# Usage

```
nft-edit-ruleset [--config [CONFIG_FILE]] [--fail] [--timeout SECONDS] [--yes] 
```

# Description

Interactively edit the current nftables ruleset using the editor specified by
environment variable EDITOR (defaulting to vim). Optionally, revert changes
after a timeout given in seconds.

# Options

- `-c`, `--config [CONFIG_FILE]`:  
  If set, on successfully applying changes, save the resulting ruleset to
  `CONFIG_FILE` (if `CONFIG_FILE` is not specified, it defaults to
  /etc/nftables.conf).  
  This option is mutually exclusive with option `--timeout`.
- `-f`, `--fail`:  
  Exit on changes failing to apply instead of prompting the user for re-edit.
- `-h`, `--help`:  
  Display this message and exit.
- `-t NUM`, `--timeout NUM`:  
  Revert any changes NUM seconds after they have been applied. This is
  implemented with a systemd timer that remains active after the program
  has ended.  
  This option is mutually exclusive with option `--config`.
- `-y`, `--yes`:  
  Do not prompt for confirmation before applying changes.

# Exit Codes

- 0: Success: No changes to apply or changes applied successfully.
- 1: Error: Usage error or failed or aborted changes.
