我想编辑特定文件的文本

Question

我想修改配置文件，如下图。作为 shell 脚本我可以做什么？

前

Section "InputClass"
        Identifier      "calibration"
        MatchProduct    "Touch"
        Option  "Calibration"   "166 3939 186 3814"
        Option  "SwapAxes"      "1"
        Option  "InvertX"   "on"
        Option  "InvertY"   "on"
EndSection

后

Section "InputClass"
        Identifier      "calibration"
        MatchProduct    "Touch"
        Option  "Calibration"   "166 3939 186 3814"
        Option  "SwapAxes"      "1"
        Option  "InvertX"   "off"
        Option  "InvertY"   "on"
EndSection

甚至

sed -i '/InvertX/s/"on"/"off"/' file_name
