frr fails to input from /dev/stdin using -f in 9.0

[jfgibbins]

Using version 8.5 and prior the following command will add config to running instance of frr

$SUDO vtysh -f /dev/stdin <<EOF
ip router-id 10.8.88.1
EOF

config is sample...doesn't matter what commands you're trying to add

starting with 9.0 this no longer works

• Did you check if this is a duplicate issue?
• Did you test it on the latest FRRouting/frr master branch?

To Reproduce
see above

Versions
Ubuntu 22.04 - latest build of cloud image

qq: does normal redirecting work, or fail the same way? i.e.,

cat <<EOF | sudo vtysh
ip router-id 10.8.88.1
EOF

if I adjust yours to include a line for "conf t" it will take the command. I'm guessing cli without a parameter is defaulting to using -c for arguments, as if you were at a command prompt in vtysh.
I did notice though, when using -f as in the original post, it does oddly accept a statement for "ip route x.x.x.x/xx dest", but no other commands.

This worked quite well prior to 9.x. Has the method of usage been deprecated, or was it an "unrealized enhancement"?
