cmp Command

The cmp command is a command-line utility on Linux and other Unix-like operating systems that is used to compare the contents of two files. It returns an exit status of 0 if the files are identical, and a non-zero exit status if the files are different. Here are a few examples of how to use the cmp command:

To compare the contents of two files, you can use the following syntax:

$ cmp file1 file2

You can also compare the contents of two files and display the offset of the first byte that differs by using the -l option:

$ cmp -l file1 file2

You can compare two files while ignoring the end of line (EOL) differences by using the -s option:

$ cmp -s file1 file2

To compare the content of two file byte by byte you can use option -b

$ cmp -b file1 file2

To compare two binary files and print the hexadecimal values of all differing bytes you can use option -x

$ cmp -x file1 file2

cmp command is a good way to compare contents of two files and check if they are identical or not and also with the options it provides flexibility to check byte by byte comparision or check EOL differences.
