How do I compare two folders in diff?

Diff has an option -r which is meant to do just that. diff can not only compare two files, it can, by using the -r option, walk entire directory trees, recursively checking differences between subdirectories and files that occur at comparable points in each tree.

Can you diff binary files?

You can force diff to consider all files to be text files, and compare them line by line, by using the –text ( -a ) option. In operating systems that distinguish between text and binary files, diff normally reads and writes all data as text. Use the –binary option to force diff to read and write binary data instead.

When does diff consider a file a binary file?

How to compare binary files to check if they are the same?

You can use MD5 hash function to check if two files are the same, with this you can not see the differences in a low level, but is a quick way to compare two files. If both MD5 hashes (the command output) are the same, then, the two files are not different. Use cmp command. Refer to Binary Files and Forcing Text Comparisons for more information.

Which is the command to compare two files?
