cleaner.sh 

This script cleans directories.  It is useful for backup 
and log file directories, when you want to delete older files. 

USAGE:  cleaner.sh [options]

OPTIONS:
   -h      Show this message
   -q      This script defaults to verbose, use -q to turn off messages 
           (Useful when using the cleaner.sh in automated scripts).
   -s      A search string to limit file deletion, defaults to '*' (All files).
   -m      The minimum number of files required in the directory (Files 
           to be maintained), defaults to 5.
   -d      The directory to clean, defaults to the current directory.
   
EXAMPLES: 
   In the current directory, delete everything but the 5 most recently touched 
   files: 
     cleaner.sh
         Same as:
     cleaner.sh -s * -m 5 -d .
   In the /home/myUser directory, delete all files including text "test", except 
   the most recent:
     cleaner.sh -s test -m 1 -d /home/myUser
         Don't ask for any confirmation:
     cleaner.sh -s test -m 1 -d /home/myUser -q
