script Send command with SH - bash

Question

I would need a .sh script that allows me to read only the second line of a file and then send it to machine B.
Example file:
timestamp_pippo.csv
"Row1_skipped"
"Row2_send_to_machine"
the file is in the path:
C:\Program Files\Splunk\var\run\splunk\csv
only the second row "row2_send_to_machine" (contains a unix command) must be sent to machine B
once the command has been sent, the file timestamp_pippo.csv must be deleted.
can you help me? I'm not familiar with .sh
what I've managed to create so far is only this:
for a in $(C:\Program Files\Splunk\var\run\splunk\csv cat timestamp_pippo.csv|grep -v Row1_skipped);do
ssh unix_machine#11.111.111.11 $a
done

Answer 1

Since you want to retain the for loop:
for cmd in $(head -2 timestamp_pippo.csv | tail -1); do ssh <machine> $cmd; done
Though tbh, this is bad - if you actually extend this and use the loop, you will be doing multiple connects to the ssh machine. Better to create the batch file you want, then do one ssh and run the batch. Here's a decent explanation of running a local script on a remote host: https://unix.stackexchange.com/questions/313000/run-local-script-with-local-input-file-on-remote-host

Answer 2

Thanks for the reply. I've solved with this script:
path="/home/weblogic/testCSV/*.csv"
for a in $(ls -lrt $path|awk '{print $9}');do
#echo $(head -2 $a | tail -1)
ssh unix_machine#11.111.111.11 $(head -2 $a | tail -1)
rm $a
#echo "file $a removed"
break
#echo "send command"
done
Steps:
-check the file
-execute the old file
-remove the file
The command we have to send to machine B is in the second line of the file timestamp_pippo.csv.
Another question:
How I can authenticate me in the machine B?
