For using cat to output *.txt files within a specific directory, how can I insert the filename as a "break" before each file?
file #1
contents of file
file #2
contents of file
ideally as an easy to remember few bash commands.

1Please clarify the question, what do you mean by 'insert the filename as a 'break' ? – 0stone0 Dec 09 '20 at 13:40

I just mean print the file name somehow, as `ls foo` would result in. along those lines. – Thufir Dec 09 '20 at 14:11

Improved answer;
Instead of an separate -exec basename, using just -print will show the filename:
find . -type f -print -exec cat {} \;
You could use a find command with multiple -exec;
find . -type f -iname '*.txt' -exec basename {} \; -exec cat {} \;
-> ls
a.txt b.txt
-> find . -type f -iname '*.txt' -exec basename {} \; -exec cat {} \;
b.txt
b
a.txt
a

2`find` is quite useful for other reasons, getting familiar with the syntax could be quite useful. – 0stone0 Dec 09 '20 at 14:17

One more option to @0stone0 answer
You can use tail insted of cat:
tail -n +1 *
Output:
==> file-1.txt <==
contents of file
==> file-2.txt <==
contents of file

excellent. can I use `cat` or `nl` rather than tail? or, I suppose it's probably possible to just `tail` an entire file. – Thufir Dec 09 '20 at 14:13

if you want to search a string in list of files then this should be best option. This will print the filenames as well
grep "some string" *.log
