Navigate through the kernel features and menuconfig commands. Esc+Esc: Exit menuconfig or cancel the command. ↵ Enter: Activate a command, or expand a branch. y: Compile and include this feature inside of the kernel. m: Compile this feature as a module, separate from the kernel. n: Do not compile the feature. / Search configuration parameter.
Configuration Menu Language (CML) was used, in Linux kernel versions prior to 2.5.45, to configure the values that determine the composition and exact functionality of the kernel. Many possible variations in kernel functionality can exist; and customization is possible, for instance for the specifications of the exact hardware it will run on.
Linux API, Linux ABI, and in-kernel APIs and ABIs. The Linux kernel provides multiple interfaces to user-space and kernel-mode code that are used for varying purposes and that have varying properties by design. There are two types of application programming interface (API) in the Linux kernel: the "kernel–user space" API; and; the "kernel ...
Does nothing, but exits unsuccessfully groups: Prints the groups of which the user is a member hostid: Prints the numeric identifier for the current host id: Prints real or effective UID and GID: link: Creates a link to a file logname: Print the user's login name nice: Modifies scheduling priority nohup: Allows a command to continue running ...
The Linux console is a system console internal to the Linux kernel. A system console is the device which receives all kernel messages and warnings and which allows logins in single user mode. [1] The Linux console provides a way for the kernel and other processes to send text output to the user, and to receive text input from the user.
The Linux kernel also exposes the nomerges sysfs parameter as a scheduler-agnostic configuration, making it possible for the block layer's requests merging logic to be disabled either entirely, or only for more complex merging attempts. [2]
iproute2 utilities communicate with the Linux kernel using the netlink protocol. Some of the iproute2 utilities are often recommended over now-obsolete net-tools utilities that provide the same functionality. [4] [5] Below is a table of obsolete utilities and their iproute2 replacements.
ethtool is the primary means in Linux kernel-based operating systems (primarily Linux and Android) for displaying and modifying the parameters of network interface controllers (NICs) and their associated device driver software from application programs running in userspace.
