Package Exports

which

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (which) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

which

Like the unix which utility.

Finds the first instance of a specified executable in the PATH environment variable. Does not cache the results, so hash -r is not needed when the PATH changes.

USAGE

var which = require('which')

// async usage
which('node', function (er, resolvedPath) {
  // er is returned if no "node" is found on the PATH
  // if it is found, then the absolute path to the exec is returned
})

// sync usage
// throws if not found
var resolved = which.sync('node')

// Pass options to override the PATH and PATHEXT environment vars.
which('node', { path: someOtherPath }, function (er, resolved) {
  if (er)
    throw er
  console.log('found at %j', resolved)
})

OPTIONS

If you pass in options, then path and pathExt are relevant.
