RE:backup files older then 24hrs to a new directory .

How do you move (mv) files to a backup directory from a particular directory when the files are
older the 24hrs copied from a batch script run every 24 hrs.
Would you use find or some kind of timestamp.timestamp="$(date +'%m%d%I%M')"

try find maybe like this: -mtime +1 means older than one day (24 hours)

find /particular/directory -mtime +1  | \
  while read file
  do
       b=`basename "$file"`
       mv $file /path/to/new/directory/"$b"
  done

Jim, I believe there is some confusion regarding the mtime parameter. +0 stands for older than one day, +1 would stand for older than 2 days. Check this out:

Note that the file testfile shows up on using +0 and not on using +1. Check Perderabo's last post in this thread.
