  • Program #6: Word Count

    Program #6: Word Count

    CSc 227 — Program Design and Development Spring 2014 (McCann) http://www.cs.arizona.edu/classes/cs227/spring14/ Program #6: Word Count Due Date: March 11 th, 2014, at 9:00 p.m. MST Overview: The UNIX operating system (and its variants, of which Linux is one) includes quite a few useful utility programs. One of those is wc, which is short for Word Count. The purpose of wc is to give users an easy way to determine the size of a text file in terms of the number of lines, words, and bytes it contains. (It can do a bit more, but that’s all of the functionality that we are concerned with for this assignment.) Counting lines is done by looking for “end of line” characters (\n (ASCII 10) for UNIX text files, or the pair \r\n (ASCII 13 and 10) for Windows/DOS text files). Counting words is also straight–forward: Any sequence of characters not interrupted by “whitespace” (spaces, tabs, end–of–line characters) is a word. Of course, whitespace characters are characters, and need to be counted as such. A problem with wc is that it generates a very minimal output format. Here’s an example of what wc produces on a Linux system when asked to count the content of a pair of files; we can do better! $ wc prog6a.dat prog6b.dat 2 6 38 prog6a.dat 32 321 1883 prog6b.dat 34 327 1921 total Assignment: Write a Java program (completely documented according to the class documentation guidelines, of course) that counts lines, words, and bytes (characters) of text files.

    Unix Security Overview: 1

    CIS/CSE 643: Computer Security (Syracuse University) Unix Security Overview: 1 Unix Security Overview 1 User and Group • Users – root: super user (uid = 0) – daemon: handle networks. – nobody: owns no files, used as a default user for unprivileged operations. ∗ Web browser can run with this mode. – User needs to log in with a password. The encrypted password is stored in /etc/shadow. – User information is stored in /etc/passwd, the place that was used to store passwords (not anymore). The following is an example of an entry in this file. john:x:30000:40000:John Doe:/home/john:/usr/local/bin/tcsh • Groups – Sometimes, it is more convenient if we can assign permissions to a group of users, i.e. we would like to assign permission based on groups. – A user has a primary group (listed in /etc/passwd), and this is the one associated to the files the user created. – Any user can be a member of multiple groups. – Group member information is stored in /etc/group % groups uid (display the groups that uid belongs to) – For systems that use NIS (Network Information Service), originally called Yellow Page (YP), we can get the group information using the command ypcat. % ypcat group (can display all the groups and their members) 2 File Permissions • File Permissions – The meaning of the permission bits in Unix. ∗ Owner (u), Group (g), and Others (o). ∗ Readable (r), Writable (w), and Executable (x). ∗ Example: -rwxrwxrwx (777) • Permissions on Directories: – r: the directory can be listed. – w: can create/delete a file or a directory within the directory.

  • Unique Identifier for Staff (UID Staff) Overview

    Unique Identifier for Staff (UID Staff) Overview

    Unique Identifier for Staff (UID Staff) Overview The intent of this document is to provide an overview of the Unique Identifier for Staff (UID Staff) system prior to working in the UID Staff System. After reviewing this information, please review the training materials that are available on the UID Staff Training website (http://www.ncpublicschools.org/cedars/uniqueid/staff/training/) for instructions on how to complete the processes of the Staff UID System. Staff UID Overview • The Unique Identifier for Staff System (UID Staff) will assign a unique identifier to Staff who participate in the North Carolina public school system. • Unique IDs follow staff between school districts and remain valid even if they move out of state and then return to a NC public school. • Assigning unique identifiers is the first step in DPI’s multi-stage effort to create the NC Common Education Data Analysis and Reporting System (CEDARS). • UID Staff is built on the eScholar Uniq-ID® for Staff product. Overview of UID Staff Process The UID Staff process includes the following 8 steps: 1. Generate CEDARS Staff file from LEA/Charter School Payroll System • Instructions for generating this file can be found at: http://www.ncpublicschools.org/docs/cedars/uniqueid/staff/training/creating-extracts.pdf 2. Upload CEDARS Staff file into UID Staff and Initiates Data Validation • This file can be loaded into the Training Environment (https://cedarstrain.schools.nc.gov/staffid/) so that you can check for errors before loading into production. 3. Download Fix Errors Report (if data errors are found by the UID Staff System) 4.
