Find total size for some files?


I'm newbie to Unix. I'd like to count the total size of those files in my directory by date. For example, files on this period 05/01/08 - 05/31/08. If possible can we count by byte instead of kb.

if I use $ du - ks , it will add up all files in the dir.

You can use something like this to find the size (in bytes) of all files in the current directory modified within last 30 days:

find . -type f -mtime -30 -exec ls -l {} \; | awk '{ s+=$5 } END { print s }'

I really don't know how we could specify a begin/end date range.

can we grep the filenames and sizes for this range (05/01/08 - 05/31/08) and output them to a file?

touch two files - one with the start and the other with the end time you need.
touch -t 200805010000.01 dummy1
touch -t 200805312359.59 dummy2
find /path  \( ! -newer dummy1 -a newer dummy1 \) -type f -exec ls -l {} \;

apply Franklin's code or whatever to the output

Very smart solution jim! There's always something to learn.

I have to write this down: for the future, you'll never know Smilie

I didn't see dummy2 in FIND command. Instead of 2 dummy1s.

But, I got this error!

find: bad option newer
find: path-list predicate-list
