The cat command has been eliminated. It seems that I really need to learn Linux again.

Overview

In Linux systems, viewing the contents of files is a task that is involved every day. Although the cat command is a commonly used file viewing tool, it has some limitations, such as the inability to perform syntax highlighting or page turning output. The bat command is an enhanced version of the cat command, designed to provide more functions and improve user experience. This article will introduce the characteristics, functions and usage of the bat command in detail, allowing users to manage file content more efficiently.

The bat command is a powerful command line tool used to view file contents. It provides a user-friendly interface and rich features such as syntax highlighting, automatic page turning, and Git integration. Using the bat command, users can more easily view the file contents and perform necessary operations.

Function

1. Syntax highlighting:

The

bat command supports highlighting text keywords based on programming languages ​​​​and markdown syntax, thereby significantly improving the readability of code files and making the code clearer and easier to understand.

2. Automatic page turning:

The bat command will transfer long text to the less command through a pipeline to enable paged browsing and facilitate viewing of large files.

3. Integrate Git:

The bat command is combined with git to display the text modification part on the left side, making it easy to view file changes and improve version control efficiency.

4. Display unprintable characters:

Using the -A or -show-all parameter of the bat command can help display special characters that cannot be displayed by the cat command, which is helpful for viewing files containing special characters.

usage

To use the bat command, just enter the "bat" command in the terminal and add the corresponding options and parameters. Here are a few common usage examples:

1. Basic usage:

The bat command is similar to cat. In addition to displaying text content, it can also display row numbers, file names, table borders and other elements. Example: Use the bat command to view the file named filename.

bat filename

2. Syntax highlighting:

bat provides syntax highlighting for most programming languages ​​and markup languages, making it more readable. For example, to highlight a file named filename in Python syntax, you would use the following command:

bat --language=python filename

3.Git integration:

bat can obtain file modifications from git and display them in the sidebar. For example, to view the Git modifications of a file named filename, you can use the following command:

bat --git filename

4. Display unprintable characters:

Sometimes there are some undisplayable characters in the text. If you use the cat command to view them, you will not be able to see these characters. But if you use the bat command and add the -A or -show-all parameter, you can see it. For example, to view all characters of a file named filename, including non-printable characters, you can use the following command:

bat -A filename
