Okay, so you are running this at the shell prompt, so this is a shell script. I think you will find that the packdisk has exited because it has no input. The next line y will then be execute (no used as input to the previous) and that command probably is unknown. Your showspace and scandisk may give output or exit, but your last command is yes and this is a recognised command. It is the yes command that is giving you all the output. Have a look at man yes for how it works.

I must admit I'm unaware of the early command format too, such as output over .... I assume that you are wanting to define the output file and overwrite an existing one, but this is not a way I recognise.

Oddly you have the command enable which is normally associated with printers. Are you trying to run this as input to some other program? If so you might need to:-

Code:

some_other_prog <<-EOF > /tmp/logfile 2>&1
output over /var/opt/Teradata/bteqdba/TAREAS_DBA.log
enable scriptmode
scope vproc all
showspace
packdisk
y
showspace
scandisk
yes
quit
EOF

The section between the red highlights is used as input to the calling some_other_prog

Please show us what you get from the following keyed at the command line:-

Code:

whence output packdisk scope showspace
for file in location_of_each_item_found_above
do
   printf "\n$file:-\n"
   head $file
done

alias | egrep "output|packdisk|scope|showspace"

There's just not enough to go on just yet.

Regards,
Robin

ppmquantall

ppmquantall(1)						      General Commands Manual						    ppmquantall(1)

NAME

       ppmquantall - run ppmquant on a bunch of files all at once, so they share a common colormap

SYNOPSIS

       ppmquantall [-ext extension] ncolors ppmfile ...

DESCRIPTION

       Takes a bunch of portable pixmap as input.  Chooses ncolors colors to best represent all of the images, maps the existing colors to the new
       ones, and overwrites the input files with the new quantized versions.

       If you don't want to overwrite your input files, use the -ext option.  The output files are then named the same as the input files, plus  a
       period and the extension text you specify.

       Verbose	explanation:  Let's  say  you've got a dozen pixmaps that you want to display on the screen all at the same time.  Your screen can
       only display 256 different colors, but the pixmaps have a total of a thousand or so different colors.  For a single pixmap you  solve  this
       problem	with  ppmquant;  this  script  solves  it for multiple pixmaps.  All it does is concatenate them together into one big pixmap, run
       ppmquant on that, and then split it up into little pixmaps again.

       (Note that another way to solve this problem is to pre-select a set of colors and then use ppmquant's -map option  to  separately  quantize
       each pixmap to that set.)
