problem while executing a script

[mumu <spamadore@xxxxxxxxx>]

Hello

I m using the following script to execute commands on a remote server
http://dev.libssh.org/browser/examples/exec.c

my problem is that when i wan't to execute this script

TMP=/tmp/onstat$$
SOFI_SPE=0
LIAI_SOFI=0
WALK=0
INFORMIX=0

INFORMIXDIR=/informix
export INFORMIXDIR

PATH=$PATH:$INFORMIXDIR/bin
export PATH

echo "[PROCESS WALKIMAGE]"

ps -ed|grep lt-inter > $TMP
if [ -s "$TMP" ] ; then echo "lt-inter=OK"
else echo "lt-inter=NOK"
WALK=2
fi

ps -ed|grep pltauth > $TMP
if [ -s "$TMP" ] ; then echo "pltauth=OK"
else echo "pltauth=NOK"
WALK=2
fi


ps -ed|grep pltbatch > $TMP
if [ -s "$TMP" ] ; then echo "pltbatch=OK"
else echo "pltbatch=NOK"
WALK=2
fi

data are truncated , i see only the result from the last command pltbatch=OK
with some letters

pltbatch=OK
KIMAGE

how can i get the good result,
note that i m a newbie, so a sample script is welcomed
this has been bothering me the whole day, so any answers is welcomed

thanks in advanced
