In the world of Linux, there are many different file encodings available, and sometimes it’s necessary to determine which one is being used. In this article, we’ll explore how to check the encoding of a file in Ubuntu, using various methods and tools.
To check the encoding of a file in Ubuntu, you can use the
file command, which provides information about the file’s type and encoding. Additionally, you can use a Python script that scans the file and attempts to decode it using different character sets. Another option is to use the
detect-file-encoding-and-language package, which provides a more comprehensive solution.
Understanding File Encoding
File encoding is a form of assigning binary codes to characters, numbers, and symbols. It ensures that files and data can be read and understood by different systems and applications. Common file encodings include ASCII, UTF-8, and ISO-8859-1.
Method 1: Using the
The simplest way to check the encoding of a file in Ubuntu is by using the
file command. This command-line tool provides information about a file’s type and encoding.
Here’s how to use it:
FILENAME with the name of your file. The command will output the file type and its encoding.
This might output:
example.txt: ASCII text
In this case, the encoding of the file is ASCII.
Method 2: Using a Python Script
If you’re comfortable with Python, you can use a script to scan the file and attempt to decode it using different character sets.
Here’s an example of such a script:
r_file = open(fname, 'rb').read()
result = chardet.detect(r_file)
charenc = result['encoding']
your_file = input('Enter your file name: ')
In this script,
chardet.detect() returns a dictionary with information about the encoding. The ‘encoding’ key provides the name of the encoding used in the file.
Method 3: Using the
For a more comprehensive solution, consider using the
detect-file-encoding-and-language package. This package requires Node.js and NPM (Node Package Manager) to be installed on your system.
First, install the package with:
npm install -g detect-file-encoding-and-language
Then, use the
dfeal command to detect the encoding of a specific file:
This command will output the probable encoding and language of the file.
Determining the encoding of a file in Ubuntu can be achieved through various methods, from simple command-line tools like
file, to Python scripts, to dedicated packages like
Remember, converting a file to a different encoding may result in data loss or corruption if the original encoding is not accurately determined. Therefore, always ensure you have a backup of your files before attempting any conversion.
In the Linux world, understanding file encoding is crucial. It not only helps in data interpretation but also aids in data integrity during file conversions. By following the steps outlined in this guide, you should be able to easily determine the encoding of a file in Ubuntu.

Some common file encodings include ASCII, UTF-8, and ISO-8859-1.
There are multiple methods to check the encoding of a file in Ubuntu. You can use the
file command in the terminal, write a Python script using the
chardet library, or use the
To use the
file command, open the terminal and enter
file FILENAME, replacing
FILENAME with the actual name of your file. The command will output the file type and its encoding.
Yes, you can use a Python script. The example script provided in the article uses the
chardet library to scan the file and detect its encoding.
detect-file-encoding-and-language is a package that can detect the encoding and language of a file. It requires Node.js and NPM to be installed on your system.
To install the package, open the terminal and enter
npm install -g detect-file-encoding-and-language. This will install the package globally on your system.
Yes, file encoding can be converted to a different encoding. However, it is important to accurately determine the original encoding before attempting any conversion to avoid data loss or corruption.
