Quoting the output of a backtick command

Question

I'm trying to run an expect script that runs a telnet session to automate the sending of an email, I'm trying to pass the contents of a file as a single argument to my script but when the backticks are interpreted the white space in that file are causing multiple arguments to be passed.

Here's my command...

runTelnet `cat test_results.txt`

Is there a way to quote the output of a backtick expression?

Try:

runTelnet "$(cat test_results.txt)"

Use:

runTelnet "`cat test_results.txt`"

Enclosing the backticks in quotes will cause the results of the command to be passed to runTelnet as a single argument.
