How was I called?

Is there a way for a batch file to know whether it was called from a command window or from within another batch file?
I have a script that should prompt if run "interactively" or not prompt if "call"ed from a within another batch file.
Thanks!

Hi bowler,
I dont know a way to detect this.
But perhaps you can use simple a special start parameter for the batch file,
if it is calling from another batch file.
Command Line parameters

Use a command line parameter from the first batch and check for it in the second batch
eg one batch calls another
1stbatch.bat contains
IF blah blah blah DO START /wait 2ndbatch.bat called
2ndbatch.bat contains
IF "%1"=="called" GOTO blah blah blah
If 2ndbatch.bat is run on its own without a parameter then it will fail the if statement.

I was hoping to avoid passing yet another parameter as the called procedure already has up to 5 different params.
Oh well...

Hi bbowler,
you can try to use %0
if you start the batch (doIt.bat) from command line
like doIt or doIt.bat you get doIt or doIt.bat
if you call it from another batch call it like doIt.BaT
So you can simple decide by the case of "BaT" how it is called.
Not perfect, but perhaps better than the "parameter way".

You could start the 2nd batch in the first batch like this:
SET called=1
call 2ndbatch.baT
2ndbatch.bat
IF called=1 then bleh
otherwise it was ran from the cmd prompt.
Last line in 2ndbatch:
set called=0

What jep is suggesting is:
Code: Select all
@echo off
set "me=%~0"
if "%me:~-4%"==".baT" (
echo.%~0 called from within batch
GOTO:EOF
)
echo.%~0 called from elsewhere
myWhoCalled.baT
Output:
myWhoCalled called from elsewhere
myWhoCalled.baT called from within batch
Enjoy
