Getting stacktrace of all threads without attaching GDB

Question

Is there a way to print stacktrace of all threads without attaching GDB?

Or is there a command which I can use as gdb batch mode to print stacktrace of all threads?

Answer 1

pstack?

Usage:

pstack 

From the man page:

pstack - print a stack trace of a running process
...
If the process is part of a thread group, then pstack will print out a stack trace for each of the threads in the group.
