### Format the output (--format) {#format}
The formatting option (`--format`) will pretty-prints history output
using a Go template.
Valid placeholders for the Go template are listed below:
| Placeholder | Description |
|-----------------|-----------------------------------------------------------------------------------------------------------|
| `.ID` | Image ID |
| `.CreatedSince` | Elapsed time since the image was created if `--human=true`, otherwise timestamp of when image was created |
| `.CreatedAt` | Timestamp of when image was created |
| `.CreatedBy` | Command that was used to create the image |
| `.Size` | Image disk size |
| `.Comment` | Comment for image |
When using the `--format` option, the `history` command either
outputs the data exactly as the template declares or, when using the
`table` directive, includes column headers as well.
The following example uses a template without headers and outputs the
`ID` and `CreatedSince` entries separated by a colon (`:`) for the `busybox`
image:
```console
$ docker history --format "{{.ID}}: {{.CreatedSince}}" busybox
