Combine files from terminal I created two files

$ 'test' &gt; test.md
$ 'hello' &gt; hello.md


try to combine them

cat test.md hello.md &gt; combined.md


Unfortunately, the newly combined.md is blank.

How to combine files from terminal with commands?
You need to 'echo` your words into the files.

echo test &gt;test.md
echo hello &gt;hello.md
cat test.md hello.md &gt;combined.md
