Shell Programming and Scripting

I am using the fallowing script. this script seems to work fine except the file has data I do not wish to have. Is there away to omit that data. I will first provide the scrip and then a sample of the data the way it looks and then a sample of how I would like the data to look. Thanks for any help. I am very new to UNIX and scripting as well.

This is the script I am using

#!/bash
sar -u 1 1 >>/home/scripts/cpu.$(date +"%Y.%m.%d").csv
swapinfo >>/home/scripts/memory.$(date +"%Y.%m.%d").csv


This is how the file looks now
HP-UX commnms B.11.11 U 9000/800 07/07/09

08:35:00 %usr %sys %wio %idle
08:35:01 65 35 0 0

HP-UX commnms B.11.11 U 9000/800 07/07/09

08:40:00 %usr %sys %wio %idle
08:40:01 58 42 0 0

HP-UX commnms B.11.11 U 9000/800 07/07/09

08:45:00 %usr %sys %wio %idle
08:45:01 24 24 51 1

Here is how I would like the file to look
HP-UX commnms B.11.11 U 9000/800 07/07/09

08:35:00 %usr %sys %wio %idle
08:35:01 65 35 0 0
08:40:01 58 42 0 0
08:45:01 24 24 51 1

I would then like to import the file in to Microsoft excel for some data manipulation. I suppose I could just email the file to me then copy and past it into excel.

This is on a HPUX box

Add these following lines to your script and try:

grep HP-UX /home/scripts/memory.*.csv | uniq
grep '%idle' /home/scripts/memory.*.csv| head -1
grep -v ^$ /home/scripts/memory.*.csv| grep -v HP-UX | grep -v '%idle'

Dose the placement of these lines matter? Do they go before or after the sar command?

Sorry for the late reply. These lines go after the swapinfo command.
