    hello_grep [FLAGS] [OPTIONS] <pattern> [path]...

FLAGS:
    -i, --ignore-case            Make search case insensitive
    -c, --count                  Suppress normal output; instead print a count of matching lines for each input file.
        --color                  Activate color in output.
    -l, --files-with-matches     Suppress normal output; instead print the name of each input file from which output
                                 would normally have been printed. The scanning will stop on the first match.
    -L, --files-without-match    Suppress normal output; instead print the name of each input file from which no output
