Thanks Jacoden...
actually my reqirement is not just to display those files with zero size but to check if the error log file is of size zero .
pls note that 190_GSTV_HUX_003QISCGSK026_errorXXXXXX.log(Here XXXXXX changes everytime i run the script..it gives the date time)
so i need to check for the error log file size is zero or not among the following:
16 190_GSTV_HUX_003QISCGSK026_messageXXXXX.log
21 190_GSTV_HUX_003QISCGSK026_activityXXXXX.log
10 190_GSTV_HUX_003QISCGSK026_errorXXXXX.log
The above files can b in any order.....

is there any cmd as such which suits my need

Thanks in advance

Let me get this straight. You want all *error*.log files of zero size. Right ?
Code:
sed -n -e "/^ *0 .*_error.*/p" /home/user/temp.log

Thanks vino
the cmd which u suggested is listing all the error files of size 0..
but i want to check for the latest error log file size Smilie

presently i am able to display only first 3 files in test.log by using
head -3 test.log
from these 3 files i need to get the error log file size and write a condition based on its size..........


BTW what do u mean by code tags?where can i find them Smilie
many thanks for your suggestions Smilie
