Mastering File Types on Linux with the File Command

Have you ever come across a file on your Linux system and wondered what type of file it is? The Linux file command is a handy tool that can help you determine the type of file you’re dealing with.

In this article, we will explore how to use the Linux file command to find file types. We will cover syntax and usage, simple use cases, the use of the -b option, finding the type of multiple files, using wildcard characters, and viewing the MIME type.

Using the Linux file Command

The Linux file command is used to determine the type of a file. It examines the content of a file and provides detailed information on its format.

The syntax for using the file command is straightforward:

file [option] [file name]

The type of file that the command returns depends on the option used. For example, to determine whether a file is an ASCII text file, the command is:

file filename.txt

This command will return “ASCII text” if the file is in ASCII text format.

Simple Use Case

One of the most common uses of the Linux file command is to determine whether a file is in ASCII text format. This is particularly useful if you are dealing with a text file that you need to edit or read.

To determine whether a file is in ASCII text format, use the command:

file textfile.txt

This will return “ASCII text” if the file is in ASCII text format.

Using the -b Option

If you want a brief output from the Linux file command, you can use the -b option. This will give you a more concise output that is easier to read.

For example:

file -b textfile.txt

This will return “ASCII text” in a more brief format.

Finding the Type of Multiple Files

If you need to check the file type of multiple files, you can use a combination of the Linux file command and the xargs command. The xargs command reads items from standard input and executes the command for each item.

To check the file type of multiple files, the command is:

echo file1.txt file2.jpg file3.pdf | xargs file

This command will return the file type for each file in the list.

Using Wildcard Characters

The Linux file command can also be used with wildcard characters such as * or ?. This is useful if you need to check the file type of a group of files that have similar names.

For example:

file *.txt

This command will return the file type of all files with a .txt extension in the current directory.

Viewing the MIME Type

The Linux file command can also be used to determine the MIME (Multipurpose Internet Mail Extensions) type of a file. The MIME type is a standardized way of identifying the type of content that is being transmitted.

To view the MIME type of a file, the command is:

file -i filename.txt

This command will return the MIME type of the file in question.

Recap of the Linux File Command Usage

In conclusion, the Linux file command is a valuable tool that can help you determine the type of file you are dealing with. With the syntax and usage, simple use case, use of the -b option, finding the type of multiple files, using wildcard characters, and viewing the MIME type, you can easily determine the type of file you are working with.
