Question: I want to use a command to be printed on the same line as the string.
for example, i want to print something like:

hostname: cpu1

but when i use the command like this it doesnt work

```
echo 'hostname:' hostname

```

Answer: 
You need to use `$()` to evaluate:
echo 'hostname:' $(hostname)
This is what you should do:

```
echo "hostname: `hostname`"

```

Words enclosed in backticks are read by the command line as commands even when they are inside a string, like in this case.

Have a great day! :)
