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.
The database and FUSE-based Proxmox Cluster file system (pmxcfs [31]) makes it possible to perform the configuration of each cluster node via the Corosync communication stack with SQLite engine. [13] Another HA-related element in PVE is the distributed file system Ceph, which can be used as a shared storage for guest machines. [32]
Some versions of Unix and Linux contain Bash system startup scripts, generally under the /etc directory. Bash executes these files as part of its standard initialization, but other startup files can read them in a different order than the documented Bash startup sequence.
A Unix shell is a command-line interpreter or shell that provides a command line user interface for Unix-like operating systems. The shell is both an interactive command language and a scripting language , and is used by the operating system to control the execution of the system using shell scripts .
A restricted mode is part of the POSIX specification for shells, and most of the Linux/Unix shells support such a mode where several of the built-in commands are disabled and only external commands from a certain directory can be invoked. [72] [73] PowerShell supports restricted modes through session configuration files or session ...
The Bourne shell (sh) is a shell command-line interpreter for computer operating systems.It first appeared on Version 7 Unix, as its default shell. Unix-like systems continue to have /bin/sh—which will be the Bourne shell, or a symbolic link or hard link to a compatible shell—even when other shells are used by most users.
Windows PowerShell, a command processor based on .NET Framework. PowerShell, a command processor based on .NET; Hamilton C shell, a clone of the Unix C shell by Hamilton Laboratories; Take Command Console (4NT), a clone of CMD.EXE with added features by JP Software; Take Command, a newer incarnation of 4NT
Many Unix shells also offer a builtin exec command that replaces the shell process with the specified program. [1] Wrapper scripts often use this command to run a program (either directly or through an interpreter or virtual machine ) after setting environment variables or other configuration.
