Conclusion

File extensions are not always won or used consistently. What if a file does not have an extension or does not match its extension? At this point, the file command will help. For example, a file called ins is found in the / root directory, which has no extension. You can use the file command to determine the type of the file, such as:

# file / root/ins

The command format is file + file path + file name.
