Hi ,

I want to find files that are not modified since 1 year and 6 months.
could any one give the command as to how to find out?. I try some of the find options but that doesnot give me the answer for my requirement exactly.

Thanks

find <dir> -mtime +##

1.6 years * 365 = 534

find ./ -mtime +534

find ./ -mtime +534 | du -sh .

Thanks

you will want something like:

Code:

find ./ -mtime +534 -print0 | du -ch

which doesnt work in ubuntu.

edit: out of curiosity, i was able to search and find this for ubuntu:

Code:

find . -printf "%s\n" | awk '{t+=$1}END{print t}'

If you did that you would have to then add all the sizes together to get a grand total. ((< not aimed at szboardstretcher. His answer is also correct)) Here is a way using awk:

find . -mtime +534 -ls |awk '{total += $7} END {print total}'
This gives the result in bytes
For KB use:
find . -mtime +534 -ls |awk '{total += $7} END {print total/1024}'
For MB use:
find . -mtime +534 -ls |awk '{total += $7} END {print total/1024/1024}'
And so on...

Code:

du -hcs $(find ./ -mtime +534)

or

Code:

find ./ -mtime +534 -exec du -hcs {} +

Correct. I didnt mention that the first example will give the size of each file, and the second will add up all the files as bmrtin suggests here.

Thanks for reply!!

I ran the following command to find files that are not modified since 1 year and 6 months

find . -mtime +534 -ls |awk '{total += $7} END {print total/1024/1024}'

and got the following output

2.37775e+06

Is it 2.3 TB size?

Thanks
