This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.

In a September 2014 ZDNet interview, prominent Linux kernel developer Theodore Ts'o expressed his opinion that the dispute over systemd's centralized design philosophy, more than technical concerns, indicates a dangerous general trend toward uniformizing the Linux ecosystem, alienating and marginalizing parts of the open-source community, and ...
Linux portal; kdump (Linux) – Linux kernel's crash dump mechanism, which internally uses kexec; kGraft – Linux kernel live patching technology developed by SUSE; kpatch – Linux kernel live patching technology developed by Red Hat; Ksplice – Linux kernel live patching technology developed by Ksplice, Inc. and later bought by Oracle
The clients can issue commands to the control daemon, which would accept and divide the workload to the computing daemons. For clients, the main commands are srun (queue up an interactive job), sbatch (queue up a job), squeue (print the job queue) and scancel (remove a job from the queue). Jobs can be run in batch mode or interactive mode. For ...
It was modeled after the Multics shell, developed in 1965 by American software engineer Glenda Schroeder. Schroeder's Multics shell was itself modeled after the RUNCOM program Louis Pouzin showed to the Multics Team.
