Shell Programming and Scripting

Hi,

From one of the unix servers i want execute an rsh command to 5 different servers.
i want to go to these servers execute a command and come back.
i have a main program which calls a function, where in i use the rsh command.
The server name is passed as a parameter to teh function.
it is working fine for the first server, after that it is not executing rsh for the other servers.
the structure is

fun () {
rsh $1
}

while read line
do
fun $line
done < server_name.txt

i tried with ssh also but the same problem persists.

Advance Thanks
Praphul

can you post the complete rsh line in the function? based on the info you've give so far, my guess is your rsh line is not terminating correctly so your function cannot go to the next iteration of the loop ...

sudo rsh <server name> cat /a/b/c/d |grep -v '*'|grep -v ' '|grep -v '#'|grep 8.1.7|cut -d ':' -f1>> ~/test

Thanks

can you run the rsh lines manually on the command line for each of the other servers? if not, your issue may be that the account you're using to do the rsh to the other servers is not setup properly ... check $HOME/.rhosts and/or $HOME/.ssh to make sure they are the same on all your listed servers for the account in question ...
