Is there a quick way to copy one file's content to another one, without iterating the file line by line and writing to the other file?

This tells `cat` to output the concatenation of files named `readfile.txt`, `>>`, and `writefile.txt`. `cat` doesn't process `>>` the way you're relying on; that's the shell's job. – user2357112 Oct 12 '18 at 22:02
