A member file download can also be achieved by clicking within a package contents listing on the according byte size field.

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)
})

CLI USAGE

Same as the BSD which(1) binary.

usage: which [-as] program ...

OPTIONS

You may pass an options object as the second argument.
