Run shell script at startup (Kali Linux)

0

This seems like a very basic thing to do, and I have even followed a few tutorials to get a simple script to be run at startup, but to no avail.

Here is what my script, which is in the root directory, looks like:

#! /bin/bash
xmodmap ~/.xmodmaprc
echo 0 | sudo tee /sys/module/hid_apple/parameters/iso_layout

The script basically changes my keymap, by switching control and command keys (as I'm on a macbook). It has been chmod'ed to be executable, so that it executes successfully when I do ./keymap_fix.sh or I do /root/keymap_fix.sh

I have followed these simple tutorials https://www.cyberciti.biz/tips/linux-how-to-run-a-command-when-boots-up.html and https://www.cyberciti.biz/faq/linux-execute-cron-job-after-system-reboot/

So, I have copied the shell script to /etc/init.d and did this also update-rc.d keymap_fix.sh defaults 100

I even tried setting up crontab in a similar way, by adding @reboot /root/keymap_fix.sh , but nothing works! Whenever I reboot, my keymap remains the same. :/

Would be grateful if someone could help me out here, thanks!

Tried that already, @davidgo – SinByCos – 2017-08-28T08:47:55.040

I think you are misunderstanding the difference between "boot time" (system wide) and "login" (user specific) when using the term "startup". There is no point in running xmodmap at boot time (with SystemD or /etc/init.d), as it acts on the an X client (which is not running at that point in time). I think you want to add your commands in the shell init file (like .bashrc). – Dirk – 2019-09-25T17:19:54.207

Actually you describe two problems: You want to have the correct keymap on your PC. (This should be obtained by correctly configuring your system config files for the X client.) But you ask for help with a solution (start script automatically at "startup"), which in my opinion is sub-optimal for your initial problem. – Dirk – 2019-09-25T17:22:49.453

I'm not really familiar with Kali, but as I remember it does have systemd installed.

So, systemd is a good thing and I think it fits to your problem. Using it is easy and is a common thing used widely in practice.

Here you can read more about it. Basically you need to add a service config to your service scripts, which runs your script, and you're done. If you need an example, feel free to ask.
