Unable to connect morethan a server via remotely and get the result
 

Hello
Have a question.

Please refer my code

#!/bin/sh
i=1
while read line
do
echo "$i:$line";ssh $line 'nvidia-smi |grep -i MB | cut -c40-55'
let i++
done < ~/hostnames

There are ~100 server , i want remotely loginto all servers one by one and get the nvidia details, when i execute the above scrips it just fetch the details from one server post it quite, it does not heading to second server listed in hostnames file.

Please correct where i was wrong and wt should i do to fulfill my request

Please post a fragment of the output, and the hostnames file (in [CODE] [/CODE] tags please, to preserve formatting for those who will test the data).
--- rod.

Output should be as follows
1 144MB / 511MB
2 144MB / 511MB
3 144MB / 511MB

here is the hostname file
MM31.hyd
MM16.hyd
MM54.hyd
MM86.hyd

...and you didn't post the output you are getting, as was requested. Without knowing what it's doing, we can't help.

And again, please use CODE tags.

Does it quit after displaying output of first server, or stuck after that? Perhaps, it's not able to connet to second server...
Once add set -xv to debug the code, as:
