Shell Programming and Scripting

Hi,

I am compete linux noob, but have managed to setup my Thecus N5500 to rsync to my N5200Pro to do automatic backups each night.

The rsync script also moves any files deleted from the N5500 (and previously backed up to the N5200) to a _deleted folder on the N5200 so I can keep them for 30 days before removing them.

This is where I have run into a problem....

I have the following script that I run on the N5200;

Code:

#!/bin/bash
## This script will delete files older than 30 days from the deleted backups
## generated by nas_backup.sh on NAS1
find /raid0/data/nas_backup/media_deleted/* -mtime +30 -exec rm -f '{}' \;

The problem is I'm getting errors like these when I run the script;

I don't know if it's any help, but I did have to enclose the {} in quotes '{}' otherwise I got issues with spaces in the directory names as well, which there seems to be great debate in other threads if this is required of not.


I'm not sure what release/version on linux is on the thecus N5200 but I did get this from the box;
if it's any help.



Can anybody suggest how to fix this please?

Thanks
Richard

Code:

find /raid0/data/nas_backup/media_deleted -mtime +30 -exec /bin/rm -f {} +

And please refrain from wrongly thinking {} need to be quoted ...

Thanks for the quick response, the above code gives this error;

And this code

Code:

find /raid0/data/nas_backup/media_deleted -mtime +30 -exec /bin/rm -f {} + \;

gives the same error
Cheers

What find version are you using ? It looks like it doesn't know the posix "+" exec delimiter. It looks too it used "sh -c" to run its exec command, which is quite unexpected.
Anyway, try this:

Code:

find /raid0/data/nas_backup/media_deleted -mtime +30 -type f -exec /bin/rm -f {} \;

This gives the same token error I'm afraid.

I'm calling the script with "sh delete30days.sh", I assume this is the correct way to call it?

How do I get the FIND version? find -? gives this;

Interesting, so you aren't really using find but a subset of it provided by busybox. BusyBox - Wikipedia, the free encyclopedia

Assuming your system has the "line" command, you might try this:

Code:

find /raid0/data/nas_backup/media_deleted -mtime +30 -type f -print > /tmp/toRemove
while a=$(line)
do
   rm -f "$a"
done < /tmp/toRemove

Well the toRemove file looks like it's correct with a list of paths/files, but I'm getting an error;
So I guess that answers that question - no "line" command.

Here's what I have in /bin/, can I install a line command or an updated find somehow?
