在 ubuntu 中使用 shell 脚本获取不提示输入密码的无线接入点名称或 ssid

我只是想在 ubuntu 中使用 shell 脚本获取不提示输入密码的无线接入点名称或 ssid 列表。

或者我可以说我想获取机器保存或记住其密码的 ssid 或无线接入点名称列表。因此，当用户尝试连接它们时，它将自动连接（不会在弹出窗口中提示手动输入密码）。

我正在使用以下命令来获取 ssid。

  1. nmcli -t -f ssid dev wifi| cut -d \' -f2
  2. iwlist wlan0 扫描

这些命令显示所有 ssid，但我只需要机器保存或记住的密码的 ssid。

如果有人对我的问题有任何想法，请告诉我。

以下是命令“sudo iwlist wlan0 scan”的输出。

谢谢。

我想说你需要三样东西

  1. sudo iwlist wlan0 scan | grep "Encryption key:off" -A 1检查当前可用的任何不需要密码的网络的结果，以及可能的new系统的结果

  2. 检查内容以/etc/NetworkManager/system-connections获取系统已保存网络的列表。如果网络以系统范围访问权限保存，那么您还会在那里找到密码（psk字段），如果它不需要任何密码，则它将没有安全字段。

  3. 对于网络管理员没有设置系统密码的网络，密码将保存在gnome 钥匙圈钱包。你可以从这里开始学习如何与它交互：https://blog.schmichael.com/2008/10/30/listing-all-passwords-stored-in-gnome-keyring/

当然，这是假设您使用的是常规的 Ubuntu 发行版。
