如何在 Linux 命令行中以纯文本形式查看 Wi-Fi 密码？

Question

我已通过以太网连接到互联网，但已保存 wifi 密码。

该文件夹/etc/NetworkManager/system-connections是空的。

此命令不显示任何内容（将变量替换为所需的 uuid）：

# nmcli -s -g 802-11-wireless-security.psk connection show $UUID

这也没有帮助：

# for uuid in $(nmcli -g UUID connection show); do
    nmcli -g 802-11-wireless.ssid,802-11-wireless-security.psk connection show $uuid | awk -F: '{
        if (NR == 1) printf "SSID: %s\n", $0;
        if (NR == 2) printf "Password: %s\n\n", $0;
    }'
done

该代码的输出：

SSID: Home_WiFi
Password: <hidden>

SSID: Starbucks_clients
Password: <hidden>

SSID: Sony_phone_hotspot
Password: <hidden>

有什么帮助以纯文本形式获取密码吗？它们被存储在某个地方，因为 wifi 会自动重新连接和验证，无需重新输入密码。

这些是 @Raffa 建议的命令，经过一些小修改：

# nmcli dev wifi show-password
Error: No Wi-Fi device found.

# for conn in $(nmcli -t -f NAME con show); do
    echo "Details for $conn:"
    nmcli connection show "$conn" --show-secrets | grep 802-11-wireless-security.psk
done

Details for Wired:
Error: Wired - no such connection profile.
Details for connection:
Error: connection - no such connection profile.
Details for 1:
Error: 1 - no such connection profile.
Details for lo:
Details for virbr0:
Details for Home_WiFi:
802-11-wireless-security.psk:           --
802-11-wireless-security.psk-flags:     1 (agent-owned)
Details for Starbucks_clients:
802-11-wireless-security.psk:           --
802-11-wireless-security.psk-flags:     1 (agent-owned)
Details for Sony_phone_hotspot:
802-11-wireless-security.psk:           password1
802-11-wireless-security.psk-flags:     0 (none)

现在，有些网络显示密码，而另一些则不显示。

密码由 存储/usr/bin/kwalletmanager5。知道如何从命令行提取它们吗？
