Diffchecker for the Terminal
Now you can create cloud-hosted diffs right from the command line. Easily compare 2 files, or compare a current file with the version of itself from the most recent commit.
Why use this instead of a native app? Because your diffs are instantly uploaded so you can share them with others.
Installation
First, make sure you have Node with npm installed from nodejs.org
Then:
npm install -g diffchecker
Usage
To compare two files:
diffchecker file1.js file2.js
To compare a file with it's version from the most recent git commit:
diffchecker file1.js
Both methods will open the diff in your default browser.
By default, the diff will expire in 1 hour. You can change it to 1 day, 1 month or forever like this:
diffchecker --expires day file1.js file2.js
Should you want to sign out:
diffchecker --signout
