File comparison

File comparison

●Compare two files

To see if there is a difference between the two files, use the “cmp” command.
Specify the file you want to compare as an argument and run it.
If there is a difference, it will print the byte position and line number. Also, if there is no difference, the cmp command will not display any message, only a prompt.
