How To Access Data With cURL And Wget

When using cURL or Wget to access data over HTTP from a web server configured for Earthdata Login authentication.

Step-by-step guide

1. Make sure you have granted user profile access permissions to the website your are downloading data from. The website
   should have instructions on how to do this.
   
   
2. Configure your username and password for authentication using a .netrc file
   
     > cd ~
  > touch .netrc
  > echo "machine urs.earthdata.nasa.gov login <uid> password <password>" > .netrc
  > chmod 0600 .netrc
   
   where <uid> is your Earthdata Login username and <password> is your Earthdata Login password.
   
   
3. Create a cookie file. This will be used to persist sessions across individual cURL/Wget calls, making it more efficient.
   
     > cd ~
  > touch .urs_cookies
   
   
4. Download your data.
   
   Using cURL:
   
     > curl -b ~/.urs_cookies -c ~/.urs_cookies -L -n http://server/path
   
   or Wget:
   
     > wget --load-cookies ~/.urs_cookies --save-cookies ~/.urs_cookies --keep-session-cookies http://server/path
   
   Note that you may supply additional options to control the output location.
