An administrator needs to send a maintenance notice to all logged-in users except the user 'backup' who is running a critical script. The notice text is in /root/notice.txt. Which approach works?

Use wall with the --nobackup option

wall < /root/notice.txt, then use write to send the notice to backup separately

Use write to each user individually, skipping backup

Use write backup < /root/notice.txt, then wall < /root/notice.txt

A server is accessed via SSH and local console. The administrator wants to display a maintenance notice only to users who log in via SSH, not to local console users. Which approach should be used?

Configure the Banner directive in /etc/ssh/sshd_config

A system administrator needs to send a message to the user 'alice' who is logged in on two terminals (tty1 and pts/0). The message should only appear on tty1. Which command should be used?

wall alice tty1 'Meeting at 15:00'

write alice tty1 'Meeting at 15:00'

echo 'Meeting at 15:00' > /dev/tty1

A server is being patched and will be unavailable for 30 minutes. The administrator wants to prevent any new logins during this window, but does not want to shut down the system. Which action should be taken?

Create /etc/nologin with a message explaining the maintenance

Run wall 'System unavailable for 30 minutes'

Edit /etc/issue to include the maintenance message
