Batch Files

Attention when calling other batch files

Note that when a windows batch file issues a DOS command it will get back the control when that command finishes execution BUT it does not get the control again if it calls another batch file.

Ex. (incorrect):

dir
someOtherBatchFile.bat
dir

The last "dir" command wont be executed because the batch file wont get the control after "someOtherBatchFile.bat" finishes execution.
The solution is using the call keyword:

Ex. (correct):

dir
call someOtherBatchFile.bat
dir

Variables

Ex.

::text
set someVar=hello
::the current folder
set batchFolder=%CD%
::a folder
set someFolder=C:\Programming\

::access the vars
ECHO %someVar%
cd %batchFolder%
dir
cd %someFolder%
dir

Pause

The pause command will wait for the user to press any key before the batch file proceeds.
Just write "pause" in the batch file.
