Batch file: Find if substring is in string (not in a file) Part 2 - Using Variables

Question

In a Windows batch file, I have a string 'abcdefg'. I want to check if 'bcd' is in the string, but I also want each to be in a variable, or pass in a parameter for the string.

This solution comes close, but uses constants rather than variables. Batch file: Find if substring is in string (not in a file)

Solution 1

try one:

set "var=abcdefg"
set "search=bcd"
CALL set "test=%%var:%search%=%%"
if "%test%"=="%var%" (echo %search% is not in %var%) else echo %search% in %var% found

set "var=abcdefg"
set "search=bcd"
echo %var%|findstr /lic:"%search%" >nul && echo %search% found || echo %search% not found

Solution 2

The solution is to use FindStr and the NULL redirect, >nul.

SET var=%1
SET searchVal=Tomcat
SET var|FINDSTR /b "var="|FINDSTR /i %searchVal% >nul
IF ERRORLEVEL 1 (echo It does't contain Tomcat) ELSE (echo It contains Tomcat)

Save as test.bat and execute with the parameter to be searched, as follows: test Tomcat7

C:\>test Tomcat9
It contains Tomcat

The second answer here helped me out, I had square brackets in the string and managed to get things working with this answer.
