Hi John,

The closest you got is bin/hadoop dfs -<unix-like-command>. For example, to
list all files in a directory named foodir, one would do

bin/hadoop dfs -ls /foodir.

Similarly, to 'cat' a file one would do

bin/hadoop dfs -cat /foordir/filename

This is a non-interactive shell and the source code is in
src/java/org/apache/hadoop/dfs/DFSShell.java

Hope this helps,
dhruba

Is there a shell someone has written or writing to hadoop? e.g. a simple
unix shell that executes file commands to a HDFS such as, ls, rm, cp ...?

Thanks
