How to substitute each line into the execution of a command from a BASH file?

Question

bash

I want to connect to each computer on the network and execute the same command (pdsh is not suitable), so I decided to write a script

#!/bin/bash
FILE=$1
while read LINE; do
sshpass -p 123456 ssh -o UserKnownHostsFile-/dev/null -o StrictHostKeyChecking=no [email protected]$LINE 'date'
done < $FILE

I execute ./inst ip
It substitutes the ip value only from the first line, but how can I make it substitute all subsequent ones in turn?

Answer 1

for fl in `cat $1`; do
    sshpass -p 123456 ssh -o UserKnownHostsFile-/dev/null -o StrictHostKeyChecking=no [email protected]$fl 'date'
done
