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


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.


```javascript 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) }) ```


Same as the BSD which(1) binary.

usage: which [-as] program ...


You may pass an options object as the second argument.
