question about rsh and read

[dell9]

this shell works,it read each line of the file and output
#!bin/bash

while read line
do
echo $line
done < inputfile
---------------------------
but when i add an rsh command within the loop, shell only reads the first line of the inputfile and stops.
#!bin/bash
while read line
do
echo $line
rsh 10.188.15.24 ls > fff
done < inputfile

anybody know what's wrong with that?and how should i fix it?
thanks

Hi,

Is your rsh configured to connect without password to 10.188.15.24 host ?
If no, mybe this is what is stopping your loop waiting for a password to connect.

Have a look at the -n option in your rsh man page.

Hope This Helps, PH.

One way is to run rsh with input redirected from /dev/null to keep it from gobbling up your local input data

while read line
do
rsh wherever whatever [red]</dev/null[/red] >outfile
done <infile

rsh -n also works in the same manner.

HTH,
