This is starting to become a thing. When I need to relax, I end up playing with bash.
This time I set up a dynamic Message of the Day (motd). For the uninitiated, typically bash will print out the contents of a text file upon the creation of a new login session. In this case, I cleared out that file and added a couple lines to my bash_profile to run this script in its place.
top seemed pretty hamfisted, so I call it (and other commands) just once and save the output to a variable that I can read later on.
I rather liked the idea of shortening my bash prompt, so the warm welcome includes the current username.
Uptime and Load data took a bit of finagling. I am no
awk expert and so things here could probably be cleaned up by someone who actually knows what they’re doing, but I just threw
sed at the problem and got it working.
In keeping with the idea of shortening my bash prompt, I also included the system hostname in the motd. I already try not to leave sessions open, so now I should always know where and who I am without sacrificing those precious columns.
