    printf '\e[%s;3%dm' "$1" "$2" 
}

}

### Colorful echo; echo + color
### Usage: echolor [attr] [color] [arbitrary messages...]

if [ ! -f "${inputPath}" ]; then
    printf "[ %s ][ %s ] The database file '%s' doesn't exist!\n[ %s ] For help, run %s\n" \
        "${hostScript}" "$(echolor $bold $magenta ERROR)" \
        "${inputPath}" \
        "${hostScript}" "$(echolor $reverse $cyan "${hostScript}" -?)" && \
    exit 1
