Bash shell script to echo hostname and kernel version

Question

     `hn = 'hostname'
      echo "Hostname: $hn"`

This is what I did for the kernel version as well, but this is giving me a two line output with the hostname on top and then "Hostname:" below. So how do I get the output to be "Hostname: " ?

hn=$(hostname) bash does NOT allow spaces around '=' You can just echo "Hostname: $(hostname)" — David C. Rankin

$(hn=`hostname`; echo "Hostname: $hn")

or a more human readable format:

$(hn=$(hostname); echo "Hostname: $hn")

Good job for pointing out the preferred readability of command substitution with $(...) rather than backticks, `...`.
