Remove package using terminal on Mac
I installed a package (asciiart) a while ago but it appears that it did not install properly or is currently not working due to updates. Even the help command doesn't appear to be working:
$ asciiart -h

I believe I might have installed the package using chmod from a .tar.gz file that I downloaded.
I couldn't find any documentation to remove this package. Is it possible to remove this package so that the `asciiart` command will not be recognized (i.e. I will get the standard `-bash: asciiart: command not found` error message instead)?
