Introduced/ dev/shm/ is a device that uses the Tmpfs file system, which is actually a special file system. the default size in Redhat is half of physical memory, so that time is not mkfs formatted. TMPFS is a memory-based virtual file system on the Linux/unix system .TMPFS can use your memory or swap partition to store the file ( that is, its storage space in virtual memory , the VM consists of real memory and swap ). Thus, TMPFS primarily stores s

/dev/zero is a special file in a Unix-like system that provides an infinite null character when the file is read. One of its main uses is to provide a character stream to initialize the data store, which is to overwrite the target data with a null character.
