Accessing command line arguments in NSIS

Question

I am trying to make my setups scripts modular. I am calling setup exe's from within main setup script based to the requirements. I want to pass command line arguments to the exe being called. Can someone please tell me how to access the command line arguments in the script being called.

Thanks in advance.

Answer 1

you can use GetOptions function (FileFunc.nsh must be included above). Following example shows p parameter reading; its value is saved into the variable. $CMDLINE is your command line (absolute or relative, as you called) containing also your parameters.

!include FileFunc.nsh

Var variable    
${GetOptions} $CMDLINE "/p" $variable

Just to define ' Var variable' before the call. – Ulises

Use GetParameters instead of $CMDLINE, as the latter contains the exe name which can get in the way. See example here. – Hardman

Answer 2

Try to get options from Command line by their name: http://nsis.sourceforge.net/Get_command_line_parameter_by_name
