[文本处理] [分享]批处理在文本第三行添加指定内容

Batcher

【问题描述】

Settings.ini内容如下：

[/Script/Engine.GameUserSettings]
bUseDesiredScreenHeight=False

[ScalabilityGroups]
sg.ResolutionQuality=100.000000
sg.ViewDistanceQuality=0
sg.AntiAliasingQuality=0
sg.ShadowQuality=0
sg.PostProcessQuality=0
sg.TextureQuality=0
sg.EffectsQuality=0
sg.FoliageQuality=0

需要在第二行下面添加一行：
GraphicsAPI=DX11_Enhanced

方案4 使用命令行工具 sed.exe

sed "3iGraphicsAPI=DX11_Enhanced" "Settings.ini" > "Settings_New.ini"
