Usage

nft-edit-ruleset [ --timeout SECONDS | --config [CONFIG_FILE] ] [--fail] [--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.
