Shell
This Project is Part of My Operating System Lab (OS Lab)
### Following Are The Key Points of Project
### 1) Shell
A Shell provides you with a CLI (Command Line Interface) interface. It
gathers input from you and executes programs based on that input. When
a program finishes executing, it displays that program's output.
Shell is an environment in which we can run our commands, programs, and
shell scripts. There are different flavors of a shell, just as there are different
flavors of operating systems. Each flavor of shell has its own set of
recognized commands and functions.
### 2) Working of Shell
Shell reads your input after you press Enter. It determines the command
you want executed by looking at the first word of your input. A word is an
unbroken set of characters. Spaces and tabs separate words.
### 3) Examples of Shell
There are many shells available in different operating systems.
Few of them are given below
* Linux Shell
* Command Prompt
* PowerShell
* The Bourne Sell for Solaris
The Shell that we have implemented is basically a simples shell, which works
very similer to the shell tha we use in th ubuntu operating system
The Shell is named as `Pearl`
### 3.1) How to Run
In Order to Run This Project. Just Open Linux Terminal In Same Folder and Type
```c
gcc Shell.c
```
and Press Enter and Type
```c
./a.out
```
### 4) Basic Layout of `Pearl`
The commands that we have implemented in this shell are given below
* help
* man
* leave
* pwd
* whoami
* echo
* color
* bgcolor
* crdir
* deldir
* cd
* ls
* ls –all
* ls –tree
* del
* cat
* touch
* copy
### 5) Cat Command
cat commands is implemented. The working of this command is to read the
content of file and also write the content into the file.
```c
//Read Format
cat FILENAME.txt
//Write Format
cat > FILENAME.txtCat Read
```
### 6) CD Commands
CD Commands is Refferred as Change Directory Command , this is use to
move from one directory to another directory. We can move to the parent
directory by command of cd ..
```c
// Syntax:
cd New
cd ..
cd .
cd Folder#1
```
### 7) CRDIR & DELDIR
These both command are used to create the directory and delete directory.
Borth commands are multi-arguments. We can give one or more than one
argument to this commands. This is helpful in creating and deleting multiple direcroties at a time
```c
// Syntax:
crdir Folder#1
crdir Folder#2
deldir Folder#1
deldir Folder#2
```
### 8) LS Command
LS commad is used to list all files and folder names in the current directory. This is implemented in three ways
```c
ls
// This is very simple , this only show the folder of files in the current directory
ls –tree
// This command is used to show the all files and folder inside a current folder . this works recursively and check every fil and folder
ls –all
// This command is very similer to the simple ls commands , but provides us with the additional information including the files or folder access rights , size and creation date etc
```
### 9) Man Command
Man keyword is short form manual , this command is used to get the deep
information about command.
```c
// Syntax:
man wipe
//give manual of wipe command used to clear the screen
man color
//give manual color command
man copy
//give manual of copy commandHelp Command:
```
### 10) Help Command
Help command is used to know that which command are supported by this
shell and and detailed preview of the command syntax, which is helpful for new user. Just type `help` in terminal to run this commmand.
