Using the –t option to specify the thread, you can get the information specific to a thread without
stopping the other threads as shown below.
Example 8 Printing the output for a sample threaded process with the -t option

A special argument -1 enables you to trace the calling process without entering the PID of the
process. Hence, you can skip the process of finding the PID by using this argument on a calling
process.
The example below shows the usage of special argument -1 that can be used to run pstack on
the calling process. In this case, the calling process is the shell itself.
