using find to clean /tmp of files older than 1 day 
       host.root-#-> find . -atime +1 -name '*' -exec rm -f {} \; 
or     host.root-#-> find /tmp -atime +1 -name '*' -exec rm -f {} \; 

     also:   find /usr/tmp -atime +1 -name '*' -exec rm -f {} \; 
     remove cores:   find / -name core -exec rm -f {} \; 

 using  find to compress overladen user directories 
     find . -type f -exec compress -f {} \; 

(and to undo it should they complain:)
     find . -type f -exec uncompress {} \; 
    
 examples from the HP-UX man pages 

 EXAMPLES
  Search the two directories /example and /new/example for files containing the 
  string Where are you and print the names of the files:
      find /example /new/example -exec grep -l 'Where are you' {} \;

  Remove all files named a.out or *.o that have not been accessed for a week:

       find / \( -name a.out -o -name '*.o' \) -atime +7 -exec rm {} \;

    Note that the spaces delimiting the escaped parentheses are required.

  Print the names of all files on this machine.  Avoid walking nfs directories 
  while still printing the nfs mount points:
            find / -fsonly hfs -print 

 Copy the entire file system to a disk mounted on /Disk, avoiding the recursive 
 copy problem.  Both commands are equivalent (note the use of -path instead of -name):

           cd /; find . ! -path ./Disk -only -print | cpio -pdxm /Disk
           cd /; find . -path ./Disk -prune -o -print | cpio -pdxm /Disk 

 Copy the root disk to a disk mounted on /Disk, skipping all mounted file systems 
 below /.  Note that -xdev does not cause / to be skipped, even though it is a mount 
 point.  This is because / is the starting point and -xdev only affects entries 
 below starting points.

           cd /;  find . -xdev -print | cpio -pdm /Disk 

   Change permissions on all regular files in a directory subtree to mode
   444, and permissions on all directories to 555:

         find  -type f -print | xargs chmod 444
           find  -type d -print | xargs chmod 555  

   Note that output from find was piped to xargs(1) instead of using the -exec 
   primary.  This is because when a large number of files or directories is to 
   be processed by a single command, the -exec primary spawns a separate process 
   for each file or directory, whereas xargs collects file names or directory 
   names into multiple arguments to a single chmod command, resulting in fewer
   processes and greater system efficiency.

 remove old core files 

 find core files with an access time over 4 days, then remove 
find . -atime +4 -name core -exec rm -f {} \;  



find / -atime +4 -name core -exec rm -f {} \;  



 note: find commands from / are often frowned upon by system owners

  use the . command or specify the path.  IN addition, if not run as root 

  you will run into permission problem errors.

 find core files, then remove 
find . -name core -exec rm -f {} \;  



find / -name core -exec rm -f {} \;  



 note: find commands from / are often frowned upon by system owners

  use the . command or specify the path.  IN addition, if not run as root 

  you will run into permission problem errors.

 find old files, then remove 
find . -atime +60 -exec rm -f {} \;  



 find large file, say 100,000 bytes,  not accessed for 7 days 
find /users -size +100000c -atime +7
