Problem:

Being a new, need to get clear idea about the command to create directory?
You need to create the directory /var/oracle/database/9i. Only the directory /var currently exists. From the root of the filesystem, which command will create the directory path?
  • md -path /var/oracle/database/9i
  • mkdir /var/oracle/database/9i
  • mkd /var/oracle/database/9i
  • mkdir -p /var/oracle/database/9i
