Download script - implementation tips

  • Use a version control system

    • installation scripts
    • installation property files
    • binaries (curl, wget, etc)
    • config_override

  • A single generic installation script for all installations.

  • A separate installation property file per installation

Download

Use wget or curl, should rely only on a single file, not on any installation. It is also possible to use powershell - http://superuser.com/questions/362152/native-alternative-to-wget-in-windows-powershell.
