Allen Wittenauer commented on HADOOP-10901:
-------------------------------------------

Nope.  This is about fixing shell code that currently looks like this:

{code}
  lsSnapshottableDir)
{code}

to look like this:

{code}
  ls[Ss]napshottable[Dd]ir)
{code}

so that a user doesn't have to hit their shift key to type

{code}
hdfs lsSnapshottableDir
{code}

and instead can type

{code}
hdfs lssnapshottabledir
{code}

like all sane Unix commands.

> provide un-camelCased versions of shell commands

> There is a heavy disposition to do camelCase subcommands because it reflects 
> what is in the Java code.  However, it is very counter to the shell.  We 
> should replace the case options to accept both the camelCase and the fully 
> lowercase options.
