calculate size of some files

big123456 · #1 (**permalink**) 07-21-2005

Hi,
1-I want to calculate the size of all files which are generated during last month in a directory. How can I do that ?
Of cours, I find them by :
$ls -l | grep jun
but how to calculate the sum of their size ?
2- the same but for all files generated last month and before that.
many thanks before.

If you combine the following scripts you should get what you want:

http://www.pixelbeat.org/scripts/find_mm_yyyy
http://www.pixelbeat.org/scripts/add

The following might work straight off?

find_mm_yyyy 06 2005 -printf "%s\n" | add

thank you.
I want to find all from may 2005
For the first I have this problem :
$altest
Usage: altest MM YYYY
$altest 05 2005
date: illegal option -- -
date: illegal option -- t
date: illegal option -- c

How should I enter the date then ?
Thanks.

the problem is that the script is using GNU-specific 'date' options. If you don't have GNU 'date' - you're out of luck with this script.

This is not bullet-proof, but.... [Solaris 9 stock 'ls']

Code:

ls -lrt | nawk '$6 == "Jun" {sum+=$5} END{print sum}'

If you need a better solution, you would need to use 'find' with '-newer' options. You might wanna search FAQs for more leads/options.

Code:

sum=0 
for filesize in  $(  ls -la |grep $(date -d '1 month ago' +%Y-%m )|awk '{print $5}'  ) 
do 
   let sum=sum+filesize 
done 
echo sum $sum

Again - this is GNU-based AND you're using grep AND awk all in one - in most cases it's considered UUOG

thank you. but it gives me :
date: illegal option -- d
usage: date [-u] mmddHHMM[[cc]yy][.SS]
date [-u] [+format]
date -a [-]sss[.fff]
Any way how can I format date to have just last month ? Thank you.
