To use systemd to run a bash script at 11am each day, you can create a new systemd service file. Here is an example of what the service file might look like:
```
[Unit]
Description=Run My Script
[Service]
Type=simple
ExecStart=/bin/bash /path/to/my_script.sh
[Install]
WantedBy=default.target
```
Save this file to `/etc/systemd/system/my_script.service`.
Then you can use systemd to schedule the script to run at 11am each day by creating a new systemd timer file. Here is an example of what the timer file might look like:
```
[Unit]
Description=Run My Script Daily at 11am
[Timer]
OnCalendar=*-*-* 11:00:00
[Install]
WantedBy=timers.target
```
Save this file to `/etc/systemd/system/my_script.timer`
Then you can enable and start the timer with the following commands:
```
sudo systemctl enable my_script.timer
sudo systemctl start my_script.timer
```
This will run the script at 11am everyday
You can check the status of the timer with the following command:
