You are on Linux:
Code:
stat -c %s *2010-05-30.txt  | awk '{sum += $1} END{print "total: ", sum}'

Code:
echo "scale=2;$sum/1024^3" | bc

where $sum is variable containing size in bytes

Hi,

Probably you can try these steps

1) Go into the directory where you have all these files.

2) ls -l *2010-05-30.txt | awk ' { sum = sum + $5 } END {print "Total Size = "(sum/1024)/1024 "GB" }'

3) You will get the desired results.

Regards
Naree
