How do you get the thing to stfu?

(In my firewall sh script I want to test whether or not a chain already exists -- to either create it or flush it.)

# iptables -L THISISNOTACHAIN 2>&1 >/dev/null; echo $?
iptables: No chain/target/match by that name.

Try `>/dev/null 2>&1` - see [Order of redirections](https://unix.stackexchange.com/questions/37660/order-of-redirections) – steeldriver Jul 01 '21 at 16:17
That is the solution! – Richard Barraclough Jul 01 '21 at 16:37
