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

First I created each file: echo 'information' > file1.txt for each file[123].txt.

Then I printed each file to makes sure information was correct: tail file?.txt

Then I did this: tail file?.txt >> Mainfile.txt. This created the Mainfile.txt to store the information in each file into a main file.

cat Mainfile.txt confirmed it was okay.

==> file1.txt <== bluemoongoodbeer

==> file2.txt <== awesomepossum

==> file3.txt <== hownowbrowncow

Answer 2

find . -type f -exec cat {} \; -print
