Compare or have a diff between 2 files with ease

Beyond Compare 3 is the ideal tool for comparing files and folders on your Windows or Linux system. Visualize changes in your code and carefully reconcile them.

Beyond Compare’s new merge view allows you to combine changes from two versions of a file into a single output.  Its intelligent approach allows you to quickly accept most changes while carefully examining conflicts.  Color coding and section highlighting allow you to accept, reject, or combine changes, simply and easily.  And, you can change any line in the output with the built-in syntax-highlighting editor.  By using Beyond Compare’s powerful file type support and ability to favor changes from one file, you can trivially accept many changes without even seeing them.

You can use Beyond Compare directly from most version control systems, giving you all of the powerful comparing and merging support you need when you need it most.  Integrated source control commands are also available, allowing you to check in and check out files without interrupting your work.
