2000XP command line runs multiple commands

xiaoxiao2021-03-06  104

Like the popular Unix Shell, XP command line can use && and || combination of two commands, in order to perform, for example:

AA && BB

It is to perform AA, and then execute BB after success.

AA || BB

Execute AA first, if it is successful, BB is no longer executed, and BB is executed if it fails.

Return Value Errorlevel = 0 indicates that the command you sent is successful.
