When working with files on Linux or other systems, it’s important to know if a file is human-readable or machine-readable. Human-readable files can be easily opened and understood by a person, while machine-readable files are designed for computers to process. This guide will explain how to tell if a file is human-readable using Linux commands and common file formats.
What Is a Human-Readable File?
A human-readable file contains information that can be easily understood by a person. These files are usually in plain text and can be opened in simple text editors like Notepad or Linux’s nano. Common human-readable files include .txt, .csv, and .json. These files are designed to be accessible without special programs, allowing users to quickly understand the content.
For example, a .txt file may have a to-do list, and a .csv file could contain spreadsheet data. In contrast, files like .bin or .exe are machine-readable, filled with code or data meant for computers, not humans.

How to Tell If a File Is Human-Readable?
To determine whether a file is human-readable, you need to check if its contents can be interpreted by a person without special software. A human-readable file usually contains plain text, numbers, or symbols that are easy to understand. The quickest way to check if a file is human-readable in Linux is to open it with basic commands that display its content.
How to Find Human-Readable Files in Linux
Linux provides various commands to check if a file is human-readable. You can use these tools to open or inspect a file’s contents and determine whether the file can be easily understood.
1. Using the cat Command
The cat command shows the contents of a file in the terminal. It’s a quick way to check if a file is human-readable.
cat filename.txt
If the content is plain and easy to understand, the file is human-readable. If it’s garbled, it’s probably machine-readable.
2. Using the less or more Commands
For larger files, the less and more commands allow you to scroll through the content one page at a time. This is useful when checking log files or long documents to see if they are human-readable.
less filename.txt
or
more filename.txt
3. Using the file Command
The file command provides a description of a file’s contents. It can tell you if a file is human-readable or if it’s a machine-readable format, like binary.
file filename.txt
4. Using head and tail Commands
If you only want to see the beginning or end of a file to check if it’s readable, use the head or tail commands. These commands let you quickly check small parts of a file.
head filename.txt
or
tail filename.txt
5. Using grep to Find Human-Readable Text
The grep command searches a file for specific words or patterns. This is helpful if you are searching for human-readable strings in a file that might otherwise be difficult to read.
grep ‘your_search_term’ filename.txt
This command can quickly find text inside larger files, helping you determine whether the file is readable.
Want to check if your file or text is easy to read for humans? Try the Readability Test Tool from Effeect. It helps you measure how easy or difficult it is to read text, ensuring that your content is accessible and understandable to everyone.
How to Check for a Human-Readable File in the Inhere Directory
Sometimes, you need to check many files at once. You can use the file command to inspect multiple files, such as those in the inhere directory, and find out which one is a human-readable file in the inhere directory.
file inhere/*
This will show details about each file, letting you know which ones are human-readable.
Why Some Linux Commands Have a “Human-Readable” Option
Certain Linux commands, like ls and df, display information in a way that is hard to understand, often using raw numbers like bytes. Using the -h option (short for “human-readable”) converts these numbers into more understandable units, like kilobytes (KB), megabytes (MB), or gigabytes (GB).
ls -lh
This makes the output easier to read, especially when looking at file sizes or disk usage.
Are Text Files Human-Readable?
Most text files are human-readable. They contain plain text or symbols that are easy to understand. Files with extensions like .txt, .csv, and .md can be opened in text editors, where their contents will be readable. However, some text files, like system logs or configurations, may contain technical data that requires special knowledge to interpret, but they are still in a human-readable format.

Conclusion
Understanding whether a file is human-readable or machine-readable is essential for effectively working with different types of files in Linux. By using commands like cat, less, file, and grep, you can easily determine if a file’s contents can be interpreted by a person. Human-readable files contain plain text that is easy to understand, whereas machine-readable files are designed for computers to process. Additionally, tools like Effeect’s Readability Test Tool can help ensure that your text is accessible and easy to read, making it a valuable resource for improving content readability.
