Summation of file sizes in directory

[Harishs]

Hi ,
$ du -sk * ,it gives size of individual files in k bytes.

I want to get a summation of size of all files in directory ,could you please tell the command syntax to be used.

Thanks in anticipation.

Hi,
awk will help to sum the field.

du -sk * | awk '{ x += $1 } ;END { print "total bytes: " x }'

This should help you....

Have fun!!!!!

# du -ks .
for your current directory or
# du -ks directory_name
for a specific directory.

Hey

only "du -sk" without the '*' will show you the size including the subdirectories

Harish,
as you have allocated 8 points to Senthils response there is room for improvement.

Although Senthils answer sums up the entries via du the result is in KB not bytes.

Also in your original spec you said files, but the current answer includes directories.

So, if you want the 'perfect' answer please provide more info on exactly what you want to sum up. Files only, current directory (with/without subdirectories), local file system only ....?

Peter ,

In this case it was only files in directory.

It will be helpful if you can guide for sub directories as well.

Found this in my personal bin directory. I didn't write it, origin unknown. Works well though:

du -sk $* | \
awk '{i = i + $1; print $0;}
END {printf("---------------------\n%d KBytes\n", i);}'

Hi Harish,
I use the attached dsr.ksh script to gather info about dir spaces/file.

TIMTOWTDI,
but this should sum up sizes of files beneath a certain directory, remaining on the same filesystem (otherwise omit the -xdev).
e.g. for my /opt (chose any appealing start dir, also conversion to K, M, G or whatever ad lib)

# find /opt -xdev -type f|xargs ll|awk '$5>0{s+=$5};END{printf"%10.2f MB\n",s/2^20}'
1230.96 MB
