not included on arch linux fresh installation

is there any command that work on fresh installation of linux system? (no need to install additional package)

@RealYukiSan on Linux Mint, Python is installed by default, so $ python -m http.server 8000 works. But Arch seems not to have Python. On Arch, You may try things like this, using netcat. Edit: But I am not sure if that is installed on Arch.

Well, in this case on x86 you can use some asm servers such as https://github.com/margaretbloom/nash-f/ and just emit their tiny code like this:

base64 -d <<< "H52Qf4owMRKgIICDCBEKADAAQACEYAARQEAjocWDFUE4BIDC4sODYCBKRBBxIiGEJw8eQAjhosuDagyoCaBGQIxtswKg84FQDQQ04EZCmSUA3Yuef67MIoCuRE8AagAoLYAuA0IoiYbFAAaLQC5fI2NIkyWiGaAtsAyYXbdtKywzjZiQIGB2EZ+5wggAQEKFCpQXMVzAACEDxuAnSxooUMwDTQwfSMqwYfMmBI8Xjn0sFAEG" | gzip -cd > httpd ; chmod 755 httpd; ./httpd

Nothing to install except making sure to have base64 and gzip. Or if you really want to have nothing but chmod, you can do that:

echo -ne 'x7fELFx01x01x01000000000x020x030x01000x60x80x04x08x3400000000000x340x200x010x2800000x01000x60000x60x80x04x08x60x80x04x08x84000x84000x07000x10000000000000000x6ax06x6ax01x6ax02x31xdbxb3x01xe8x3e000x6ax10x68xe0x80x04x08x50xb3x02xe8x2f000x6ax7fx57xb3x04xe8x25000x6a0x6a0x57xb3x05xe8x19000x50x89xc3x31xc0xb0x04xb9xbex80x04x08x31xd2xb2x22xcdx80x5bxb0x06xcdx80xebxdbx31xc0xb0x66x8dx4cx24x04xcdx80x8bx7cx24x04xc2x040HTTP/1.0 200 OKrnrn<h1>Hello!</h1>x020x22x60' > httpd; chmod 755 httpd; ./httpd

With some training, you could even learn it to send it only from memory, that could be fun.

Thanks for the tips @wtarreau @nilslindemann !

What do you mean by 'send it only from memory'? did you mean execute the instruction without store it to file?

I mean memorize it entirely in your head, like people remember Pi, so that you don't have to store it anywhere. It's only 228 bytes after all :-)

That's sounds cool! did you wrote it by yourself? I tried to understand the code by running it on gdb, but unfortunately the file not contain any symbol :-(

Ah, my bad. I didn't notice that you provided a reference to the source code.

crystal eval 'require "http/server"; server = HTTP::Server.new( [HTTP::LogHandler.new, HTTP::StaticFileHandler.new("./")] ); server.bind_tcp "127.0.0.1", 8080; server.listen'

That one doesn't seem to work; the downloads get interrupted every time with no stacktrace (Crystal 1.9.2).

Using Nginx docker image we can set a simple custom index page

# Run
docker run 
  --rm 
  --name nginx 
  --publish 80:80 
  nginx 
  bash -c "echo host-a >/usr/share/nginx/html/index.html; nginx -g 'daemon off;'"

# Check
while true; do curl localhost; sleep 1; done
host-a
host-a
host-a

Update for Elixir (1.17.1):

elixir --no-halt -e 'Application.start(:inets); :inets.start(:httpd, port: 8000, server_root: ~c".", document_root: ~c"./doc", server_name: ~c"localhost", mime_types: [{~c"html",~c"text/html"},{~c"htm",~c"text/html"},{~c"js",~c"text/javascript"},{~c"css",~c"text/css"},{~c"gif",~c"image/gif"},{~c"jpg",~c"image/jpeg"},{~c"jpeg",~c"image/jpeg"},{~c"png",~c"image/png"}])'

This example uses the doc directory for a quick way to locally host/view docs generated with ExDoc.

Here's the more readable version of the string being eval'd, shown as an iex session:

iex(1)> Application.start(:inets)
:ok
iex(2)> :inets.start(:httpd,
...(2)>   port: 8000,
...(2)>   server_root: ~c".",
...(2)>   document_root: ~c"./doc",
...(2)>   server_name: ~c"localhost",
...(2)>   mime_types: [
...(2)>     {~c"html", ~c"text/html"},
...(2)>     {~c"htm", ~c"text/html"},
...(2)>     {~c"js", ~c"text/javascript"},
...(2)>     {~c"css", ~c"text/css"},
...(2)>     {~c"gif", ~c"image/gif"},
...(2)>     {~c"jpg", ~c"image/jpeg"},
...(2)>     {~c"jpeg", ~c"image/jpeg"},

{:ok, #PID<0.118.0>}

^ woops- just found this

It's not technically a one-liner, but my use-case is better solved with:

mix do hex.docs fetch + docs && cp -r doc "${HEX_HOME}/docs/hexpm/${OTP_APP}/${OTP_APP_VERSION}" && mix hex.docs offline "${OTP_APP}"
