Detects if a file is binary in Node.js. Similar to Perl's -B.

nullbyte; if it's found, it's binary
All the logic is also pretty much ported from ag.
Note: if the file doesn't exist or it is empty, this function returns
npm install isbinaryfile
If you pass in one argument, this module assumes it's just the file path, and performs the appropriate file read and stat functionality internally, as sync options:
var isBinaryFile = require"isbinaryfile";if isBinaryFileprocessargv2console.log"It is!"elseconsole.log"No."
However, if you've already read and
stat()-ed a file (for some other reason),
you can pass in both the file's raw data and the stat's
size info to save
fsreadFileprocessargv2fslstatprocessargv2if isBinaryFiledata statsizeconsole.log"It is!"elseconsole.log"No.";;
Previous to version 2.0.0, this program always ran in sync mode. Now, there's
an async option. Simply pass a function as your second parameter, and
will figure the rest out:
var isBinaryFile = require"isbinaryfile";isBinaryFileprocessargv2if err return console.errorerr;if resultconsole.log"It is!"elseconsole.log"No."
Install mocha on your machine:
npm install mocha -g
