Question

I need to run a script remotely. I am using the following shell script

    for server in $servers
     do
     LOCAL_VAR=<some_value>
     ssh $server <<EOF
      command1 $LOCAL_VAR
      command2..
      ..
      exit
      EOF
    done

bash shows unexpected end of file syntax error. The rest of the code works fine if I remove this block. Can you please tell me the correct way of executing a script remotely.

Answer 1

If you want to put indentation like that in your here-doc, you should add a - like the following code :

for server in $servers
do
    LOCAL_VAR=<some_value>
    ssh $server <<-EOF
    command1 $LOCAL_VAR
    command2..
    ..
    exit
    EOF
done

Take care when you copy paste this, sometimes you can have surprises with tabs or spaces.
