Attempting to use a while loop on a file.... 3

[jdespres]

I'm attempting to loop tru a two column file with 38 lines of data.....

1st column = CLIENT
2nd column = GRID

cat file | while CLIENT GRID
do
echo "**************** $GRID $CLIENT ****************"
ssh admin@$GRID /usr/local/avamar/bin/mccli activity show --name=$CLIENT
done

It processes the 1st line then dies.....

Any idea's?

Thanks.....

Change your file descriptor like so:

while read -u 3 CLIENT GRID
do
echo "**************** $GRID $CLIENT ****************"
ssh admin@$GRID /usr/local/avamar/bin/mccli activity show --name=$CLIENT
done 3< file

That worked!

Not sure why..... But it worked!

Thanks!

Or, alternatively, ssh -n should also work.

The documentation of that option on the ssh man page will give you a clue why both solutions work; ssh grabs stdin from the controlling loop and gobbles up the rest of the input data.

Awesome!

ssh -n worked!

Thanks!
