# Unix Shell Implementation using C Multithreading
This is a Linux/Unix-like shell implemented in C. This shell supports 3 internal and 5 external commands with various options, executed via `fork/exec` or `pthread/system` function calls based on the user's preference. Commands can be run in parallel using threads, making this shell very efficient.
## Features
### Internal Commands
#### 1. echo (prints the arguments provided)
- `-n`: No newline after execution.
- `-E`: Suppress backslash interpretation.
#### 2. pwd (prints the current directory)
- `-L`: Do not ignore symbolic links.
- `-P`: Avoid symbolic links.
#### 3. cd (changes the current directory of the process)
### External Commands
#### 1. ls (lists the directories in the current directory)
- `-1`: Print directories on new lines.
- `-Q`: Print directories in quotation marks.
#### 2. date (prints the current date)
#### 3. cat (displays the content of a file)
- `-n`: Display line numbers.
- `-e`: Display `$` at the end of each line.
#### 4. rm (removes a file)
- `-i`: Ask for confirmation before removal.
- `-v`: Display the status of removal.
#### 5. mkdir (creates a new directory)
- `-v`: Display the status of directory creation.
