# Running a script automatically every morning on Linux

The usual tool for this is `cron`, a scheduler that ships with almost every
Linux system. You hand it a time and a command, and it runs the command on that
schedule in the background.

## The five time fields

A cron schedule is five time fields followed by the command to run:

| Field | Meaning      | Range           |
| ----- | ------------ | --------------- |
| 1     | Minute       | 0-59            |
| 2     | Hour         | 0-23            |
| 3     | Day of month | 1-31            |
| 4     | Month        | 1-12            |
| 5     | Day of week  | 0-6 (Sun = 0)   |

An asterisk means "every value", so `30 7 * * *` reads as 7:30, every day.

## Add the job

Open your personal crontab:

```bash
crontab -e
```

Add one line that runs your script at 7:30 each morning:

```bash
30 7 * * * /home/you/backup.sh >> /home/you/backup.log 2>&1
```

The `>> ... 2>&1` part appends both normal output and errors to a log file,
which you will be glad of the first time something breaks.

## A few things worth knowing

- Cron runs with a bare environment, so use absolute paths and do not lean on
  your shell's `PATH`.
- Make the script executable first: `chmod +x backup.sh`.
- Test the command on its own before trusting the schedule. Cron only tells you
  it ran, not that it worked.

If the machine is asleep at 7:30 the job is skipped, not caught up later. For a
laptop that sleeps, `anacron` is the better fit.

How it works

Turn a ChatGPT answer into a PDF

Copy the answer

In ChatGPT, use the copy button under the reply, or select the text and copy it. Either way you get the raw Markdown: headings, tables, code and all.

Paste it here

Drop it into the source pane on the left. The proof on the right typesets as you paste, and leftover "Copy code" or "ChatGPT said:" litter is trimmed for you.

Save as PDF

Press Download PDF and choose "Save as PDF" in the print dialog. That is the finished document, no signup and no watermark.

Other ways to do it

When another route makes more sense

topdf.md is the quick path for a single answer. It is not the only way to get a PDF out of ChatGPT, and for some jobs another route is genuinely better. Here is the honest version.

A whole conversation

To capture an entire chat rather than one answer, open it in ChatGPT and use your browser's print (Cmd or Ctrl+P), then "Save as PDF". You keep every turn, though the look is the chat interface's, not typeset.

ChatGPT's data export

For an archive of everything you have ever asked, Settings then Data controls then Export gives you a downloadable file. It is a backup, not a shareable document, so expect raw HTML rather than a clean PDF.

A browser extension

An extension that adds a save-as-PDF button inside ChatGPT is handy if you export constantly and want it one click away. The catch with the popular free ones is a watermark and a cap of around three PDFs a day. If that suits you, fair enough.

Questions

Is converting ChatGPT to PDF free?

Yes. No signup, no watermark, and no daily limit on how many you save. The converter is free, and the paid extras planned later (custom themes, a document API) do not touch it.

Do I need a browser extension?

No. topdf.md is a web page, so you paste the answer and save the PDF right here. Nothing to install, and nothing bolted onto ChatGPT itself.

Is my ChatGPT conversation uploaded anywhere?

No. The answer you paste is rendered and turned into a PDF entirely in your browser. It is never sent to a server, stored, or logged. Close the tab and it is gone.

Does the code and formatting survive?

Yes. Headings, tables, task lists, and fenced code blocks with syntax highlighting all come through, because ChatGPT writes GitHub-flavored Markdown and that is exactly what this renders.
