Is there a bash equivalent to "some content #{foo}" with ruby?

I'm used to being able to pass variables inside strings in ruby, like so

"message in double quotes #{expression_or_variable_to_run}"

What's the equivalent in bash, for really quick scripting?

bash ruby

    Is this what you're after?

    #!/bin/bash

# Source hostname from command.
echo "Hostname is $(hostname)"

# Set hostname as string.
HOSTNAME="somestring"
echo "Hostname is ${HOSTNAME}"

  2. Maybe this will help you understand some basics:

    #!/bin/bash
VARIABLE="is"
echo "the server $VARIABLE `hostname`"

    Variables are defined without $, referenced with $. Shell commands can be executed within `` quotes.
