**This programming assignment is for use in the LINUX/UNIX environment!!

Introduction:
System administration often requires custom written programs and tools. One problem a system admin faces is deleting oversized files on the system.

Assignment Description:
This assignment is to write a program to find files that exceed a given threshold in size. This tool will allow the system admin to find those files that are dominating the usage of the file system.

Program Requirements:
1) The program will take 2 arguments, an options argument and a size argument.
2) The size argument is a number representing the threshold size. For example, if 10 is entered, it will find all files larger than 10 megabytes.
3) The options are to be as follows:
1. -f (this option will display the file name
2. -s (this option will calculate the summary of all file sizes)
3. -t (this option will display the total summary only.
These arguments may be entered in single option fashion or multiple. Example:

$filesize -sf 10

-This will display all files over 10 megabytes and include a summary of all files sizes.
The output is as follows:

80 /home/smith/Tools/decode.tgz
28 /home/smith/Tools/parse_code.a

**NOTE: that decode.tgz is 80 MB and parse_code.a is 28 MB.

4) The program will take the file list in as a stream from the standard input. The "find" command will be used to create the stream, but no options will be allowed to be used.
The "find" command is used here as a simplifying element of the program.
5) The program will use the "stat" system call to filter out dir/block/link/socket files and only return "regular" files.
6) The program will use the "stat" system call to get the file size.



SAMPLE CODE THAT CAN BE USED (You Don''t HAVE to use this):

For POSIX environment:

struct stat sb;
int result = 1; /* result */
if (msg) msg[0] = ''\0'';
if (stat(FN,&sb) == 0) {
if (S_ISDIR (sb)) result = 0;
else if (S_ISFIFO(sb)) result = 0;
else if (S_ISBLK (sb)) result = 0;
else if (S_ISSOCK(sb)) result = 0;
}
}
