Problems with hourly removal in cron
In my cron job on one system I have log files removed older than 3 days, like so:
Code:
find /u01/arch/PRD8 -mtime +3 -a -name "*.log" -exec rm {} \;

On another system I would like to check and remove anything older than 2 hours.

Any help would be greatly appreciated Smilie

find's -mtime measures in days, as you surely know. What other options are availble depends on what your system is.

---------- Post updated at 12:30 PM ---------- Previous update was at 12:26 PM ----------

A solution from a thread currently immediately below this one is as follows:
Code:
#!/bin/sh

[ -f /path/to/Flag_File ] &&
  find /where/files/are/ ! -newer Flag_File |
  while read mFile
  do
    mv "${mFile}" New_Directory
  done

touch /path/to/Flag_File

The very first time it runs, it removes nothing, but it creates a file to refer to. Next time, it moves everything older than the file then updates the timestamp. So, run it every 10 minute and it moves files older than 10 minutes. Run it every 3 hours and it moves files older than 3 hours. etc.

Thanks.

Adapting the above script may do what you want, put it in a crontab that runs it every two hours, like

Code:
* 0,2,4,6,8,10,12,14,16,18,20,22 * * * /path/to/script.sh

Then within the script I would have something like:
Code:
find /u01/arch/PRD8 -a -name "*.log" -exec rm {} \;

Is this correct?

Then within the script you'd have the script I already posted,
Code:
#!/bin/sh

[ -f /path/to/Flag_File ] &&
  find /where/files/are/ ! -newer Flag_File |
  while read mFile
  do
    mv "${mFile}" New_Directory
  done

touch /path/to/Flag_File

Where /path/to/Flag_File is wherever you want to keep the flag file, and /where/files/are is where you want to search in, and mv "${mFile}" New_Directory is changed to whatever you want to do to old files.

There a couple of us that watch the systems and I would like to keep the scripts pretty standard so everyone knows what's going on. Would the contents of the script like I have it now work with the cron set to run every two hours?
Code:
find /path/to/file -a -name "*.log" -exec rm {} \;
