Question

I want to send a few commands (functions) that are inside a simple .sh file AND stay logged in when ssh-ing to a remote computer.

I’ve tried many ways, but none have worked so far.
Here’s just one:

msh(){
    SERVER=$1
    LOCAL=10.20.1.1
    SSHF=`cat /tmp/sshf.sh`
    ssh $SERVER -R 47471:$LOCAL:22 "$SSHF; bash --login"
}

I’ve also tried copying over the file with pipes and streams and whatnot, none have worked.

You need to reserve a terminal at $SERVER, you do this with the -t switch. If I change your function to:

msh(){
    SERVER=$1
    LOCAL=10.20.1.1
    SSHF=`cat /tmp/sshf.sh`
    ssh -t $SERVER -R 47471:$LOCAL:22 "$SSHF; bash --login"
}

It seems to do what you want.
