Hi, Could you give an example of how to run this. I am new to perl. Also how would you incorporate the Filecache in this example. I want to split a file based on the first column and save in file with the name as the name in the first column field without the quotations. ex. data: 
"1", "This" , "is" , "test", "data"
"1", "This" , "is" , "test", "data"
"2", "This" , "is" , "test", "data"
"1", "This" , "is" , "test", "data"
"1", "This" , "is" , "test", "data"
"4", "This" , "is" , "test", "data"
"2", "This" , "is" , "test", "data"
"3", "This" , "is" , "test", "data"

would create four files named 1,2,3,4 with the data in it. 
file 1: 
"1", "This" , "is" , "test", "data"
"1", "This" , "is" , "test", "data"
"1", "This" , "is" , "test", "data"
"1", "This" , "is" , "test", "data"

file 2:
"2", "This" , "is" , "test", "data"
"2", "This" , "is" , "test", "data"

file 3:
"3", "This" , "is" , "test", "data"

file 4:
"4", "This" , "is" , "test", "data"

It is large file so I need to use the Filecache Thanks For any help
