it gets all parameters, you can then use GetOptions to check for specific parameters.

how i do it:

1) includes:

!insertmacro GetParameters
!insertmacro GetOptions

2) oninit:

Function .onInit

    ; Get parameters

        var /GLOBAL cmdLineParams
        Push $R0

        ${GetParameters} $cmdLineParams

        ; /? param (help)
        ClearErrors
        ${GetOptions} $cmdLineParams '/?' $R0
        IfErrors +3 0
        MessageBox MB_OK "list all command line options here!"
        Abort

        Pop $R0

    ; Initialise options

        Var /GLOBAL option_runProgram
        Var /GLOBAL option_startMenu
        Var /GLOBAL option_startMenuAllUsers
        Var /GLOBAL option_shortcut
        Var /GLOBAL option_shortcutAllUsers

        StrCpy $option_runProgram         1
        StrCpy $option_startMenu          1
        StrCpy $option_startMenuAllUsers  0
        StrCpy $option_shortcut           1
        StrCpy $option_shortcutAllUsers   0

    ; Parse Parameters

        Push $R0
        Call parseParameters
        Pop $R0

FunctionEnd

3) parseParameters function:

Function parseParameters

    ; /norun
    ${GetOptions} $cmdLineParams '/norun' $R0
    IfErrors +2 0
    StrCpy $option_runProgram 0

    ; /nostartmenu
    ${GetOptions} $cmdLineParams '/nostartmenu' $R0
    IfErrors +2 0
    StrCpy $option_startMenu 0

    ; /starmenuallusers
    ${GetOptions} $cmdLineParams '/startmenuallusers' $R0
    IfErrors +2 0
    StrCpy $option_startMenuAllUsers 1

    ; /noshortcut
    ${GetOptions} $cmdLineParams '/noshortcut' $R0
    IfErrors +2 0
    StrCpy $option_shortcut 0

    ; /shortcutallusers
    ${GetOptions} $cmdLineParams '/shortcutallusers' $R0
    IfErrors +2 0
    StrCpy $option_shortcutAllUsers 1

FunctionEnd

Thanks theblazingangel for the reply. Could you please tell me where we give the command line parameters for a .nsi file? Is it like
abc.nsi /norun

Also is it possible to give command-line parameters like in any other files.... like

xyz.c "1" "abcd"
Here "1" and "abcd" are cmd-line parameters. Is a similar thing possible in abc.nsi file??

Thanks,
Ramya

no no no, you don't pass the command line parameters to a .nsi file, you compile the .nsi file into a .exe and then you can pass the parameters to the .exe you've made.
