Concatenating multiple text files into a single file in Bash

cat multiple files and subshell

Since you only have a single subshell I'd use this :

markdown page.md | cat header - footer > page.html

The - in the cat params refers to stdin, which is populated by the markdown command.

If you had multiple subshells, I'd recommend using the solution anishane commented about, process substitution :

cat header <(markdown page1.md) <(markdwon page2.md) footer > page.html
