I am in a directory in windows command prompt. I can create one sub-directory in a single command like the following: md /data/rs1. I also can create multiple sub-directories by a single command from Linux like: mkdir -p /data/rs1 /data/rs2 /data/rs3. But I want to create multiple sub-directories in windows command prompt by a single command.
What Is Certified Mail? Certified mail is a service provided by the United States Postal Service in which the sender of an envelope or package receives a proof of delivery postcard after the item has been delivered, signed by the recipient. The postcard includes the date and time.
Best Answer: A certified letter is sent by a person or a business when they want to mail important information and be sure that it was received. It's not usually a good thing. Collection agencies send them, people involved in legal cases send them, etc... certified letter is one where the post office ensures that the letter is only delivered to the person it was addressed to, and records his signature.
