Hi! I''m a dtrace newbie. Is there a way to change the format of a
timestamp? For example now I have this output with
printf("%Y",timestamp):
"2008 Nov 4 15:44:37"
I would like to have this kind of output instead:
"2008-11-4 15:44:37"
How can I obtain it?
Thanks!

Nope, sorry. Sounds like a good RFE for a -x option. Adam On Nov 4, 2008, at 6:55 AM, Davide Vanoni wrote:> Hi! I''m a dtrace newbie. Is there a way to change the format of a > timestamp?

Hi, Is it possible to get know endianness on the solaris target by using dtrace? Best Regards, /Mitsu
> Is it possible to get know endianness on the solaris target by using > dtrace?My first suggestion would be to find a C preprocessor directive that''d tell you the answer. Lacking that, you could do something like: #!/usr/sbin/dtrace -Cs /* Look for little-endian archs and set appropriately. */ #ifdef i386 #define LITTLE_ENDIAN #endif ::ip_input:entry { #ifdef LITTLE_ENDIAN printf("Little!\n"); #else printf("Big!\n"); #endif exit(0); } Dan

Hi Dan, Thanks for your suggestion! I am not frequent user of dtrace. So I can rely on the C preprocessor and perform like C program. And I wonder if there is any solaris command to get such information.

That''s a good question. I''m not aware of a quick-and-dirty command that returns the endian value, but it should be simple enough to write one. Dan
