ascii-art-output

Objectives

• You must follow the same instructions 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:

Usage: go run . [OPTION] [STRING] [BANNER]

EX: go run . --output=<fileName.txt> something standard

If there are other ascii-art optional projects implemented, the program should accept other correctly formatted [OPTION] and/or [BANNER].
Additionally, the program must still be able to run with a single [STRING] argument.

Instructions

• Your project must be written in Go.
• The code must respect the good practices.
• It is recommended to have test files for unit testing.

Usage

$ go run . --output=banner.txt "hello" standard
$ cat -e banner.txt
