A Bash web server

Nice oneliners which may be useful to show some console output via HTTP.

An example of showing the iptables FORWARD chain:

while true ; do echo -e "HTTP/1.1 200 OK\n\n $(sudo iptables -L FORWARD -vn --line-numbers)" | nc -l -p 8080 -q 1; done

Then go to http://ip.add.re.ss:8080 and you will see the output as a web page. In case of adding new rules renew the webpage and you will see the newly added rules.

To report file system disk space usage:

while true ; do echo -e "HTTP/1.1 200 OK\n\n $(df -h)" | nc -l -p 8080 -q 1; done
