## ascii-art-output
### Objectives
- You must follow the same [instructions ](../README.md ) as in the first subject **while** writing the result into a file.
The file must be named by using the flag `--output=<fileName.txt>` , in which `--output` is the flag and `<fileName.txt>` is the file name which will contain the output.
- The flag must have exactly the same format as above, any other formats must return the following usage message:
```console
Usage: go run . [STRING] [BANNER] [OPTION]
EX: go run . something standard --output=< fileName.txt >
```
### Instructions
