As a Linux user, it is important to be able to determine the file type of the files you are working with. While the easiest way to determine file type is by looking at the file extension, Linux terminal commands offer more options. In this post, we will cover some of the best ways to determine file type in linux using terminal commands.

Using the file command

The “file” command is the simplest way to determine file type in Linux. It runs three tests to determine file type: filesystem test, magic number test, and language test. To use the “file” command, simply type “file” followed by the file name.

For example, to determine the file type of a file named “example.docx” located in the current directory, type:

The output will show the human-readable file type or MIME type. For example, the output for the “example.docx” file may be:

example.docx: Microsoft Word 2007+ 

Listing all files and their file types

To list all files and their file types in the current directory, use the command “file ./*”. This command will show the file type for each file listed in the directory.

For example, to list all files and their file types in the current directory, type:

The output will show the file type for each file listed in the directory.

Other commands to determine file type

There are other commands that can be used to determine file type in Linux. One such command is “stat -c ‘%F’ filename”. This command can be used to determine file type.

For example, to determine the file type of a file named “example.docx” located in the current directory, type:

The output will show the file type. For example, the output for the “example.docx” file may be:

The “ls -l” command can also show file type using the -l or -F options. To show file type using the -l option, type:

The output will show the file type along with other file information. For example, the output for the “example.docx” file may be:

-rw-r--r-- 1 user user 1024 Sep 1 12:30 example.docx 

Checking file type using Properties option

The file type of a document can be checked using the Properties option after right-clicking on the file. This option will show the file type under the General tab.

Finding files with specific extensions using the find command

The find command can be used to search for files with specific extensions . For example, typing “find . -name ‘*.txt’” will find all files with a .txt extension in the current directory.

For example, to find all files with a .docx extension in the current directory and its subdirectories, type:

The output will show the file paths for each file found.

Other code examples for determining file type in Linux via terminal commands include «file -i filename» and «xdg-mime query filetype filename»

Conclusion

determining file type in linux is important for opening files correctly and ensuring compatibility with other programs. The “file” command is the simplest and most reliable way to determine file type in Linux. Other commands such as “ls -l” and “stat” can also be used to determine file type. Using the Properties option and the find command are additional options for checking file type in Linux. By using these commands, you can easily determine the file type of any file in Linux.

Linux is an open-source operating system that is widely used for its flexibility and customization options. One of the crucial tasks when working with files in Linux is checking their type, which can be done using various commands and tools. In this blog post, we will explore different methods to check any file type in Linux, ranging from using the file command to writing scripts in bash.

Checking file type by extension

The simplest way to determine a file’s type in Linux is to look at its extension. For instance, files with .txt extension are text files, while those with .jpg extension are image files. However, this method is not always accurate, as file names in Linux can be independent of file types, making it tricky to determine the actual information. Therefore, it is important to use other methods to ensure accuracy.

Using the file command

The file command is a Linux utility that can be used to determine the type of a file by analyzing its contents. The file command runs three sets of tests: filesystem test, magic number test, and language test. The filesystem test checks the file’s metadata, while the magic number test looks for specific file signatures. The language test tries to identify the programming language used to create the file.

The file command can be used with various options, such as -i to display MIME type, -b to display only the file type, and -z to suppress warning messages. For example, to check the type of a file named “example.txt”, simply run:

This will display the file type, such as “ASCII text” or “JPEG image data”.

Checking file type with ls command

The ls command is another useful utility in Linux that can also show the file type as an encoded symbol in the first character of the file-system permissions field. The file type symbol can be decoded using the following table:

Symbol	File Type
—	Regular file
d	Directory
l	Symbolic link
c	Character device file
b	Block device file
s	Socket
p	Named pipe

For example, to list all files in the current directory with their file types, run:

This will display the file type symbol, followed by other file information, such as ownership and permissions.

Finding files with specific extension using find command

The find command is a powerful tool in Linux that can be used to search for files based on various criteria , including file type. To find all files with a specific extension, the find command can be used with the -name option, followed by the file extension. For example, to find all text files in the current directory and its subdirectories, run:

This will display the path of all text files found in the current directory and its subdirectories.

Checking file status with stat command

The stat command is another helpful utility in Linux that can be used to check the status of a file, including its type. The stat command displays various information about a file, such as its size, permissions, and type. For example, to display the status of a file named “example.txt”, run:

This will display the file status, including its type, such as “regular file”.

Searching for specific text within files using grep command

The grep command is a versatile tool in Linux that can be used to search for specific text within files. This method can be useful when trying to find files that contain specific keywords or phrases. For example, to search for the word “example” in all text files in the current directory and its subdirectories, run:

This will display the path of all text files that contain the word “example”.

Checking file type in bash script

To check the file type in bash, a script can be written using the -e, -f, and -d flags. The -e flag checks if the file exists, while the -f flag checks if the file is a regular file. The -d flag checks if the file is a directory. For example, to check if a file named “example.txt” is a regular file, run:

if [ -f example.txt ]; then echo "example.txt is a regular file" fi 

This will display “example.txt is a regular file” if the file exists and is a regular file.

Conclusion

Checking the file type is a crucial task when working with files in Linux. While the extension method is the simplest, it is not always accurate. The file command is a powerful tool that can analyze a file’s contents to determine its type. The ls command, find command, stat command, grep command, and bash scripts are also useful methods to check file types in Linux. By using multiple methods and tools, one can ensure accuracy and compatibility with the latest file types.
