DOS批处理 & 脚本技术（批处理室） » How to check at once whether any of multiple strings exists in a file

There are N strings used as signatures A file may contain these N strings. How can I determine whether the file contains "any one" of these strings? Running "find string file" one by one is too slow. If there are too many signatures, the speed is very slow sed -e '/AAA/b' -e '/BBB/b' -e '/CCC/b' -e d test.txt&& echo %time% This command can search multiple strings at once, but from the returned result I can't tell whether it contains the strings Even if the file does not contain these strings it still shows %time% the same way, so how should this be written? Are there any other tools that can do this? :)

Put the strings to search below sed.ini: AAA BBB CCC findstr /g:sed.ini YourFileToSearch

@echo off&setlocal EnableDelayedExpansion set xs=0 set "var=sed -e "{s/aaa//;s/bbb//;s/ccc//g}" a.txt" for /f "tokens=1* delims=:" %%a in ('findstr /n .* a.txt') do set num%%a=%%b for /f "delims=" %%a in ('%var%') do ( set /a str+=1 call set uew=%%num!str!%% if "!uew!"=="%%a" set /a xs=1 ) echo There are !xs! lines containing the specified strings. pause

Looks like I can only run sed 3 times. Not sure about the efficiency Each time replacing one string.

The problem has been solved, this thread can be closed egrep.exe can support searching multiple strings at the same time, using \| to separate the strings And it returns %errorlevel% correctly
