calculate total size

nicksrulz · 04-05-2012, 07:10 AM

Was just wondering if anyone knows a script that can be used to find total size of all the files of a user's disk quota in Linux.

Any suggestions?

that is not a script but a single command: du (disk usage). Just look at the man page.

uhelp · 04-05-2012, 07:46 AM

repquota -u YourUser

@pan64
that might be useful if one is only interested in the total size of the users home dir.
But does not report the total size of all files.
There could be much more files in dirs not belonging to the users home.
Think of /temp or alike

Thanks!!!! pan64 and uhelp

#!/bin/bash

total_size=0

for file in * ; do
file_size=$( ls -ld ${file} | awk '{print $3 }' )
echo "${file_size} ${file}"
((total_size=total_size+file_size))
done

echo "------------"
echo "Total size: ${total_size}"

This is what i have done, but it give me sizes of all the files.... i want to print size used by paticular users.. but m not gettng it

I am not sure about the script as I am not so good with it but the same can be done through du

Code:

# du -sch /home/deepak/*
4.0K    /home/deepak/Desktop
4.0K    /home/deepak/Documents
4.0K    /home/deepak/Downloads
112K    /home/deepak/Maildir
4.0K    /home/deepak/Music
4.0K    /home/deepak/Pictures
4.0K    /home/deepak/Public
4.0K    /home/deepak/Templates
4.0K    /home/deepak/Videos
144K    total

Thanks Deepak!!! your command prints the size of each files and give total size... But i want to print total size used by a paticular user in a directory.... Any suggestions

You almost made it....

Code:

find <dir> -type f -user <user> -exec ls -l {} \; | awk ' { a += $5 } END { print a } '

you can run this command

Code:

#find / -type f -user $USER -exec du -sch {} \;

you can try different switch option with du

you can copy the o/p to some file as well for refrence

Code:

#find / -type f -user $USER -exec du -sch {} > size.txt \;

and another variant:

Code:

UsedSpace=$( ( find / -user username | du -s ) 2>/dev/null )
echo ${UsedSpace%% *}

Outputs just the amount of Bytes.
"du -sh" will output it human readable.
