How to Check the File Type in Unix System?

What command is used to determine the file type in Unix-like operating systems?

a) type

b) check

c) file

d) format

Final answer:

The correct command used to determine the file type in Unix-like operating systems is 'file'.

The 'file' command in Unix is a powerful tool that allows users to determine the type of a file at a specified path. By using the syntax 'file /path/to/file', you can quickly identify whether the file is a binary executable, a text file, or any other type of file.

For example, if you run 'file /usr/bin/clean-binary-files' and the command returns 'ELF 64-bit LSB shared object', it indicates that the file is a binary executable. On the other hand, if it returns 'ASCII text', it means that the file is a text file.

The 'file' command provides valuable information for understanding the nature of a file without needing to open it directly. This can be particularly useful for system administrators and developers who need to work with various file types in a Unix environment.
