Not clear on what the OP wants, so no comment here.

A here document is a shell construct by which you can simulate
redirection from a file on the command-line. For instance, if you
wanted to copy the following text to a floppy:
This is the house that Jack built.
This is the malt that lay in the house that Jack built.
you can put it into a file, say /tmp/file.txt, then:
cat < /tmp/file.txt > /dev/fd0
If you want to avoid the intermediate step of creating file.txt, you can
use a here document with the content you want:
cat > /dev/fd0 <<some_string
This is the house that Jack built.
This is the malt that lay in the house that Jack built.
some_string
The effect is as if you had put the text between
some_string...some_string in a file and redirected stdin from that file,
except that no actual file is created. Convenient for quick-and-dirty
texts, specially stuff you copy-paste from some application.
