[文本处理] 查找字符所在行，并在找到的行尾添加字符

zhoubin

如题：
在批处理卸载.cmd中，查找字符del %0 >NUL 2>NUL&cd ..&rd "%~dp0" >NUL 2>NUL&if not exist "%cd%\*" reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Folders" /f /v "C:\\Program Files\\Icsoft\\"

并在找到的行，行尾添加& reg delete "HKU\S-1-5-21-2955475268-2234008017-1310366641-1000\Software\Icsoft" /f

添加后的卸载.cmd效果del %0 >NUL 2>NUL&cd ..&rd "%~dp0" >NUL 2>NUL&if not exist "%cd%\*" reg delete "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Folders" /f /v "C:\\Program Files\\Icsoft\\" & reg delete "HKU\S-1-5-21-2955475268-2234008017-1310366641-1000\Software\Icsoft" /f
