Question

请帮助语法查找字符串以搜索带字符串的paragrah开头并以另一个字符串结束。例如：支持成功处理成员ID为1234的文件。在这里，我想搜索某些行以成员开头，并以成功处理结束。这里我使用下面的代码（供参考）。请告诉我任何困惑

for /f "delims=" %%A in ('
findstr /B "member " /E "processed successfully." abc.log
') do set "check=True"

Answer 1

Findstr command使用正则表达式（搜索文本模式）

 findstr /R "^member\ .*processed\ successfully\.$" abc.log

或没有正则表达式：管道findstr输出到另一个findstr，如下所示：

 findstr /B /C:"member " abc.log | findstr /E /C:"processed successfully."

注意：如果在for /F loop中使用|管道字符，则需要对管道命令的结果进行转义，如下所示：

for /f "delims=" %%A in ('
     findstr /B /C:"member " abc.log ^| findstr /E /C:"processed successfully."
') do set "check=True"

正则表达式：FINDSTR对正则表达式的支持是有限且非标准的，只有以下元字符是支持：

 .         Wildcard: any character

 *         Repeat: zero or more occurances of previous character or class

 ^         Line position: beginning of line
 $         Line position: end of line

 [class]   Character class: any one character in set
 [^class]  Inverse class: any one character not in set

 [x-y]     Range: any characters within the specified range

 \x        Escape: literal use of metacharacter x

 \<xyz     Word position: beginning of
 xyz\>     Word position: end of word

如何批量处理findstr来搜索起始char和结束char
