Consider the following:
thomas@dev:~/ovas/openvas-libraries-3.1.0/nasl$ cat ~/string.nasl
display("Single quoted constant:\n");
a = 'hi\n';
display(a);
display("[", strlen(a), "]\n");
display("Double quoted constant:\n");
a = "hi\n";
display(a);
display("[", strlen(a), "]\n");
display("Single quoted string():\n");
a = string('hi\n');
display(a);
display("[", strlen(a), "]\n");
display("Double quoted string():\n");
a = string("hi\n");
display(a);
display("[", strlen(a), "]\n");
thomas@dev:~/ovas/openvas-libraries-3.1.0/nasl$ ./openvas-nasl -X
~/string.nasl
** WARNING : packet forgery will not work
** as NASL is not running as root
Single quoted constant:
hi
[3]
Double quoted constant:
hi
[4] <------------------------- Watch out! -----
Single quoted string():
hi
[3]
Double quoted string():
hi
[3]
So it looks like 'hi\n' == string("hi\n") from what I can tell, but
"hi\n" != string("hi\n")
Thomas.
P.S. ./openvas-nasl help functions appear wrong with the -X option -
notation is reversed. Run with -X to run in unauthenticated mode
(I think) - but I may be missing something else here.
