When running scripts which take a long time, i don’t want to wait for things to finish before i can start the next one.
For example, using my dedup script or compiling stuff. I wanna know when it is finished.
So i made some scripts
Maybe you can hear the spoken text in the background playing downstairs
I’ve put a function in .bashrc, so i can use a command like notify “Compiling is ready” A command like this i can put at the end of a command or in a script file at the end. make && make install && notify “compile ready”
What does it do when executed?
Send a mqtt message to the broker
Node-red will read this message and:
Send a message to my display on my desk – Sound and message notification. (See another post how i made this )
Send a message to a script on my Domoticz instance downstairs.
This will use a script to get a speech file from google, and play this on some small speakers in my livingroom
Send a pushover message to my phone
Display a message on my TV ( not in code below )
How?
At the end of your .bashrc
function notify() {
if [ -z "$1" ]; then
echo "Usage: $0 \"message\"";
exit 1;
fi
mosquitto_pub -h 10.1.0.17 -t notify/bashscript -m "$1"
}
This script will look for a cached audiofile with requested text, and uses that. Else it wil request a audio file from google, caches it and plays it though the speakers.
#!/bin/bash

Added custom fields to Phpipam, so i can remove my port sheet and administer everything in Phpipam. And to prepare for a Augmented reality project i want to create.
Howto add fields: Go to the administrator menu on the right. Select IP related management > Custom fields Custom IP addresses fields press the plus sign Give it a name and description. I’m using varchar(10) at the moment so i can enter switchname:port (media:4)
See below for a example: Using a QR code and the information, i want to display port information using a app.
Sorting out my fileserver, i had the need for a deduplication script. Many files i’ve been copying from backup, clouds mobile devices and workstation. Inevitable to get many copies.
Below script walks a directory, using locate it tries to find files with same name. Using a md5sum it wil check if it is the same file, when found a simular file it stops searching, removes the one from the check-directory and checks the next one.
#!/bin/bash
# Copy this script to your to clean directory,
# when you got a copy on your fileserver from this script
# then the copy in your clean dir will be removed also.
# Dont want that? change
# find -type f |
# into
# find -type f | grep -v <nameofthisscript> |
# dont is current directory, skip these from locations
dont=$(pwd)
# Never start in /mnt ? uncomment below
# echo "$dont" | grep "^/mnt" && ( echo "start in tank" ; exit )
find -type f | while read file ; do
filemd5=$(md5sum "$file" | cut -f1 -d" ")
basenamefile=$(basename "$file")
echo "searching $basenamefile"
locate -i "/$basenamefile" | grep -v "$dont" | while read location ; do
if [ -f "$location" ] ; then
locatedfilemd5sum=$(md5sum "$location" | cut -f1 -d" ")
if [ "$filemd5" == "$locatedfilemd5sum" ] ; then
echo "found same md5sum at $location"
rm "$file"
break
fi
fi
done
done
# Remove empty dirs?
# find . -type d -empty -delete
Locate can be slow, sometimes it is better to put the locate DB in memory of on another fast storage system.
I’ve been using this for a while now, and i’m really impressed by it. It just connects to the Serial Din of your C64, draws power from the Cassette port. … And even looks like a mini drive!
I’ve been converting Disks to images as well as runnig previously converted D64 images on a real C64 again.
Also the internet provides loads of images to run again.
Converting and running:
For real floppy to image i used a empty image file. Made my real original drive device number 9, and used Dracopy (also below)
Image running on your real C64, just put a D64 disk image on your SDcard.
There is a disk selector and run program you can use. (See below) Also you can use the buttons for disk swap/change.
Running a little program to read dipswitches and displaying them using leds.

For my amiga i started to build a floppy disk reader/writer using a arduino. I found a superb project by rob smith. It uses only a arduino pro and a FTDI USB to serial breakout board, to raw read and write disks. I wanted to convert my own created amiga disks to PC image to use in a emulator like vice.
