Can cat combine binary files?

Yes, the cat command can combine binary files as well as text files. You can use it in the same way as you would for text files. For example:

cat binaryfile1.bin binaryfile2.bin > combined_binary.bin

This command will concatenate binaryfile1.bin and binaryfile2.bin into a new file called combined_binary.bin.

However, keep in mind that when working with binary files, the output may not be human-readable, and you should ensure that the resulting combined file is used in a context that supports binary data.
