            proto=WPA
            key_mgmt=WPA-PSK
            psk=5f55a9b869e9ab6d03839cae23c7243accc0ac0a12079d358328bf73ad2e0ebe

    network={
           ssid="myssid2"
           scan_ssid=0
           proto=WPA
           key_mgmt=WPA-PSK
           psk=d89660510d06bbf7691f5296daae36872d697a88876c53db7de91aa85df4f68b

    }

推荐答案

我能够使用以下脚本完成此任务:

i was able to get it done with the below script:

SSID_TO_DELETE=$1 
sed -n "1 !H 1 h $ { x s/[[:space:]]*network={\n[[:space:]]*ssid=\"${SSID_TO_DELETE}\"[^}]*}//g p }" /etc/wpa_supplicant/wpa_supplicant.conf > /etc/wpa_supplicant/wpa_supplicant.conf
