv.path() An array of the places that the operating system will search for executables. ## osenv.editor() Return the executable name of the editor program. This uses the EDITOR and VISUAL environment variables, and falls back to `vi` on Unix, or `notepad.exe` on Windows. ## osenv.shell() The SHELL on Unix, which Windows calls the ComSpec. Defaults to 'bash' or 'cmd'.
