I use webrick all the time!
Well, I wrote a little script called "quickhttpd" which fires off
a web server on some high port which serves up documents in the
current directory. This is very handy for all those software
packages which come with a pile of HTML, when I don''t feel like
copying it to an actual web page.
Here it is, it''s pretty tiny:
#!/opt/bin/ruby
require ''webrick''
port=rand(2048)+8192;
server=WEBrick::HTTPServer.new(:Port => port,:DocumentRoot => Dir::pwd,
:BindAddress => ''0.0.0.0'', :AccessLog => [ [ nil, nil ] ],
:Logger => WEBrick::Log.new(File.open("/dev/null","w"),nil)
)
trap "INT" do server.shutdown; exit ; end
print "http://"+`uname -n`.chomp+":#{port}/\n"
server.start
It outputs the URL of the web page which you can go to to read
whatever you were trying to read. It''s handy if you''re running
Unix-type browsers because you can just double-click on the URL in
your terminal program, then middle-click on the web browser to go
to the URL.
In sysadminland, though, mostly I toss off quick one-liners.
