4. Using MDB Commands Interactively
9. Debugging With the Kernel Memory Allocator
Summary of MDB Command-Line Options
The following operands are supported:
Specifies an ELF format object file to examine. mdb provides the ability to examine and edit ELF format executables (ET_EXEC), ELF dynamic library files (ET_DYN), ELF relocatable object files (ET_REL), and operating system unix.X symbol table files.
Specifies an ELF process core file (ET_CORE), or an operating system crash dump vmcore.X file. If an ELF core file operand is provided without a corresponding object file, mdb will attempt to infer the name of the executable file that produced the core using several different algorithms. If no executable is found, mdb will still execute, but some symbol information may be unavailable.
Specifies the numeric suffix that represents a pair of operating system crash dump files. For example, if the suffix is 3, then mdb should examine the files unix.3 and vmcore.3. If these files do not exist, but vmdump.3 does exist, then a message displays telling you to first run the following command to uncompress the dump file.
# savecore -f vmdump.3
The string of digits is not interpreted as a suffix if an actual file of the same name is present in the current directory.
