I am very now to DTrace land.
1) I want to write a DTrace script which takes -verbose or --verbose as an
option.
#!/usr/sbin/dtrace -s
#pragma D option quiet
pid$1::func1:entry
{
/* should be called only when verbose option is provided in command line */
printf("Entered %s ...\n", probefunc);
}
pid$1::func2:entry,
{
/* should be called always */
}
END
{
/* should be called always */
/* print out summary */
}
It should be normally run as
$./myscript.d 9149
(where 9149 is the pid of the process I want to trace)
when I want more detailed information, I should be able to run it as
$./myscript.d 9149 --verbose
Is something of this sort possible ?
2) Also I saw that END gets executed when I press Control C. But when I want to
send output to another file via tee as shown below :
$./myscript.d |tee dtrace.log
and when I press control C, it doesn't get called. Any ideas?
