I am developing a simple script, which connects to certain computers and executes, through an
ssh session, certain commands:
sshpass -p 'password' ssh $target_ip << EOF echo \$PATH # example echo \$HOSTNAME [...] EOF
The operation is correct, but it bothers me that on each connection it shows the
ssh server banner and interferes with the rest of the script's

Therefore, I do not want that banner to be displayed and only the outputs of the commands I execute inside the
Just in case it was relevant, the version of SSH I'm using is
OpenSSH_9.1p1, OpenSSL 3.0.7 1 Nov 2022. In the case of the server, it is
OpenSSH_8.2p1 Ubuntu-4ubuntu0.3, OpenSSL 1.1.1f 31 Mar 2020.

ssh -o LogLevel=error $ip
ssh -q $ip
How can I disable this at the client level? is there no ssh option or parameter that will allow me to do this? and in case of no, how can I redirect this
/dev/null without touching the outputs of the commands I execute inside the
