> Add option {{-q}} to "hdfs dfs -ls" to print non-printable characters as "?". Non-printable characters are defined by [isprint(3)|http://linux.die.net/man/3/isprint] according to the current locale.
> Default to {{-q}} behavior on terminal; otherwise, print raw characters. See the difference in these 2 command lines:
> * {{hadoop fs -ls /dir}}
> * {{hadoop fs -ls /dir | od -c}}
> In C, {{isatty(STDOUT_FILENO)}} is used to find out whether the output is a terminal. Since Java doesn't have {{isatty}}, I will use JNI to call C {{isatty()}} because the closest test {{System.console() == null}} does not work in some cases.
