Inline comments:
In `@bash/nord/exit_node.sh`:
- Line 3: The script uses the wrong NordVPN CLI subcommand; in exit_node.sh
replace the command invocation that currently says "nordvpn set mesh on" with
the correct "nordvpn set meshnet on" so the Meshnet feature is enabled properly
(look for the exact string "nordvpn set mesh on" in the file and update it to
use "meshnet").
In `@bash/nord/nord_watchdog.sh`:
- Around line 27-32: The script currently uses the nonexistent subcommand
`nordvpn meshnet peer allow-exit-node set "$USER_EMAIL"` to grant exit-node
permission; replace it with the correct command `nordvpn meshnet peer routing
allow <device>` and pass the peer's Nord name, nickname, or Meshnet IP (as
obtained from `nordvpn meshnet peer list`) instead of an email; update the
conditional that checks for "Allowing to use as exit node: yes" to extract the
device identifier (e.g., nickname or IP) from `nordvpn meshnet peer list` and
use that identifier in the `nordvpn meshnet peer routing allow` command so the
permission is applied correctly.
In `@bash/nord/routing.sh`:
- Around line 1-3: The peer name is inconsistent across scripts (DellNord in
routing.sh, mesh-dell in routing.sh.save and mesh.sh, and DELL in exit_node.sh);
pick a single canonical peer identifier (e.g., mesh-dell) and update all
references to that exact string and casing so they match: change the nordvpn
command in routing.sh (nordvpn meshnet peer routing allow DellNord) to use the
chosen name, update mesh.sh and routing.sh.save to the same identifier, and
align any environment variable or constant like DELL in exit_node.sh to the same
canonical name to ensure consistency.
In `@bash/nord/routing.sh.save`:
- Around line 1-4: Remove the editor backup file routing.sh.save from the
repository and stop tracking it; delete the file from Git and add a .save or
editor backup pattern (e.g., *.save or common editor backups) to .gitignore so
similar files are ignored in future. Verify the intended script is preserved
under the correct name (e.g., routing.sh) if that command "nordvpn meshnet peer
routing allow mesh-dell" should exist in a committed script, and ensure only the
canonical script is tracked.
In `@README.md`:
- Around line 9-11: Replace the informal NordVPN section text ("Make me an
exit_node god damn it!") with a concise, professional description of the
scripts’ purpose; update the NordVPN section under the "### NordVPN" heading to
something like "Scripts for configuring NordVPN Meshnet and exit node
functionality" (or similar wording that clearly states what the scripts do).

Nitpick comments:
In `@bash/countLines.sh`:
- Around line 1-8: Add argument validation and robust file reading: check that
FILENAME (the "$1" argument) is provided and that the file exists and is
readable, otherwise print a brief usage message and exit with a non-zero status;
then modify the read loop that uses COUNTER and "while IFS= read -r line; do" so
it also processes a final line without a trailing newline by using the
read-or-last-line pattern (e.g., read ... || [ -n "$line" ]), preserving COUNTER
semantics and error handling.
In `@bash/nord/exit_node.sh`:
- Around line 11-14: The peer names are inconsistent across scripts

In `@bash/nord/nord_watchdog.sh`:
- Around line 34-39: The current block that reads IF_FORWARD and runs `sysctl -w
net.ipv4.ip_forward=1` only makes a transient change; update the watchdog to
persist the setting by writing the net.ipv4.ip_forward=1 into system sysctl

checks IF_FORWARD (variable IF_FORWARD and the `sysctl -w` call) to also ensure
the persistent configuration contains the setting and call the appropriate
reload/apply step.
- Around line 15-19: The current login check uses `nordvpn status | grep -q
"Status:"` which can be true even when disconnected; change the check in the
if-block that runs `nordvpn status` so it captures the command output into a
variable and tests for the specific "You are not logged in" (or similar

🌐 Web query:
NordVPN meshnet peer allow-exit-node command syntax and usage
💡 Result:
The NordVPN Meshnet CLI command to allow a peer device to use your device as an exit node (i.e., route traffic through it) is nordvpn meshnet peer routing allow <device>. Syntax: nordvpn meshnet peer routing allow <device> - Replace <device> with the peer's Nord name, nickname, or Meshnet IP address. Usage: 1. List peers: nordvpn meshnet peer list 2. Allow routing for a specific peer: nordvpn meshnet peer routing allow happy.matterhorn.nord (example) 3. To deny: nordvpn meshnet peer routing deny <device> This enables the "traffic routing through your device" permission on Linux, allowing the peer to connect via nordvpn meshnet peer connect <device> on their end. Note: there is no exact "allow-exit-node" command; "routing allow" is the equivalent for enabling a peer as an exit node host. Use tab completion for device names. For full help: nordvpn meshnet peer --help

Use correct command syntax for granting exit-node permission.
The command nordvpn meshnet peer allow-exit-node set "$USER_EMAIL" is incorrect. The correct command is:
nordvpn meshnet peer routing allow <device>
Replace <device> with the peer's Nord name, nickname, or Meshnet IP address (obtained from nordvpn meshnet peer list). The subcommand allow-exit-node does not exist; use routing allow instead, and pass a device identifier, not an email address.

Verify peer name consistency across nord scripts.
The script references peer DellNord, but the previous version (routing.sh.save) and mesh.sh both use mesh-dell. Additionally, exit_node.sh uses DELL for what appears to be a similar peer reference. Clarify whether the peer was renamed or if these scripts should use consistent naming—currently three different identifiers are used across the codebase (DellNord, mesh-dell, DELL).
