Expect script fails to check file exists or not in remote node

Dear members, The following expect script connects to remote node and check for the file "authorized_keys" in directory /root/.ssh in remote node. However the result is always found even if the file exist or doesn't exist.

Code:
expect {
"$fname" {
send_user "found\n"
}

Any idea what is causing this issue and how to fix it please ?

Thanks.

Code:
spawn ssh -q -o GlobalKnownHostsFile=/dev/null -o  \
UserKnownHostsFile=/dev/null -o CheckHostIP=no -o StrictHostKeyChecking=no $USER@$SYSTEM
expect "password:"
send "$PASSWORD\n"
expect "$ "
send "mkdir -p .ssh\r"
expect "$ "
set fname /root/.ssh/authorized_keys
set timeout 2
expect {
"$fname" {
send_user "found\n"
}
timeout {
send_user "not found\n"
}
}
