Quicker way to find library and file size

Richard Nichols' Using Disktasks tip is good. But if you have a large system, the run collect disk space information job can run for hours! The library and file sizes are only good for the day the information was collected. If you want to know library and file size in a jiffy my tip is to do:

DSPLIB LIB(*****) OUTPUT(*PRINT) 

Here is what your spool file looks like:

                        Display Spooled File 
                  Display Library 
  Library . . . . . . . . . . . . . :  ***** 
  Type  . . . . . . . . . . . . . . :   PROD 
  Number of objects . . . . . . . . :            3 
  ASP . . . . . . . . . . . . . . . :    1 
  Create authority  . . . . . . . . :   *SYSVAL 
  Text description  . . . . . . . . :   ************* 
    Object      Type      Attribute        Size  Description 
    ***          *FILE     PF                   2945024 
    ***          *FILE     PF                   11681792 
    ***          *FILE     PF                   83824640 
                        Total size :          98648064 
                      * * * * *   E N D   O F   L I S T I N G   * * * * * 

Hope this tip makes someone's life easier.
