kleines Filmröllchen 98c0c5e9e6 Help+Base: Add help://man URLs for links between man pages 
The URLs of the form `help://man/<section>/<page>` link to another help
page inside the help application. All previous relative page links are
replaced by this new form. This doesn't change any behavior but it looks
much nicer :^)

Note that man doesn't handle these new links, but the previous relative
links didn't work either.

Name

bt - view the backtrace of the specified process

Synopsis

$ bt <pid>

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
