Description

For example:

-bash-4.1$ hadoop fs -mkdir /user/hdfs
-bash-4.1$ hadoop fs -touchz /user/hdfs/dupfile
-bash-4.1$ hadoop fs -touchz /user/hdfs/dupfile^M
-bash-4.1$ hadoop fs -ls /user/hdfs
Found 2 items
rw-rr- 3 hdfs supergroup 0 2013-05-14 07:13 /user/hdfs/dupfile
rw-rr- 3 hdfs supergroup 0 2013-05-14 07:13 /user/hdfs/dupfile

By way of comparison, bash will print a '?' at the end of the file name, indicating there's a special character in the filename, which isn't perfect but at least gives an indication that there's more to the filename than just alphanumeric characters
