how to make the batch file wait until another batch file completes execution?

Question

how to make the batch file wait until another batch file completes execution?

let me explain with an example.

echo hi >r.txt
echo some piece of code >>r.txt 

start ar.bat

echo some piece of coe >>ar.txt 

i want the code after start ar.bat to execute after this batch file exits ..

i have tried without start it works but i want to run it in a seperate window ..is there any function to check whether that window which is running ar.bat is present ?

Answer 1

Use call ar.bat to do it completely with batch file commands.

Use start /wait ar.bat to get another window and wait for it to complete.
