Put a command into router through sshpass bash script

hello, i am facing some issue. I am using a simple bash script that via sshpass put a command into router. Now, problem is that i have a file and commands into it.

sshpass -p $pass ssh -o $log -n $user@$h /ip address set [/ip address find address="10.0.0.2/24"] address=10.0.0.1/24

so if I have that command

ip address set [/ip address find address="10.0.0.2/24"] address=10.0.0.1/24

into a file name test.txt how can I put from file to my sshpass command?
