Waiting until a process created by calling a batch file has completed

Question

MyFile1.bat invokes MyFile2.bat twice:

start MyFile2.bat argA, argB, argC
start MyFile2.bat argX, argY, argZ

At this point, how can I wait until both processes spawned by the calls to MyFile2.bat have completed?

Answer 1

Simple use the Start /WAIT parameter.

start /wait MyFile2.bat argA, argB, argC
start /wait MyFile2.bat argX, argY, argZ

Answer 2

start /w cmd /c "start cmd /c MyFile2.bat argA, argB, argC & start cmd /c MyFile2.bat argA, argB, argCt"

According to my tests this should work providing that the MyFile2.bat .Eventually the full paths to the bat files should be used.
