Starting random batch file from a certain folder

Question

Problem is this, I have one folder named \"abc\" with several batch files and they are named like this:

abc1.bat
abc2.bat
abc3.bat
abc4

Answer 1

Say 1000 is the number of your abcX.bat files. Then this will do the trick:

SET /a rand=%RANDOM%*1000/32768+1
CALL abc%rand%.bat
