Looks like it's all the same. There should be a different number of total bytes per year


> find . -type f -ls | nawk '{arr[$8] += $7} END {for (i in arr) prin
tf("%s -> [%d]\n", i, arr[i])}'

Apr -> [2147483647]
Jun -> [2147483647]
5 -> [0]
25 -> [0]
Oct -> [2147483647]
Sep -> [2147483647]
Nov -> [2147483647]
Mar -> [2147483647]
May -> [2147483647]
Dec -> [2147483647]
Jan -> [2147483647]
Aug -> [2147483647]
Jul -> [2147483647]
Feb -> [2147483647]

pls start using code tags.

Code:
find . -type f -follow -ls | nawk -v yearNOW=$(date +%Y) '{year= (index($10, ":")) ? yearNOW : $10; arr[year] += $7} END {for (i in arr) printf("%s -> [%d]\n", i, arr[i])}'

I ran your code and received the results by year. It doesn't look correct.
I see years 2004 - 2006 have the same value. This couldn't be correct.

find . -type f -ls | nawk -v yearNOW=$(date +%Y) '{year= (index($1
, ":")) ? yearNOW : $10; arr[year] += $7} END {for (i in arr) printf("%s -> [%d
\n", i, arr[i])}'

2003 -> [1736530393]
2004 -> [2147483647]
2005 -> [2147483647]
2006 -> [2147483647]

once again..... if you need to post code, surround the code with the 'code' tag - see my previous link on how to use the tags.

if you're directing your question towards a given poster, PLS do quote the original post you're replying to OR post the name you're directing your reply to.

as for your output..... what OS are you on?
pls post a sample output of the 'find . -type f -ls' command to see the format of your 'find'.

the above solution worked fine under Sun/Solaris.

here's a slightly modified script to follow the 'symbolic links' for 'find':
Code:
find . -type f -follow -ls | nawk -v yearNOW=$(date +%Y) '{year= (index($10, ":")) ? yearNOW : $10; arr[year] += $7} END {for (i in arr) printf("%s -> [%d]\n", i, arr[i])}'

Alternative in Python:
Code:
#!/usr/bin/python

import os,stat,time
year = {} #store year calc
for files in os.listdir("."):
 	if not os.path.isfile(files):    continue
 	properties = os.stat(files)
 	size, t = properties[6], properties[stat.ST_MTIME] #get file size, modified time
 	yr = time.ctime(t)[-4:] #get year
 	if not year.has_key(yr): year[yr] = 0
 	year[yr] += size	

for i,j in year.iteritems():
     print "Year: %s, Size: %s" %(i,j)
