What command can be used to show the file type?
To determine the file type in Linux, we can use the file command. This command runs three sets of tests: the filesystem test, magic number test, and language test. The first test that succeeds causes the file type to be printed. For example, if a file is a text file, it will be recognized as ASCII text.

What does the diff command do in Linux?
On Unix-like operating systems, the diff command analyzes two files and prints the lines that are different.

The diff software does not actually change the files it compares.
How can I check if a file is the same as diff?
There are a couple of simple ways to check whether or not files are identical. If you use -s it will tell you the files are identical or it will run diff as normal. Using -q will only tell you that the files “differ”. If they do not, you will get no output. You might not always be comparing such simple information.
