How can I copy several binary files into one file on a Linux system?

I need to copy the content of a folder which contains binary files to one binary file in another directory.

In Windows I can just use:

copy file1 + file2 targetfile /B 

I couldn't find something similar for Linux (I saw an approach with cat, but I'm unsure if this really works for binary files).

Unix has no distinction between text and binary files, which is why you can just cat them together:

cat file1 file2 > target_file 

cat is a very useful utility that will output the content of one or more files to standard output. That can be redirected with shell-funcionality into a file. It will work with binary or ascii files. In some programming languages that do not use linking, cat is used to merge binary files into a single executable file.

cat file1 file2 > target_file
