This a simple CLI tool to compare two files and show the differences. It is written in Rust.

The tool is inspired by the diff command and git changes visualization, but it is simpler and easier to use. Always, the first file is the reference, and the second file is the one to compare.


From crates.io

To install the tool, you need to have Rust installed. Then, you can run the following command:

cargo install compare-files

From source

or you can clone the repository:

git clone https://github.com/rohaquinlop/rust-compare-files.git
cd rust-compare-files
cargo install --path .


To compare two files, you can run the following command:

compare-files /path/to/file1 /path/to/file2

The output will show the differences between the two files. For example, if the files are:


The output will be:

1: 1
2: - 2
3: 3
3: + 4

The files you provided are differents!

Here is the summary:
+ 1 line added.
- 1 line deleted.

As you can see, the output shows the differences between both files. If you're using an ansi-compatible terminal, you can see the output with colors.

Let's say you have two files, file1.txt and file2.txt, and you want to compare them. You can run the following command:

compare-files file1.txt file2.txt

Even, you can compare them if they are in different directories:

compare-files ~/Documents/file1.txt ./file2.txt
