One command line web server on port 80 using nc (netcat)

nc -kl 5432 -c 'echo -e "HTTP/1.1 200 OK\r\n$(date)\r\n\r\n";echo "<p>How are you today?</p>"'

-k, --keep-open will keep connection alive, and we could exclude using 'while true' nc is such a powerful command, it could be used instead of any OS! :p

Sample Output

/home/me> curl -i localhost:5432
HTTP/1.1 200 OK
Tue Nov 12 15:40:27 EET 2013


<p>How are you today?</p>

One command line web server on port 80 using nc (netcat)

Very simple web server listening on port 80 will serve index.html file or whatever file you like pointing your browser at http://your-IP-address/index.html for example. If your web server is down for maintenance and you'd like to inform your visitors about it, quickly and easily, you just have to put into the index.html file the right HTML code and you are done! Of course you need to be root to run the command using port 80.
This is sample output - yours may be different.

while true ; do nc -l 80 < index.html ; done

What Others Think

I don't have the '-c' parameter available, which Netcat version are you using?.
