Calling BASH script from JAVA

Hi,

I am trying to call a bash script from a java file.

Code to call bash script will look like:

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("mybashfile.sh");

It is succesfully calling the bash file.

I am using simple rm commands in the script to remove files and directories and it is removing those correctly.

But, when i use sleep between the rm commands, files and directories are not getting removed.

I am new to Linux. Please tell me what should i do

alzabo::runtime::uniquerowcache

Alzabo::Runtime::UniqueRowCache(3pm)			User Contributed Perl Documentation		      Alzabo::Runtime::UniqueRowCache(3pm)

NAME

       Alzabo::Runtime::UniqueRowCache - Implements a row cache for Alzabo

SYNOPSIS

	 use Alzabo::Runtime::UniqueRowCache;

	 Alzabo::Runtime::UniqueRowCache->clear();

DESCRIPTION

       This is a very simple caching mechanism for "Alzabo::Runtime::Row" objects that tries to ensure that for there is never more than one row
       object in memory for a given database row.

       To use it, simply load it.

       It can be foiled through the use of "Storable" or other "deep magic" cloning code, like in the "Clone" module.

       The cache is a simple hash kept in memory.  If you use this module, you are responsible for clearing the cache as needed.  The only time it
       is cleared automatically is when a table update or delete is performed, in which case all cached rows for that table are cleared.

       In a persistent environment like mod_perl, you should clear the cache on a regular basis in order to prevent the cache from getting out of
       sync with the database.	A good way to do this is to clear it at the start of every request.

METHODS

       All methods provided are class methods.

       * clear
	   This clears the entire cache

       * clear_table( $table_object )
	   Given a table object, this method clears all the cached rows from that table.

       * row_in_cache( $table_name, $row_id )
	   Given a table name and a row id, as returned by the "Alzabo::Runtime::Row->id_as_string" method, this method returns the matching row
	   from the cache, if it exists.  Otherwise it returns undef.

       * delete_from_cache( $table_name, $row_id )
	   Given a table name and a row id, as returned by the "Alzabo::Runtime::Row->id_as_string" method, this method returns the matching row
	   from the cache.

       * write_to_cache( $row_object )
	   Given a row object, this method stores it in the cache.

AVOIDING THE CACHE

       If you want to not cache a row, then you can pass the "no_cache" parameter to any table or schema method that creates a new row object or a
       cursor, such as "Alzabo::Runtime::Table->insert()", "Alzabo::Runtime::Table->rows_where()".
