(3 points per one option) The options [-o | -s | -t] are mutually exclusive and if none specified -t default option is assumed
The script accepts a list of directory paths and if none is provided the current path is used.
Option [-h] prints a help similar to this homework descriptions but which is formatted as in other standard Unix utilities
The option should print a section LEGAL NOTICE where you state your nickname (and name)
The option LEGAL NOTICE should also contain license. I encourage you to use Apache 2.0 license.
The options -b, -k, -m, -g determine a unit with which the script is reporting the file size. The default one is -b
-b - the script reports sizes in bytes
-k - the script reports in kilobytes
-m - the script reports sizes in megabytes
-g - the script reports sizes in gigabytes
report only integers, but document how do you round the numbers
For option -t the scripts computes sizes of all files in directory paths but reports the sizes of files only per file of the files.
For finding out the file types it is recommended to use file --mime-type command
For example it will report the total number of pdf files, text files, postscript files in the current directory
For option -o print relative path and sizes of files which were not modified at least one month and also belong to 10% of files under examined directories which are the oldest (were modified the longest time ago).
For option -s the script reports the sizes of directories and files in breadth first (top down) manner.
It first reports the names and sizes of of top-level directories given as arguments
Then it reports sizes and the relative paths to files and directories in the top level directories and so on.
Note that this option may be very computational demanding and nontrivial level of caching precomputed information is expected.
