NAME

pycrash - a Linux kernel crash dump debugger written in Python

SYNOPSIS

pycrash [options] <vmlinux> <vmcore>

DESCRIPTION

The pycrash utility is a Linux kernel crash debugger written in Python. It improves upon the original crash tool by adding support for symbolic backtraces and in that it is easily extensible by the user.

In order to operate properly, full debuginfo is required for the kernel image and all modules in use.

OPTIONS

-d|--search-dir <directory>

Specify a directory to search recursively for modules or debuginfo for the kernel or modules.

This option may be specified multiple times.

--gdb

Start the gdb instance used with crash-python within gdb.

This option is primarily intended for debugging gdb issues.

--valgrind

Start the gdb instance used with crash-python within valgrind.

This option is primarily intended for debugging gdb issues.

EXIT STATUS

pycrash returns a zero exit status if it succeeds. Non zero is returned in case of failure.

AVAILABILITY

pycrash is part of crash-python. Please refer to the GitHub repository at https://github.com/jeffmahoney/crash-python for more information.
