CIS3110 Operating Systems Winter 2021 Assignment 4: File System Reports This assignment asks you to generate reports (to STDOUT) about the file system that display information about the files and directories that appear in a directory that you have supplied to your program as a command line argument. Your program will be called FSreport and will take 2 arguments: - First argument is the type of report to be generated o -tree for tree directory structure format o -inode for inode format - Second argument is the full path name of the root directory (where the descriptions will start) Example: $ ./FSreport -tree /home/myname/rootDir You will use the fstat or stat command to retrieve information about the files and opendir and other related functions for information about directories. Your report can have 2 forms: Tree directory structure (-tree) - Sorted alphabetically by file/directory name - For each file/directory display the following: o Line 1: owner name (group name), inode number, permissions, size in bytes, file/directory name o Line 2: Date of last access, Date of last modification (to data or status whichever is most recent) - Each sub-directory in the file systems tree structure (starting with the given root directory) should be explored. - Indicate in your README if you can only report on the files/directories in the root directory (one level only) or if you can display multiple sub-directory levels (indicate the number of levels or the fact that your code can handle any number of levels). An example of this type of report is in Example A. Inodes Format (-inode) - Sorted by inode number – smallest to largest - For each file/directory display the following: o Inode number: size (in bytes), number of 512-byte blocks allocated to the file, file size/512, file/directory name An example of this type of report is in Example B. The following examples are reporting on the directory structure in the following diagram: Level 1 is Assignment4 (you would have specified its entire pathname as a command line argument. Level 2 are the contents of the sub-directories Javascript and subDirA.
