source Command Generator

## What is source?

The `source` command (also written as `.`) reads and executes a script **in the current shell** rather than a subshell. This means any variables, functions, or aliases the script defines stay available after it finishes. It is the standard way to reload shell configuration and load environment setup files.

## How to Use

1. **Set the File**: Enter the path to the script (e.g., `~/.bashrc`, `./setup.sh`). 2. **Add Arguments** (optional): Pass positional arguments the script expects (e.g., `arg1 arg2`). 3. **Copy & Run**: Paste the generated command into your terminal. Changes take effect immediately in the current shell.

### Positional file argument

`source` takes the script path as its first argument: `source ~/.bashrc`.

### Positional arguments

Any remaining tokens become `$1`, `$2`, ... inside the script: `source ./setup.sh dev` makes `$1=dev` available within `setup.sh`.

### The `.` synonym

In POSIX shells, `.` is the same command: `. ~/.bashrc` is identical to `source ~/.bashrc`. Use `source` in Bash/Zsh for readability; use `.` for portability.
