Create a filesuggest change
A classic use of here documents is to create a file by typing its content:
cat > fruits.txt << EOF apple orange lemon EOF
The here-document is the lines between the
<< EOF and
This here document becomes the input of the
cat command. The
cat command simply outputs its input, and using the output redirection operator
\> we redirect to a file
As a result, the
fruits.txt file will contain the lines:
apple orange lemon
The usual rules of output redirection apply: if
fruits.txt did not exist before, it will be created. If it existed before, it will be truncated.
