UNIX: Find size for a list of files

[Guest_imported]

I am trying to get the total size of list of files in a directory.

We are trying to get the growth rate of a directory in terms of size. Specifically <Wild> Charactered files.

I use du -sk to find the size. But I am a bit confused about, how to get the total size of files like say COM_ABC_?_20010101.* in a directory.

Files in a directory

COM_ABC_1_20010101.txt
COM_ABC_2_20010101.txt
COM_ABC_3_20010101.txt
COM_ABC_4_20010101.txt
COM_ABC_5_20010101.txt
COM_123_1_20010101.txt
COM_XYZ_1_20010101.lst
...

I want the total size of the COM_ABC_?_20010101.* files from the current directory.

I have written a shell to do this, but the total is incremental.

Is there any ready-to-use script for this ?

Thanks in advance.

Hi UKID,

You can use awk for this purpose. eg

$cd <your dir>
$ls -l | awk '/COM_ABC_/ && /_20010101/ {sum+=$5} END{print sum}'
xxxxxx -> The sum of all files whose name matches the criteria '/COM_ABC_/ && /_20010101/'

You can build on the string matching part (ie /COM_ABC_/ && /_20010101/ ) to suit your need.
Hope this helps you.
