in reply to Double Qoutes in string command

Read perlop, especially the Quote and Quote like Operators section. You do not need double quotes here, as there is nothing to interpolate, so you can switch to single quotes:
my $string = 'sysBootFileWrite "QSDvxWorks.aif"';

For cases where interpolation is needed, you can backslash the inner double quotes or use the qq operator:

print "He said, \"Hello, $darling.\""; print qq(He said, "Hello, $darling.");
