Answer 2

(c)  mkdir -p

Explanation:

• mkdir dirname, it creates a directory in the current location
• mkdir {dir1,dir2,dir3,dir4}, it creates multiple directories in the current location. Do not use spaces inside {}
• mkdir –p, it creates directory/path/newdirectory Create directory structure including missing parent directory (if any)
• mkdir –m777 dirname , it creates directory and set full read, write and execute permissions for everyone
• mkdir –v dirname(s) , it creates a directory in the current location.
• All  dimension members in a parent-child hierarchy reside in one logical column, as opposed to level-based hierarchies.
• In a parent-child hierarchy, a member's parent  is in a different row in the same logical column pointed to by the parent key. This differs from level-based hierarchies, where members have parents in  different logical columns of the same row. In other words, navigation in parent-child hierarchies follows data values, but navigation in  level-based hierarchies follows  metadata structure.
