Pstack is a shell script that prints stack trace information for running processes. It is actually a link to gstack, while gstack itself is a shell script encapsulated by gdb.

This command displays the stack trace for each process. The pstack command must be run by the owner or root of the corresponding process. You can use pstack to determine where the process is suspended. The only option allowed by this command is the PID of the process to be checked.
