Input redirection and for loop
Hello,

I need help with a bash script that I try to improve. I could not find answer so far, maybe because I'm not to familiar with the terminology so feel free to correct my language.

I have a script that looks like:
Code:
NODES="node_a node_b node_c"
for NODE in $NODES
do
    FILE=${NODE}.log
    
    connect << EOF > $FILE
        findVersion $NODE
EOF

    echo "$NODE completed."
 done


This works fine. My problem is that `connect' command takes long time to start and I wanted to do for loop inside the connect << EOF > ..... EOF construction so my connect command will be executed only once. The issue is that for will not work inside there and will be written to the input of connect command where it miserably fails.

Could someone suggest how can I overcome this?

THanks, PN.
