Yum show every available version of a package

yum --showduplicates list [package]

Should be called --all-versions instead.

Quickly use a webserver to serve a local directory

Steps:

• sudo yum install lighttpd
• # Create a file containing:
  
  

  server.document-root = "/path/to/your/directory/here/" 
  
  server.port = 3000
  
  mimetype.assign = (
    ".html" => "text/html", 
    ".txt" => "text/plain",
    ".jpg" => "image/jpeg",
    ".png" => "image/png" 
  )
  
  

• lighttpd -t -f lighttpd.conf # check config
• lighttpd -D -f lighttpd.conf # run webserver
