I have a script in a folder:
I need this script to run every time the system starts (even if no one logs in to the system). What do I need to do in order to make this happen?
You will need root privileges for any the following. To get root, open a terminal and run the command
and the command prompt will change to '#' indicating that the terminal session has root privileges.
with content like the following:
# This script is executed at the end of each multiuser runlevel /path/to/my/script.sh || exit 1 # Added by me exit 0
with content like the following
description "my job" start on startup task exec /path/to/my/script.sh
Create a new script in
(Obviously it doesn't have to be called "myscript".) In this script, do whatever you want to do. Perhaps just run the script you mentioned.
Make it executable.
chmod ugo+x /etc/init.d/myscript
Configure the init system to run this script at startup.
update-rc.d myscript defaults
You don't need root, or to even login.
You can edit your crontab (
crontab -e) and create an entry like this:
This way, you can run it as a regular user.
@reboot just means it's run when the computer starts up (not necessarily just when it's rebooted).
P.S.: Regarding comments that this does not work properly
Some have said that this doesn't work on Debian-based distros, such as Ubuntu. I have personally successfully used this method on both Ubuntu and Mint. There are a few things to consider, however.
@reboot jobs will run when the cron daemon starts. I've found that on Debian-based distros, this may occur before the
/home partition has been mounted. If the script you're running is in your home folder, it will fail.
Additionally, this isn't limited to Debian-based distros, but if your home folder is encrypted, it may not be decrypted until after you login. There is probably no way around this.
Also, your network interface may not be up yet, and if the command requires Internet access, it may fail.
Finally, again, this is not limited to Debian-based distros, but cron runs under a much more limited environment than your shell runs under. In particular, the
PATH variable has much fewer paths. It is possible that the command being run isn't found, if it's in, for example, something like
$HOME/.local/bin, which may be in your
PATH in your shell session, but not under
cron. It's even possible that the command being run depends on some environment variable that's not set in
So, there are a number of reasons why your command will to run under cron, but it's not because
@reboot doesn't work on your distro.
Comment value and add to file:
[Desktop Entry] Type=Application Exec=/full/link/to/your/newshell.sh Name=newshell Comment=whatever you want
you can do it from GUI:
In your home, you have a file named .bashrc. This file is executed at the opening of your session.
Just put something like this at the end of the file:
EDIT: sorry, i didn't answer your question because my solution is executed when a user is logged in...
To execute something before the login, you can try rcconf or rc-file: http://www.debianadmin.com/manage-linux-init-or-startup-scripts.html
