Hi all
many thanks for all your suggestions
but none of the commands is able to give the size of only the first line.
the following cmds
Code:
awk -F" " 'NR=1{print $1}' test.log
and 
sed -n -e "s/^ *\([^ ]*\) *.*_error.*/\1/p;"  test.log
and
 ls -l `awk -F" " 'NR == 1 { print $2; exit }' test.log` | awk '{ print 1 }'

gives the first column for all the files...but i only need for the first one Smilie

any help is appreciated
Thanks
Kiran
