Does DTrace script only support "#pragma D option ..", not "-x option"?

[Nan Xiao]

Hi all,

My FreeBSD version is 11.0, and I write a simple DTrace script:

#!/usr/sbin/dtrace -s -x dynvarsize=64m

dtrace:::BEGIN
{
        printf("Hello FreeBSD!\n");
}

Running it will generate following error:

dtrace: failed to open  -x dynvarsize=64m: No such file or directory


So does DTrace only support using "#pragma D option dynvarsize=64m" format
in script? I remembered Solaris can support both formats.

Thanks!
