Part of my controlDict looks like:

functions
{
    ...
    fileUpdate1
    {
        type            timeActivatedFileUpdate;
        functionObjectLibs ( "libutilityFunctionObjects.so" );
        writeControl    timeStep;
        writeInterval   1;
        fileToUpdate    "./Ur/system/controlDict";
        timeVsFile      ( ( -1 "./Ur/system/controlDict_1" ) ( 0.8 "Ur/system/controlDict_2" ) );
    }
}

And I'd like to change the entry timeVsFile using below command:

foamDictionary ./Ur/system/controlDict -entry functions.fileUpdate1.timeVsFile -set "( ( -1 "./Ur/system/controlDict_1" ) ( $A "./Ur/system/controlDict_2" ) )"

But I always receive the error " No such file or directory". I think it is related with the usage of double quotes in the string.

Any idea is welcome~ Thanks!
