MOTD login display

[Kasyx]

I have recently set up my home router/firewall box, and at the moment I am just messing about with it. I have just been setting up /etc/motd so I can have a pretty message greet me when I log in. What I would like to know is if there is any way to display useful information in the MOTD (i.e. system uptime, disk usage, etc.)?

SHH!

I was trying to appear legitimate

Why update information in MOTD? IMHO, the best place to call information would be in ~/.login

Excuse me a moment...

*facepalm*

Let's pretend this topic doesn't exist.

Yeah, I'm just writing a script to show all the info I need which will be executed by my .bashrc file

Thanks for the help.

Here's my desktop version of /etc/profile.d/motd.sh:

There's some bash specific stuff in there so you might want to change /bin/sh to /bin/bash on Ubuntu etc. Could do a csh version too if needed. It's just that bash is my default sh on FreeBSD and Slack.

#!/bin/sh
nCPU=`cat /proc/cpuinfo | grep -c 'processor'`
declare -a CPU[${nCPU}]
MEM=`free -t | grep -w 'Mem' | awk '{print $2}'`
SWAP=`free -t | grep -w 'Swap' | awk '{print $2}'`
let MEM="$MEM/1024"
let SWAP="$SWAP/1024"
echo
for i in `seq 1 ${nCPU}`
do
    CPUMOD=`cat /proc/cpuinfo | grep -m 1 -w 'model name' | awk -F: '{print $2}'`
    CPUSPEC=`cat /proc/cpuinfo | grep -m 1 -w 'cpu MHz' | awk -F: '{print $2}'`
    echo "CPU[${i}]:${CPUMOD} @${CPUSPEC} MHz"
done
if [ ! -z ${JAVA_HOME} ]; then
    echo "JRE   : ${JAVA_HOME}"
fi
echo "MEM   : ${MEM}MB"
echo "SWAP  : ${SWAP}MB"
echo

That's quite impressive.

Thanks
