# fmt
|
|
|
|
This is a stand-alone utility to pretty-format your `dnsconfig.js` configuration file.
|
|
|
|
```shell
|
|
NAME:
|
|
dnscontrol fmt - [BETA] Format and prettify a given file
|
|
|
|
USAGE:
|
|
dnscontrol fmt [command options] [arguments...]
|
|
|
|
CATEGORY:
|
|
utility
|
|
|
|
OPTIONS:
|
|
--input value, -i value Input file (default: "dnsconfig.js")
|
|
--output value, -o value Output file
|
|
--help, -h show help
|
|
```
|
|
|
|
## Examples
|
|
|
|
By default the output goes to stdout:
|
|
|
|
```shell
|
|
dnscontrol fmt >new-dnsconfig.js
|
|
```
|
|
|
|
You can also redirect the output via the `-o` option:
|
|
|
|
```shell
|
|
dnscontrol fmt -o new-dnsconfig.js
|
|
```
|
|
|
|
The **safest** method involves making a backup first:
|
|
|
|
```shell
|
|
cp dnsconfig.js dnsconfig.js.BACKUP
|
|
dnscontrol fmt -i dnsconfig.js.BACKUP -o dnsconfig.js
|
|
```
|
|
|
|
The **riskiest** method depends on the fact that DNSControl currently processes
|
|
the `-o` file after the input file is completely read. It makes no backups.
|
|
This is useful if Git is your backup mechanism.
|
|
|
|
```shell
|
|
git commit -m'backup dnsconfig.js' dnsconfig.js
|
|
dnscontrol fmt -o dnsconfig.js
|
|
git diff -- dnsconfig.js
|
|
```
