# How to use cronjobs

This guide provides examples on how to use cronjob to automate tasks. _This was tested on Ubuntu 22.04._

## Get Started

- Begin by opening a terminal and running the following command:

```bash
crontab -e
```

This command will open the crontab file in the nano text editor.

- Next, you need to define the cronjob. Add the following lines to the file:

```bash
* * * * * <command>
```

- Finally, you can save the file by pressing `Ctrl + X` and then `Y`.

## Syntax

```bash
* <- minute (0-59)
  * <- hour (0-23)
    * <- day of month (1-31)
      * <- month (1-12)
        * <- day of week (0-6) (Sunday=0)
          <command>
```

## Examples

### Run a command every minute

```bash
* * * * * <command>
```

### Run a command every 5 minutes

```bash
*/5 * * * * <command>
```

### Run a command every hour

```bash
0 * * * * <command>
```

### Run a command every day at midnight

```bash
0 0 * * * <command>
```
