Searching for a string within a text file

[yankfootball]

I am building a batch file that would only call another batchfile if a certain text string is found within a particular text file:  I was thinking I could use the IF, FINDSTR and CALL commands to build this but since my DOS knowledge is limited at best I am unsure of the syntax.



For example

Execute batch file "A"

IF FINDSTR /I "Database" file.txt CALL B.bat. ELSE CALL C.bat.


anyhelp would be appreciated..

You can do:

Code: [Select]

FINDSTR /I file.txt "Database" > NUL
if not errorlevel 1 (CALL B.bat) ELSE CALL C.bat
The command FIND/FINDSTR return an errorlevel equal to 0 when the string is found in the file.
The most of the commands return an errorlevel 0 when they are correctly executed.

The sentence:
      IF ERRORLEVEL 5 command
would be equivalent to
       IF ERRORLEVEL >= 5 command    <-- you can't do this

so, if you negate:

      IF NOT ERRORLEVEL 5 command
is equivalent to
      IF ERRORLEVEL < 5 command

and ...

      IF ERRORLEVEL 5 IF NOT ERRORLEVEL 6 command[/tt][/color]
is equivalent to
      IF ERRORLEVEL == 5 command
