How Linux looks at the stack of a process

There are two ways of doing this:

First: Pstack process ID Second, use GDB and then attach the process ID, then use the command thread apply all BT Third: Strace-f-P pid the method and Pstack similar

Part IV: Gcore PID, output core file, gdb cmd corefile

Both methods can list the current call stack for all threads in the process.

However, using GdB's methods, you can also view certain information, such as local variables, pointers, and so on.

However, Pstack is handy if you look at the call stack only.

Pstack is not a link program, so there is no need for other library support, this is centos5.8 Pstack:pstack.rar
Copy can be used directly in the past.
