view disc-usage by owner

[alexandru]

Hi,

I have a dir with loads of files and sub-directories, owned by different users and
I wanted to generate a list of the summarized file-sizes by owner.

I tried something like:

find . -print0 -type f -user someuser > tmp
du -sh --files0-from=tmp

but I get just a bunch of crap.

How can I do this?

I'd use a combination of ls -l and awk. For example

 ls -l directory|awk '$3~name{total=total+$5};END {print total}'

will print out the total disk space for files owned by name in directory. You can tweak the program so that it prints out the data you want.

Works perfectly, thanks!

tweaked it to something like:

ls -lR /somedir/ | awk '$3~"user1"{total1=total1+$5} $3~"user2"{total2=total2+$5};END {print "user1: " total1 "\nuser2: " total2 }'

Wrap your command in a for loop and cater for all names present:

for name in $(ls -l /somedir | awk '{print $3}' | sort -u)
do
    echo $name   # (your counting command here)
done
