Hi Rveri:

Use 'printf' (see the manpages). You can read your exiting data using a shell, 'awk' or Perl script.

Ascertain the number of columns in any line read and issue an appropriate 'printf' statement.

Regards!

Use this awk script to get you started:

my.awk
--------------------
{
if (NF == 7) {s1 = ""} else {s1 = $1}
printf("%-10.10s ",s1)
i = 2
while (i < NF)
{
printf("%-10.10s ",$i)
++i
}
printf("-10.10s\n",$NF)
}
--------------------------

Use it like this:

sar -d 2 5 | awk -f my.awk
or
awk -f my.awk myinputfile

This is not meant to be a finished script but it will be close. A better script would build the awk script "on the fly" or a heredocs so that the external awk script is not needed.
