What are the tools for analysis in Linux? In response to this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more small partners who want to solve this problem find a simpler and easier way.

1. diff command

diff command is a powerful text comparison tool that comes with Linux and is very easy to use. For its use, I also wrote a separate article before, click on the link below to view.

Teach you a trick under Linux text comparison method

The diff command, which comes pre-installed in most Linux distributions, compares two text files line by line and prints out their differences. More information can be found directly in its man manual.

$ man diff

However, the diff command is powerful, but its output is too touching, not intuitive and not clear. Therefore, in order to make up for this shortcoming, some big shots developed more powerful tools based on diff. Here are two recommendations: colordiff and wdiff.

colordiff command

Colordiff is a Perl scripting tool that produces the same output as diff, but with colored code and syntax highlighting. Also, you can customize the theme if you don't like its default color.

You can install colordiff on your computer by selecting different installation commands depending on the distribution.

$ yum install colordiff [On CentOS/RHEL/Fedora]$ dnf install colordiff [On Fedora 23+ version]$ sudo apt-get install colordiff [On Debian/Ubuntu/Mint]

Similarly, you can use the man command to view its help documentation:

$ man colordiffwdiff command

The diff command compares differences line by line, while wdiff is more perverted and compares word by word. So if your text changes only a few words, it will be more efficient to use wdiff.

The installation commands are as follows:

$ yum install wdiff [On CentOS/RHEL/Fedora]$ dnf install wdiff [On Fedora 23+ version]$ sudo apt-get install wdiff [On Debian/Ubuntu/Mint]

More details can be found in its man manual.

$ man wdiff2. vimdiff command

vimdiff is equivalent to vim -d, the diff mode of the Vim editor.

This command is usually followed by two or more file names, which are simultaneously opened in the split window of the Vim editor and highlight the parts of the file that differ in content.

Its Chinese homepage is vimcdoc.sourceforge.net/doc/diff.html

The above two are Linux command-line comparison tools, let's look at some GUI comparison tools.

3. Kompare

Komhare is a diff-based GUI tool that makes it easy for users to see differences between files and supports merging those differences.

Komhare features are as follows:

Support multiple diff formats; support comparison between directories; support reading diff files; customize interface; create and apply patch files of source files.

The tool's home page is www.kde.org/applications/development/kompare/

4. DiffMerge

DiffMerge is a cross-platform GUI text comparison tool available on Linux, Windows, macOS. We know that BeyondCompare is a paid app, so if your company has high copyright requirements, consider DiffMerge.

DiffMerge has two main functions: 1. Illustrates changes between two files. Includes internal line highlighting and full editing support. 2. Illustrates changes between the three files. Allows automatic merging (when safe to do so) and full editorial control over the resulting file.

It has the following characteristics:

Supports folder comparison; integrated file browser; highly configurable.

The tool's home page is sourcegear.com/diffmerge/

5. Meld

Meld is a lightweight GUI code comparison tool that allows users to compare files, directories, and highly integrated version control software. But for software developers, it has several features that are particularly appealing:

Perform two-way and three-way differencing and merging Easily navigate between differences and conflicts Compare two or three directories file-by-file, show new files, missing files, and changed files Supports many version control systems, including Git, Mercurial, Bazaar, and SVN, among others.

Its official website is meldmerge.org/

6. Diffuse

Diffuse is another popular, free, small, and very simple GUI text comparison and merge tool written in Python with two main functions: file comparison and version control, allowing file editing, merging, and outputting differences between two files.

You can use it to view text comparison summaries and select a line in a file to edit with the mouse. Other features include:

Syntax highlighting shortcuts facilitate text navigation Unlimited Undo Support unicode encoded files support many version control systems, including Git, Mercurial, Bazaar and SVN.

Its official website is diffuse.sourceforge.net/

7. XXdiff

XXdiff is a free, powerful file and folder comparison and merge tool that runs on many Unix-like systems. However, it has a limitation that it does not support unicode files, and there is no way to edit files directly.

It has the following characteristics:

Recursively compare files and folders Highlight differences Merge differences Export results Support external diff tools such as GNU diff, SIG diff, Cleardiff, and many more Support script extensions

8. KDiff3

KDiff3 is another powerful cross-platform difference matching and merging tool developed by KDevelop that runs on all Unix-like platforms, including Linux, Mac OS, Windows, etc.

It can compare or merge two or three files or directories and has the following characteristics:

Can compare differences sentence by sentence, word by word Support automatic merge Built-in editor, Can manually resolve conflicts Support unicode, UTF-8 and other encoding formats Support print differences

Its official website is http://kdiff3.sourceforge.net/

9. TkDiff

TkDiff is another cross-platform, easy-to-use GUI text comparison tool that runs on Linux, Windows and MacOS. It also provides a left-right split interface for viewing two files in contrast.

However, it also has features that other text comparison tools don't, such as difference bookmarks and a navigation map that makes it easy to quickly locate navigation differences.

Its official website is sourceforge.net/projects/tkdiff/

About Linux tools analysis tools have what questions to share here, I hope the above content can have some help for everyone, if you still have a lot of doubts not solved, you can pay attention to the industry information channel to learn more about knowledge.
