The first command shell was 'sh', the Bourne shell (Steven Bourne).

In an interactive shell session the shell program waits for the user to type in a command. When receiving a command the shell program will then attempt to locate it and process (execute) the command. You are interacting with the shell.

Running a shell file requires a pre-stored series of commands stored in a file. Unless the shell program you are running is interactive then the shell executes each command in sequence, without involving the user at all.

While the command is executing, the shell waits for the process to finish.

The output would be 'shell shell' (without the quotes, of course)

echo $SHELL

While the command is executing, the shell waits for the process to finish.

Typically the 'exit' command gets you out of the current shell environment you are in; if this is the login shell then you will be logged out of the system.

The echo command echoes out any of the command line arguments given to it. It is commonly used in shell scripts to echo what portions of the shell script are doing.

Windows shell commor is also known as Windows shell common. This term refers to a type of command that allows you to access folders through the desktop or command search.

There isn't a concept of a 'default' shell in Unix; you may have a login shell specified by the system administrator for use when you log in. Although it isn't a fool-proof way to find your shell, you could use the command:

echo $SHELL

or use the 'finger' command to see what your default login shell environment is. You could also 'grep' for your information in the password file because the last field is your login environment shell.

The 'cp' command is a primitive command; there isn't anything really in the shell to accomplish this. You could use other commands for 'cp' (such as 'cat') but those are also primitive commands.

Your login shell can be changed by using the chsh or ypchsh command.

'set' commands vary depending on what shell program you are using. All of them (for each shell) are documented in the 'man' command or 'info' command for that shell. For example, 'man csh', et al.

The trap command is used in a shell script to intercept certain types of software signals; usually it is used to do a "graceful" cleanup when the shell program is interrupted.

Command substitution is a feature in shell scripting that allows the output of a command to be used as an argument in another command. This is typically done by enclosing the command in backticks (`command`) or using the syntax $(command). The shell executes the command inside the substitution and replaces it with its output, enabling dynamic command composition and data processing. This technique is commonly used for capturing the results of commands and using them in scripts or command-line operations.

The default command shell in Fedora is typically Bash (Bourne Again SHell). Bash is a widely used shell that provides a powerful command-line interface for users to interact with the operating system. While other shells like Zsh or Fish can be installed and configured, Bash remains the default for most Fedora installations.

The shell prompt is the visual aspect of the shell between running programs, th epart that shows it is waiting for you to give it a command.

The Korn shell is a command interpretor that combines the syntax and abilities of the csh shell and the sh (Bourne) shell. It was designed by David Korn of Bell Labs.

bash is located in /bin/bash.

A bashism is a shell command specific to the Bash interpreter.

its a command prompt shell, must be there if you want to use command prompt

The 'exit' command allows you to stop a running shell script at any point and to return a "status" value back to whomever called the shell script. This is a very common practice with shell scripts; sometimes you want to stop the script before it gets to the end of the shell script (for various logic reasons).

The 'exit' command also allows you to give a status that any other calling process can use to determine if the shell script ended successfully or not.

It depends on the shell interpreter you are using, but in general the I/O redirection operators are >, >>, |.

On a computer Bash is a Unix shell and command language.

The name of your login shell is set when you log in - check the $SHELL environment variable. Note that this is a changeable environment variable so it isn't always accurate.

You could also use the 'finger' command or 'grep' through the password file to see what your login shell environment will be set to.

However, if you are in a subshell or child shell, you will need to check on the shell environment with the 'ps' command to see what the shell currently running might be.

If the shell script is readable and executable then to execute it just type the name of the shell script file. Otherwise, you can explicity call a shell interpreter to run the file as a shell script, i.e.,

ksh myfile

To find the shell on a computer, you can open a terminal or command prompt application. In Windows, you can use Command Prompt or PowerShell, while in Unix-based systems (such as Linux or macOS), you can use the Terminal application. These applications provide a command-line interface to interact with the operating system.

The bash (short for Bourne Again Shell) is a popular command shell for Linux and Unix-like systems. It's name comes from the Bourne Shell, an old shell found on many older Unix systems. bash is a free reimplementation of that shell.

Safe mode with command prompt option is totally depends on DOS shell, hence there is no need for separate command prompt..

Internal commands are executed by the shell and do not exist as a separate binary program. You can find out which of these there are by looking at the 'man' entry for the shell you are using.

External commands can be found in various directories, such as /bin, /usr/bin, etc.

The a default Unix shell is the shell that comes with and is activated initially with your distribution of Unix. The shell is essentially the program the runs the command line interface allowing someone to interact with their computer. Some examples are the Bourne-Again shell (bash) or the Bourne shell (sh).

The common shell variables differ according to which shell you are talking about. In general, they control the shell environment behavior, terminal behavior, and other external things.

You can get a list per shell by using the 'man' command with the shell name to list out the common variables used in that shell environment.

Use the builtin 'echo' or 'print' command followed by the shell variable name, which will substitute the value when printed/displayed.

Slapping a Soldier Patton is relieved of command for slapping a shell-shocked soldier in an Army hospital.

Essentially, a command in Unix is a program that you execute for a certain purpose. It could be anything, from a shell script, to copying or deleting files, etc.

A shell program is called a command processor because it has to process commands according to what the user wishes to do. Along with executing commands as specified by the user it also has its own programming language and can be instructed to do things programmatically.
