##
## PURPOSE: Creates a size-sorted * /data * sub-directory *   listing by
##          extracting lines from a weekly-created file like
##
##                  ${REPORTDIR}/spac_data_dirs_siz.lis  
##               or ${REPORTDIR}/spac_apps_dirs_siz.lis  
##
##                  where REPORTDIR="/usr/people/ideasadm/cleandir"
##
##          The extract is done in either of two ways
##              1) specifying a number of directory levels to show (1,2,3,4)
##              2) specifying a key-string to search for.  Examples:
##                    subs,  ideas, shared,  datamgmt,  flowmaster, etc. 
##
##    NOTE:
##          The /data & /apps subdir report files are created by
##          the ideasadm crontab script
##
##               creat_datadirsiz_lists   in /apps/ideas/cron
##
##          on 'engprd00'.
##                           See 'crontab -l' on engprd00, as ideasadm.
##                            See /apps/ideas/cron/READMEcrontab_ideas
##                        and /apps/ideas/cron/zREADMEcrontab_ideas.OLD97jul14
