Samething works for me too when I just run the sar command.

I am guessing some how when reading the file they maybe changing
the file descriptor to another number other than stdout or stderr. Could that confuse sed?

I guess I will post this in an IBM specific forum to verify.

If anybody with an AIX box can try my above-mentioned example I would
apprciate it, this will verify if its the sar command. BTW, I am running aix
version 5.3

isag

ISAG(1) 						      System Activity Grapher							   ISAG(1)

NAME

       isag - Interactive System Activity Grapher

SYNOPSIS

       isag [-p datafiles_path] [-c config_file] [-ght gr_height] [-gwd gr_width]

DESCRIPTION

       The isag command graphically displays the system activity data stored in a binary data file by a previous sar run. The isag command invokes
       sar to extract the data to be plotted.

       The data are processed using sar command and slightly transformed to tabular format, and then this format is visualized using gnuplot pro-
       gram.

OPTIONS

       -p datafiles_path
	   Specify the pathname where are located the daily data files.  Default path is: /var/log/sysstat

       -c config_file
	   Specify the configuration file used by the isag command.  The contents of this file may depend on isag version number.  Default config
	   file is: $HOME/.isag.cfg.

       -ght gr_height
	   Specify the height of the chart area.  Default value is: 400.

       -gwd gr_width
	   Specify the width of the chart area.  Default value is: 720.

CONFIG FILE

       As mentioned above there is a config file. There are stored following values:

       last showed graph

       y limits for each kind of graph

       It seems useful, because new run doesn't need new settings to obtain same scale.

PREREQUSITIES

       Here is list of prerequsities including versioning and built-in features.

       Tcl/Tk Version 8.0 or newer.

       gnuplot
	      Gnuplot must have a tkcanvas display.
