Conclusion

File extensions are not always used completely or consistently. What if a file does not have an extension or does not match the extension? In this case, the file command will be helpful. For example, if you find a file named ins in the/root directory without an extension, you can use the file command to determine the file type, for example:

# File/root/ins

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