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

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
