Record installation responses into a response file, which is a text file you can edit to change any responses before using it in subsequent installations.
When installing in GUI or console mode, the -r command line argument records your responses to the installation wizard’s prompts and creates a response file when the installation wizard exits.
x:\setupConsole.exe -r responseFileName
where x is the location of the installer.
C:\Sybase\REP\ResponseFile.txt
