./swizguard add isn't adding new clients

[G-only1]

The install script seems to have worked fine. However when i try adding a new client with sudo ./swizguard add it appears to complete successfully, but when i run sudo ./swizguard list it shows that I don't have any clients yet.

I am running on a brand new Ubuntu 24.04.4 LTS VM.

Steps to reproduce

1. Download with git clone https://github.com/0xXyc/SwizGuard.git
2. Open the directory and run `sudo ./swizguard setup'
3. Try adding a device with sudo ./swizguard add test
4. Check if the device was added with sudo ./swizguard list
5. no device added :(

I ran the add-client.sh script with xtrace sudo bash -x add-client.sh test and it looks like the script is stopping at line 42.

Exact same issue for me.

Just installed it on Debian 13;
Download with git clone https://github.com/0xXyc/SwizGuard.git
Open the directory and run `sudo ./swizguard setup'
Try adding a device with sudo ./swizguard add test
Check if the device was added with sudo ./swizguard list
no device added :(

After manually creating the missing directory;

I fixed that by changing the following lines 41-42 in /swizguard/scripts/add-client.sh

HIGHEST=$(grep -oE "${WG_SUBNET//./\\.}\.[0-9]+/32" /etc/wireguard/wg1.conf 2>/dev/null \ | awk -F'[./]' '{print $4}' | sort -n | tail -1) HIGHEST=${HIGHEST:-1}

with;

HIGHEST="$( grep -oE "${WG_SUBNET//./\\.}\.[0-9]+/32" /etc/wireguard/wg1.conf 2>/dev/null \ | awk -F'[./]' '{print $4}' | sort -n | tail -1 || true )" HIGHEST=${HIGHEST:-1}

add-client.sh runs with set -euo pipefail. Then it tries to detect the highest already-used client IP by grepping /etc/wireguard/wg1.conf. On a fresh install there are no [Peer] entries yet, so that grep returns exit code 1 and the script fails.
