Whereas writing program recordsdata or regular textual content recordsdata, programmers and writers generally wish to know the distinction between two recordsdata or two variations of the identical file.
Whenever you evaluate two pc recordsdata on Linux, the distinction between their contents is known as a diff. This description was born out of a reference to the output of diff, the well-known Unix command-line file comparability utility.
There are a number of file comparability instruments that you need to use on Linux, and on this evaluate, we will have a look at a number of the finest terminal-based and GUI diff instruments you’ll be able to make the most of whereas writing code or different textual content recordsdata.
1. diff Command
I like to begin with the unique Unix command-line software that reveals you the distinction between two pc recordsdata. Diff is straightforward and simple to make use of, it comes pre-installed on most Linux distributions, which compares recordsdata line by line and outputs the distinction between them.
To match two recordsdata and show the variations.
$ diff file1.txt file2.txt
You’ll be able to take a look at the handbook entry for diff to simply use it.
# man diff
There are some wrappers for the diff software that improve its performance and these embody:
colordiff Command

To match two recordsdata utilizing vimdiff, you’ll execute the next command.
$ vimdiff file1.txt file2.txt
You can too use vimdiff to match three recordsdata.
$ vimdiff file1.txt file2.txt file3.txt
For extra detailed data and utilization choices, you’ll be able to entry the handbook web page by operating.
$ man vimdiff
3. sdiff
The sdiff command is used to match two recordsdata facet by facet, highlighting the variations between them. It shows the contents of the 2 recordsdata in separate columns, with added traces prefixed by ">", deleted traces prefixed by "<", and customary traces displayed with none prefixes.
The sdiff command usually comes with the usual set up of most Linux distributions. Nevertheless, if it’s not put in, you’ll be able to set up it utilizing your bundle supervisor.
$ sudo apt set up diffutils [On Debian, Ubuntu and Mint] $ sudo yum set up diffutils [On RHEL/CentOS/Fedora and Rocky/AlmaLinux] $ sudo emerge -a sys-apps/diffutils [On Gentoo Linux] $ sudo apk add diffutils [On Alpine Linux] $ sudo pacman -S diffutils [On Arch Linux] $ sudo zypper set up diffutils [On OpenSUSE]
To match two recordsdata and show the variations facet by facet.
$ sdiff file1.txt file2.txt
