Concatenate multiple files but include filename as section headers

Question

I would like to concatenate a number of text files into one large file in terminal. I know I can do this using the cat command. However, I would like the filename of each fi

Answer 1

find . -type f -print0 | xargs -0 -I % sh -c 'echo %; cat %'

This will print the full filename (including path), then the contents of the file. It is also very flexible, as you can use -name "expr" for the find command, and run as many commands as you like on the files.
