Below is the list of commands implemented
| Syntax | Meaning |

| command >> filename | If the filename already exists append the stdout output, otherwise, create a new file |
| 1>filename | redirect stdout to filename |
| 2>filename | redirect stderr to filename |
| 2>&1 | redirect stderr to stdout |
| command < filename | use file descriptor 0 (stdin) for filename. If command tries to read from stdin, effectively it will read from filename. |
