How can I suppress parameter expansion in a here-doc in Bash?

Question

I'd like to do the following in bash, but without having variables interpolated:

cat >aBashScript.sh <<EOL
$name
EOL

The file should contain $name, but instead it's empty. How does one do that?

Answer 1

You can disable parameter expansion in here documents by quoting the limit string:

cat >aBashScript.sh <<'EOL'
$name
EOL

Answer 2

You need to escape the dollar sign, simply prefix it with a backslash to escape it like so:

cat >aBashScript.sh <<EOL
\$name
EOL

Or disable quoting as @Michael suggested.
