Thanks for your reply. I've worked on this a fair bit yesterday and got a lot further than I thought I would.

I am using the find command to look through all files and directories, look at the modified time (-mtime) and report back all files that are modified between set time frames ... so last week, 1 to 4 weeks ago, 1 to 6 months ago etc ... all the way up to over a year ago.

Code:
find . -path './.snapshot' -prune -o  -type f -mtime -8 -ls

I have then put piped the output to awk to sum the number of bytes and number of files:
Code:
 | awk '{bytes += $7; count++} END print bytes, count}'

I am running this as 2 loops - so that I get all the subdirectories in the top level as supplied at the command line.

I am passing all output through several echo commands to output in html format so I can put the output in a table.

Sample output so far:

HTML Code:
<table width="960" border="1" bordercolor="gray" align="center" cellpadding="0" cellspacing="0">
<tr align="center"><td align="left" width="160">foobar</td>
<td colspan="2" width="160">0 - 7 days</td>
<td colspan="2" width="160">1 - 4 weeks</td>
<td colspan="2" width="160">1 - 6 months</td>
<td colspan="2" width="160">7 - 12 months</td>
<td colspan="2" width="135">1 year +<td></tr>
<tr align="right"><td align="right">/basecase</td>
<td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>187307</td><td>2</td> <td>&nbsp;</td><td>&nbsp;</td> <td>160477762</td><td>132</td> </tr>
<tr align="right"><td align="right">/cbabble</td>
<td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>120476297</td><td>82</td> <td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> </tr>
<tr align="right"><td align="right">/hi_STOIIP</td>
<td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>5561429</td><td>15</td> </tr>
<tr align="right"><td align="right">/libra</td>
<td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>30312</td><td>18</td> </tr>
<tr align="right"><td align="right">/lowestcase</td>
<td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>17828811</td><td>26</td> </tr>
<tr align="right"><td align="right">/region</td>
<td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>108363878</td><td>105</td> </tr>
<tr align="right"><td align="right">/with_XYZ</td>
<td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>&nbsp;</td><td>&nbsp;</td> <td>35384975</td><td>43</td> </tr>
</table>
I will have a table as above for each directory in the file path supplied at the command line - one table after another.

I allows me to see which directories have not been modified for a long time - so in the above example I could possible archive off the last 5 directories as they have not been modified in the past year.

Does that makes sense?

I wonder if my find command is good enough?
Is -mtime reliable?
Should I use -atime?

(Sorry for the wide page!)
