cat is the abbreviation for 'concatenate' and will do binary files just fine. cp will complain if it's instructed to copy multiple source files and the target is not a directory. Windows 'copy' is different from both.	[reply]

Well I guess.. `cp [option]... [-T] source destination` [download] Where -T means: Treat destination as a normal file. I don't work much with Unix nowadays.	[reply] [d/l]

That's version dependent. But, anyway, worthy to be added to my TIL list.	[reply]

copy (cp) works with binary files. type or cat is designed to work with text files. Note that on NIX/POSIX, there is generally no distinction between "binary" and "text" files. `cp` doesn't concatenate multiple files (`-T`, from your reply below, makes no difference here) - `cat` is "the" NIX tool for concatenating files. If I guess that by "binary" vs. "text" you maybe mean "block-by-block" instead of "line-by-line", then that is course a valid point in regards to performance. But at least GNU Coreutils' `cat` is optimized to read and write files block-by-block, not line-by-line, when it doesn't need to do any line-by-line processing - see its `simple_cat` function.

On Windows, I believe the equivalent to your Unix command would be: `type *.log > result` [download] No, it is not. `type` treats Ctrl-Z (ASCII 26) as end-of-file marker. cat writes its entire input to STDOUT. `cat` can handle binary files, `type` can't.
