This is going to be VERY fragile, but does work for simple yaml. Overall it is last resort, but can get you out of a jam.

<pre>
{
printf 'host_entries:\n'
while read -r -a line; do
[[ ${line[0]} ]] || continue # skip blank lines
[[ ${line[0]} = "#"* ]] && continue # skip comments
[[ ${line[0]} = 127.0.0.1 ]] && continue # skip localhost

set -- "${line[@]}" # assign words read from line to current argument list
ip=$1; shift # assign first word from line to ip
for name; do # iterate over other words, treating them as names
printf " %s:\n ip: '%s'\n" "$name" "$ip"
done
done
} </etc/hosts >yourfile.yaml

This is WRONG but works for this simple case. Creating a YML file from a vars file should be less problematic however since it is key=value

This will allow creating a YML file with bash substitutions.
example is for bosh!!
