Description

This program is used to inspect the current executable state of a process. It will read the stack of each thread in the process, and symbolicate the addresses for each frame in the stack producing a backtrace.

NOTE:

• Kernel addresses will not be available unless you are super user.

• If Kernel addresses are available, they will not be symbolicated unless the current user has access to the /boot/Kernel file.

Arguments

• pid: Process ID

Examples

View all stacks of pid number 10:

$ bt 10

Use watch(1) to emit a backtrace of pid 124, every second:

$ watch -n 1 -- bt 124
