Hey Vladimir, This is a bug in the way that DTrace composes arguments to the command it executes as a result of the -c option.
http://src.illumos.org/source/xref/illumos-gate/usr/src/cmd/dtrace/dtrace.c#274 You can see that make_argv() just tokenizes the string based on whitespace -- it doesn't use the tokenizing logic that the shell would use. dtrace(1M) should probably do something like libast`sfnew() of the command string, followed by an libshell`sh_parse() and libshell`sh_exec() -- i.e. we want dtrace -c to act like sh -c. I've filed this bug to track the issue: https://www.illumos.org/issues/1440 To work around this, you can probably create a shell script that simply does an exec of the command you want to run with the arguments you want.
