This MOTD has so many colors! This thing is from hell.
It's colourful. It shows a lot. It's fun.
But I guess we have reached the limit.
The execution is sometimes too slow.
It makes it annoying when you log in.
So be careful.
I warned you.
## Preview
The most of the icons in this preview are from Font Awesome 5 Pro.
I also used [fontello](http://fontello.com/) to create some own icons.
## Setup
1. Check the dependencies.
Some modules require `jq`, the banner needs `figlet`.
Install them.
2. Copy `motd-on-acid.sh` to `~/.bashrc_motd` on your system.
3. Run `motd-on-acid` at the end of your `.bashrc`.
Add the modules as arguments.
The output is ordered in the same way.
4. Replace the predefined values with your own.
The complete list of vars is [at the top](motd-on-acid.sh#L4) of the script.
```sh
# example snippet for your .bashrc:
source ~/.bashrc_motd
BANNER_KERNEL_ICON="X"
BANNER_UPTIME_ICON="Y"
BANNER_DEBIAN_ICON="Z"
bash_motd --banner --processor --memory
```
### Make it better
If you use the example above you will get some problems.
1. You only want to see `motd-on-acid` if you login with `ssh` on an interactive shell.
2. You need a way to disable it sometimes.
The result would look like this:
```sh
# example snippet for your .bashrc:
if [ -n "$SSH_CONNECTION" ] && [ $SHLVL -eq 1 ] && [[ $- == *i* ]]; then
if [ -z "$MOTD" ] || [ "$MOTD" -ne 0 ]; then
source ~/.bashrc_motd
BANNER_KERNEL_ICON="X"
BANNER_UPTIME_ICON="Y"
BANNER_DEBIAN_ICON="Z"
bash_motd --banner --processor --memory
fi
fi
```
Also add `AcceptEnv MOTD` to your `/etc/ssh/sshd_config`.
Now you can run `export MOTD=0; ssh -o SendEnv=MOTD -t host.name.net` to disable MOTD.
That is useful if you run `ssh` commands in scripts.
### Remove other output
You still have disturbing output which is not required.
Change some values in your `/etc/ssh/sshd_config`:
```
PrintMotd no
PrintLastLog no
Banner none
```
Disable or remove all `pam_motd.so` PAM includes in `/etc/pam.d/sshd`
```
# session optional pam_motd.so
```
