[SOLVED] bash script to ssh and run commands

Issue

I want to ssh to a node and run a command there and then exit. This is repeated for all nods. The script is fairly simple

#!/bin/bash
NODES="compute-0-0 compute-0-1 compute-0-2 compute-0-3"
for i in $NODES
do
   ssh $i
   ls -l /share/apps 
   rpm -ivh /share/apps/file.rpm
   exit
done

But the problem is that, after the ssh, the ls -l command is missed. Therefore, the command prompt waits for an input!

Any way to fix that?

UPDATE:

I modified the loop body as

ssh $i <<END
 ls -l /share/apps
 exit
END

But I get

./lst.sh: line 9: warning: here-document at line 5 delimited by end-of-file (wanted `END')
./lst.sh: line 10: syntax error: unexpected end of file

Solution

Try this

    #!/bin/bash
    NODES="compute-0-0 compute-0-1 compute-0-2 compute-0-3"
    for i in $NODES
    do
       ssh $i "ls -l /share/apps;rpm -ivh /share/apps/file.rpm;exit;"
    done
