Finding total size of files owned by a particular user

Syntax:

# find <pathname> -user <username> -ls | awk '{sum += $8} END {printf "Total size: %8.4f MB\n", sum/1024/1024}'

Example:

[root@nasllm01-ih ~]# find /nasllm-ih -user rram -ls | awk '{sum += $8} END {printf "Total size: %8.4f MB\n", sum/1024/1024}'                   

Total size: 958.7282 MB

[root@nasllm01-ih ~]#

Validation:

Here I have created a folder /root/ashok consists files owned by user “adevaraju” of total size: 160 MB.

[root@oralsb11-new ~]# ls -lRh /root/ashok

PS: Please note there is a difference in AWK statement. The Field separator value  will be one count more for Domain users since it has an extra space in-between (domain users).
