Bash: How to put hostname between quotes in file

Question

I try to add the hostname of my server in a file but it fails. I tried:

HOST=`hostname`
echo ' "server": "${HOST}"' >> /myfile

And I tried:

echo ' "server": "`hostname`"' >> /myfile

It's important to know that I need this output in my file:

"server": "ip-133..."

Answer 1

Try this:

$ echo "\"server\": \"$(hostname)\"" >> myfile
