It does not display any header since you 1st grep for "Average" and so the header is lost. Maybe just add a printf somewhere in there with printing the header your own.
Also your chain of greps (crepes? ) can be done with one grep like for example:

I am the newest of newbies. Please excuse my ignorance. I have come across these two executables, sar and inedt, and am unfamiliar with their function. I have searched my limited resource library and would appreciate any insight available.

We have a script that uses
sar -u 1 10 | awk '/Average/ { print ( $2 + $3 ) }'
to get the CPU usage of a mutli engine machine. We think we are getting wrong information from the above string. We think it is adding up the total of the 12 engines and reporting back the total not the overall... (5 Replies)

Hi All,
I have come through this very nice tool which stores the week performance stats in solaris, but its only stores the stats for 8 in the morning to 5 in the evening. i want to extend the facility to work 24 hrs . Does anyone know how to do that?
Thanks in advance (1 Reply)
I am trying to set up sar on my AIX server. We have been running sar and getting reports on out Linux boxes in the past but would like to try to do the same in AIX. On my Linux i have a sar.sh that looks like this:

After adding these lines I have to get sar file.

Hi All,
I am trying to run sar on a Redhat server during a test I am performing for a couple of hours. I would like to get the sar metrics for every second (instead of the regularly set up 10 minute interval in the cron). What is the most efficient way to do this?
Thanks,

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
