    -n VAR - True if the length of VAR is greater than zero.
    -z VAR - True if the VAR is empty.
    STRING1 = STRING2 - True if STRING1 and STRING2 are equal.
    STRING1 != STRING2 - True if STRING1 and STRING2 are not equal.
    INTEGER1 -eq INTEGER2 - True if INTEGER1 and INTEGER2 are equal.
    INTEGER1 -gt INTEGER2 - True if INTEGER1 is greater than INTEGER2.
    INTEGER1 -lt INTEGER2 - True if INTEGER1 is less than INTEGER2.
    INTEGER1 -ge INTEGER2 - True if INTEGER1 is equal or greater than INTEGER2.
    INTEGER1 -le INTEGER2 - True if INTEGER1 is equal or less than INTEGER2.
    -h FILE - True if the FILE exists and is a symbolic link.
    -r FILE - True if the FILE exists and is readable.
    -w FILE - True if the FILE exists and is writable.
    -x FILE - True if the FILE exists and is executable.
    -d FILE - True if the FILE exists and is a directory.
    -e FILE - True if the FILE exists and is a file, regardless of type (node, directory, socket, etc.).
