Most of the Unix command names are short, single words in lowercase. The commands are
basically programs written in C. Traditionally, Unix system programs are stored in directories
called /bin and /usr with additional programs usually used only by system administrators in
/etc and /usr Many versions of Unix also have programs stored in /usr
yes it is stored in CMOS
The answer varies on system and kernel configuration settings, but you can string together a lot of commands. The maximum path on several systems is at least 1024 characters, which can include a lot of commands. Ultimately, however, it depends on system resources.
System-wide configuration files are usually found in /etc. Personalized configuration files are stored in the user's home directory, in files and subdirectories preceded by a "." in their name.
Internal commands are built into the command interpreter of an operating system, allowing them to be executed without requiring a separate program file. They typically include commands for file management, system configuration, and process control, such as cd, dir, or echo. Unlike external commands, internal commands do not rely on external executables, making them faster to execute and often essential for basic system operations. Additionally, they operate directly within the command shell environment.
In a UNIX operating system, system administrators use a variety of commands to manage and maintain the system. Key commands include ls for listing files, chmod for changing file permissions, useradd to create new user accounts, and passwd to manage user passwords. Other important commands include df and du for disk usage analysis, ps for monitoring running processes, and kill to terminate processes. These commands are essential for system configuration, security, and performance monitoring.
Becoz the configuration cannot be changed..........
Configuration data refers to the settings and parameters that determine how a system or application operates. This data is often stored separately from the actual software code to allow for easier customization and flexibility. Configuration data can include things like user preferences, system settings, and connection details.
Configuration files are typically stored in the /etc directory. They can, of course, be anywhere the implementer wishes them to be as long as the process knows where to find them.
Stored energy is called potential energy. This energy is typically associated with an object's position relative to other objects or the internal configuration of a system. When the object or system is in motion, the potential energy can be converted into kinetic energy.
Boot Configuration Data (BCD) is stored in a file called BCD located in the \Boot directory of the system partition on Windows operating systems. This partition is typically marked as active and may not have a drive letter assigned. The BCD file contains boot configuration parameters and controls how the operating system is started. It can be accessed and modified using tools like bcdedit in the command prompt.
In DOS (Disk Operating System), commands can be categorized into two main types: internal and external commands. Internal commands are built into the command interpreter (COMMAND.COM) and are available at all times, such as DIR, COPY, and DEL. External commands, on the other hand, are not part of the command interpreter and are stored as separate executable files, including utilities like FORMAT, CHKDSK, and DISKCOPY. Additionally, commands can also be classified based on their functionality, such as file management, system management, and network commands.
