Using vimdiff on Linux: Compare Files with Visual Highlighting in Vim
A little-known tool for programmers that can greatly help find problems in code is the vimdiff command in Linux.
This tool allows you to open two source code files at the same time and makes comparisons, indicating which line and what is different between the files.
This is very useful to check differences between development code and one in production, especially in interpreted languages, JSON, XML files, etc.
To use vimdiff, the command is simple: just specify which two files are to be compared:
$ vimdiff arquivo1.php arquivo2.phpThe result is a screen with two windows, and with highlighting of the different lines:

After years of watching professionals waste hours on simple tasks because they didn't know the right Linux tools, I decided to teach.
Today I'm the author of most of LPI's official Learning Materials and mentor to over 14,000 certified students.
That was just one piece. The course teaches the whole path — from your first command to exam day.
