Ssh disturbs while loop

Hi all,

I have observed that ssh exits while loop.

#!/bin/ksh
 
typeset -i i
typeset -i size
set -A server =  " " "SERVER1" "SERVER2"
 
i=2
while [[ $i -le 3 ]]
do
   while read in_module
   do
     print $in_module
     size=`ssh ${server[$i]} ls -l $in_module 2>/dev/null | awk '{print $5}'`
   done < file1
   (( i=i+1 ))
done

The input file is

cat file1
RX.DBL
RX1.DBL

The output is

RX.DBL
RX.DBL

If I remove the ssh statement the output is fine. Any help?

TRy waiting:

while [[ $i -le 3 ]]
do
   while read in_module
   do
       print $in_module
       size=`ssh ${server[$i]} ls -l $in_module 2>/dev/null | awk '{print $5}'`
       wait
   done < file1
   (( i=i+1 ))
done

wait? Will not help.
The problem is that ssh sucks from the input, here file1 .
The simple solution is
ssh -n ... or </dev/null ssh ...

Great. Works perfect. Thank you very much.
