Problem using ssh inside script
Hi,
When runnin the following script it complte successfully with out any problem
Code:
#!/bin/sh
SERV="crm1"
for s in $SERV
do
export WebLogicSessions=`ssh psoft@$s "cd /software/psoft/scripts ; ./getweblogicsessions.sh crm1 8001 PIA | awk '{print $1}' `
echo "Checking number of WebLogicSessions on ${s}:  ${WebLogicSessions}"
done

./yoav_test.sh
Checking number of WebLogicSessions on crm1: 40

I changed a little bet the script to use arrays inseted on hardcoding , but this time i am asking to insert the Password in order to run in ssh .
Why ? the command to activate the SSH did not changed between those 2 scripts.
Thanks

Code:
vi yoav_test1.sh

#!/bin/sh
set -A web_host   $(awk '{print $1}' /software/oracle/PATCH/YoavWebList.lst)
set -A port_name  $(awk '{print $2}' /software/oracle/PATCH/YoavWebList.lst)
set -A pia_name   $(awk '{print $3}' /software/oracle/PATCH/YoavWebList.lst)

num_of_web_host=${#web_host[*]}
num_of_port_name=${#port_name[*]}
num_of_pia_name=${#pia_name[*]}

echo "Num of Hosts ${num_of_web_host}"

echo ${web_host}
echo ${port_name}
echo ${pia_name}

i=0
while [ $i -lt ${num_of_web_host} ]
do
  echo "wbe_host_name=${web_host[$i]}"
  --export WebLogicSessions=`ssh psoft@$s "cd /software/psoft/scripts ; ./getweblogicsessions.sh crm1 8001 PIA | awk '{print $1}' `
  export WebLogicSessions=`ssh psoft@${web_host[$i]} cd /software/psoft/scripts ; ./getweblogicsessions.sh ${web_host[$i]} ${port_name[$i]} ${port_name[$i]} | awk '{print $1}' `
  echo "Checking number of WebLogicSessions on ${web_host[$i]}:  ${WebLogicSessions}"
  (( i=i+1 ))
done
"yoav_test1.sh" 24L, 931C 

 ./yoav_test1.sh 
Num of Hosts 22
CRM1
8001

wbe_host_name=CRM1

NAME

       print - shell built-in function to output characters to the screen or window

SYNOPSIS

   ksh
       print [ -Rnprsu [n]] [arg...]

DESCRIPTION

   ksh
       The shell output mechanism. With no flags or with flag - or -, the arguments are printed on standard output as described by echo(1).

OPTIONS

       The following options are supported:

       -n	       suppresses new-line from being added to the output.

       -R

       -r	       (raw  mode) ignore the escape conventions of echo. The -R option will print all subsequent arguments and options other than
		       -n.

       -p	       causes the arguments to be written onto the pipe of the process spawned with |& instead of standard output.

       -s	       causes the arguments to be written onto the history file instead of standard output.

       -u [ n ]        flag can be used to specify a one digit file descriptor unit number n on which the output will be placed. The default is 1.

EXIT STATUS

       The following exit values are returned:

       0	Successful operation.

       >0	Output file is not open for writing.
