msg_all.sh:
#!/bin/bash
MSG="\"$*\""
if [ "$MSG" = "\"\"" ]; then
MSG="\"Rebooting in 5 minutes. Please save your data.\"";
fi
who | grep ":0/" | awk '{ print $1 " " $2 }' | sed 's/:0\///g' |
{
while read user screen;
do
su $user -c "xmessage -center -display $screen:0 $MSG &"
done
}
You can start it with ./msg_all.sh [message]
If you don't give an option it'll take the default message ...
Enjoy!
