Print file count owned by a given user

How to print the number of files owned by every user in a given directory?
So far I am printing user name and disk size. However I want to report out the output of "find $dirname -user <user_name>| wc -l" and print that as a third field in the below printf

find $dirname -user <user_name>| wc -l

set dirname = "a/b/c"

find $dirname -printf "%u %sn"

I have a feeling you want to do something like this :

find $dirname -printf "%u %sn"
| awk '{s[$1]+=$2;c[$1]++}END{for(u in s) print u,s[u],c[u]}


This will print a list of users with total accumulated file-size and the total amount of files.

Exactly what I was trying to get at! Did a lot of circus and foreach loops with find <dir_name> -user <user_name | wc -l followed by saving the contents into an array. Even then was lost on how to type the array as a 3rd column! Thank you :)

You can use stat id and awk to do something along these lines:

stat

id

awk

$ cd /var
$ stat -f '%u%t%N' * | awk -F$"t" '{fn[$1][$2]}
END{for (u in fn){
system("id -nu " u)
for (e in fn[u]) print "t" e
}}'


Prints

_jabber
jabberd
root
log
rpc
netboot
lib
db
agentx
run
mail
folders
vm
backups
spool
tmp
install
audit
root
empty
yp
msgs
_mobileasset
ma
daemon
rwho
at
_networkd
networkd


As written, it does not support file names with t in them. Not a terribly hard fix (just concatenate the fields greater than $2 joined by t), but you get the idea.

t

t

Should this not be stat -c (man stat states: _ The valid format sequences for files (without --file-system):_, i.e. the format specifiers don't work with -f)

stat -c

man stat

-f

Since stat is not POSIX, it may vary by system. On BSD / OS X, there is no -c command line switch for stat. Nor is there a -printf option to find so this is an area varies. On Linux, find with printf properly formatted is likely the best bet or stat with the translated switches.

Thanks that's an interesting way to do it! I was able to get it work
