Have you tried asking a coding AI assistant ? I've used github co-pilot to write all kinds of scripts for me, it is astonishingly easy, although be sure to check the code before deploying it. Sent from my Galaxy -------- Original message -------- From: Paul Sutton via list <list@xxxxxxxxxxxxx> Date: 24/10/2025 16:36 (GMT+00:00) To: DCGLUG <list@xxxxxxxxxxxxx> Cc: Paul Sutton <zleap@xxxxxxxxxxx> Subject: [LUG]writing shell scripts I am trying to write a shell script that when run will read a text file, which contains a list e.g item1 item2 item3 and for now echo the first line to stdout and in the case of what I have send to another text file #display first line of a file head -n 1 lines.txt > topline.txt #delete first line of a file sed -i -e "1d" lines.txt cat topline.txt But I don't think this is at all the correct way to do this. I am trying to find out how, but The ultimate aim of will be to Take a text file or list of urls (lets say Code Club Activities) Run the script say, every monday at 02:00 am each time the script is run, it will use the toot (mastodon cli tool) to send that url to a Mastodon account. then the next time it is run, send the next url in the list. I think I need to start by identifying the correct way to do this, then write or get help writing the a script to do this. I should not have a program getting a shell script to run at an allotted time each week using cron. So for example https://projects.raspberrypi.org/en/projects/space-talk https://projects.raspberrypi.org/en/projects/catch-the-bus https://projects.raspberrypi.org/en/projects/find-the-bug https://projects.raspberrypi.org/en/projects/silly-eyes https://projects.raspberrypi.org/en/projects/surprise-animation I had some help before with regard to reading an array containing a list of files, which then runs on all entries in the array. However, in this case the script will run and act on the first item, then run again a week later and act on the 2nd item. So it needs a way to track which item to send. So over a period of 5/6 weeks I send out a different activity each week. However, I also appreciate that sending out just a url is not very friendly or helpful, so there should be some text wrapped around it. I could perhaps create a series of text files with url and wrapper text. Hopefully, this can be run on a Raspberry pi, and it can just be left on and do tasks at allotted times. Could someone help / advise please.
