The Linux kernel handles all operating system processes, such as memory management, task scheduling, I/O, interprocess communication, and overall system control. This is loaded in two stages – in the first stage, the kernel (as a compressed image file) is loaded into memory and decompressed, and a few fundamental functions are set up such as ...
The dump command is a program on Unix and Unix-like operating systems used to back up file systems. It operates on blocks, below filesystem abstractions such as files and directories. Dump can back up a file system to a tape or another disk. It is often used across a network by piping its output through bzip2 then SSH.

These files can be viewed as text, printed, or analysed with specialised tools such as elfdump on Unix and Unix-like systems, objdump and kdump on Linux, IPCS (Interactive Problem Control System) on IBM z/OS, [8] DVF (Dump Viewing Facility) on IBM z/VM, [9] WinDbg on Microsoft Windows, Valgrind, or other debuggers.
MySQL ships with many command line tools, from which the main interface is the mysql client. [123] [124] MySQL Utilities is a set of utilities designed to perform common maintenance and administrative tasks. Originally included as part of the MySQL Workbench, the utilities are a stand-alone download available from Oracle.
These typically embed the location and type of the root file system. Other Linux distributions (such as Fedora and Ubuntu) generate a more generic initrd image. These start only with the device name of the root file system (or its UUID) and must discover everything else at boot time. In this case, the software must perform a complex cascade of ...
Kickstart is normally used at sites with many such Linux systems, to allow easy installation [2] and consistent configuration of new computer systems. Kickstart configuration files can be built three ways: By hand. By using the GUI system-config-kickstart tool. By using the standard Red Hat installation program Anaconda.
In the event of a kernel crash, kdump preserves system consistency by booting another Linux kernel, which is known as the dump-capture kernel, and using it to export and save a memory dump. As a result, the system boots into a clean and reliable environment instead of relying on an already crashed kernel that may cause various issues, such as ...
