Create File comparators that arrange files in ascending/descending order of file size, ascending/descending order of file name, and ascending/descending order of last modification date. Employ these comparators in LS, a programme that accepts a command-line input and lists the files in the current directory in a certain order, such as "-t" to sort by timestamp.To break ties, support several flags. Be certain you use a reliable sort.
With linked allocation, each file is a linked list of disk blocks; the disk blocks may be scattered anywhereon the disk. The directory contains a pointer to the first and last blocks of the file. Each block contains a pointerto the next block. Refer to the illustration below.
