Question

我只想在file1.txt中包含file2.txt中不存在的其他行时才从file1.txt复制到file2.txt。

说，file1.txt如下所示。

*createbutton(5,5,0,6,BUTTON,"",EvalTcl,"Bolt.tcl")
*createbutton(5,"Help",5,6,4,BUTTON,"",EvalTcl,"help.tcl")
*createbutton(5,newline)

和file2.txt如下

*createbutton(5,5,0,6,BUTTON,"",EvalTcl,"Bolt.tcl")
*createbutton(5,"Help",5,6,4,BUTTON,"",EvalTcl,"help.tcl")

然后它应该只复制file1.txt中的第3行，即..＆＃34; * createbutton（5，newline）＆＃34;到file2.txt，因为file2.txt中已存在前2行。

我希望我明白我的要求。欢迎任何帮助。

谢谢你，问候， Prasad Poduval

Answer 1

您所描述的内容基本上与diff utility完全相同。

Answer 2

@ECHO OFF
SETLOCAL
FOR /f "delims=" %%a IN ('type q25162700_1.txt^|findstr /g:q25162700_2.txt /v ') DO (
 >>q25162700_2.txt ECHO %%a
)

GOTO :EOF

我使用了包含您的数据的q25162700_1.txt和q25162700_2.txt文件进行测试。
