Fundamentals of UNIX Lab 5.4.6 – Listing Directory Information (Estimated Time: 30 Min.)
Fundamentals of UNIX Lab 5.4.6 – Listing Directory Information (Estimated time: 30 min.) Objectives: • Learn to display directory and file information • Use the ls (list files) command with various options • Display hidden files • Display files and file types • Examine and interpret the results of a long file listing • List individual directories • List directories recursively Background: In this lab, the student will use the ls command, which is used to display the contents of a directory. This command will display a listing of all files and directories within the current directory or specified directory or directories. If no pathname is given as an argument, ls will display the contents of the current directory. The ls command will list any subdirectories and files that are in the current working directory if a pathname is specified. The ls command will also default to a wide listing and display only file and directory names. There are many options that can be used with the ls command, which makes this command one of the more flexible and useful UNIX commands. Command Format: ls [-option(s)] [pathname[s]] Tools / Preparation: a) Before starting this lab, the student should review Chapter 5, Section 4 – Listing Directory Contents b) The student will need the following: 1. A login user ID, for example user2, and a password assigned by their instructor. 2. A computer running the UNIX operating system with CDE. 3. Networked computers in classroom. Notes: 1 - 5 Fundamentals UNIX 2.0—-Lab 5.4.6 Copyright 2002, Cisco Systems, Inc. Use the diagram of the sample Class File system directory tree to assist with this lab. -

What is the impact of COVID-19 on the right to health of persons with disabilities? 2. What is the impact of COVID-19 on persons with disabilities who are living in institutions? 3. What is the impact of COVID-19 on the right of persons with disabilities to live in the community? 4. What is the impact of COVID-19 on work, income and livelihood of persons with disabilities? 5. What is the impact of COVID-19 on the right to education of persons with disabilities? 6. What is the impact of COVID-19 on the right of persons with disabilities to protection from violence? 7. What is the impact of COVID-19 on specific population groups in which persons with disabilities are overrepresented? a. prisoners with disabilities b. persons with disabilities without adequate housing OVERVIEW While the COVID-19 pandemic threatens all members of society, persons with disabilities are disproportionately impacted due to attitudinal, environmental and institutional barriers that are reproduced in the COVID-19 response. Many persons with disabilities have pre-existing health conditions that make them more susceptible to contracting the virus, experiencing more severe symptoms upon infection, leading to elevated levels of death. During the COVID-19 crisis, persons with disabilities who are dependent on support for their daily living may find themselves isolated and unable to survive during lockdown measures, while those living in institutions are particularly vulnerable, as evidenced by the overwhelming numbers of deaths in residential care homes and psychiatric facilities. -

Utmp, Wtmp, Sulog
utmp, wtmp, sulog lastlog File UNIX records the last time that each user logged into the system in the lastlog log file. This time is displayed each time that you log in: e.g. login: grossman password: Last login Mon Feb 14 09:19 on console Unfortunately, the design of the lastlog mechanism is such that the previous contents of the file are overwritten at each login. As a result, if a user is inattentive for even a moment or if the login message clears the screen, the user may not notice a suspicious time. Furthermore, even if a suspicious time is noted, it is no longer available for the system administrator to examine. utmp, wtmp, utmpx, and wtmpx Files UNIX keeps track of who is currently logged into the system with a special file called utmp, or utmpx on Solaris systems. This is a binary file that contains a record for every active session and generally does not grow to be more than a few kilobytes in length. A second file, wtmpx, keeps a record of both logins and logouts. This file grows every time a user logs in or logs out and can grow to be many megabytes in length unless it is pruned. utmpx and wtmpx are found in /var/adm on our Solaris systems. utmp and wtmp do not exist in Solaris. The extended wtmpx file used by the Solaris operating system includes the following: Username, 32 characters instead of 8 inittab ID, indicates the type of connection Terminal name, 32 characters instead of 8 Device name Process ID of the login shell Code that denotes the type of entry Exit status of the process Time that the entry was made Session ID Unused bytes for future expansion Remote hostname for logins that originate over a network Examining the utmpx and wtmpx Files UNIX programs that report the users that are currently logged into the system, e.g. -
The Evolution of the Unix Time-Sharing System*
The Evolution of the Unix Time-sharing System* Dennis M. Ritchie Bell Laboratories, Murray Hill, NJ, 07974 ABSTRACT This paper presents a brief history of the early development of the Unix operating system. It concentrates on the evolution of the file system, the process-control mechanism, and the idea of pipelined commands. Some attention is paid to social conditions during the development of the system. NOTE: *This paper was first presented at the Language Design and Programming Methodology conference at Sydney, Australia, September 1979. The conference proceedings were published as Lecture Notes in Computer Science #79: Language Design and Programming Methodology, Springer-Verlag, 1980. This rendition is based on a reprinted version appearing in AT&T Bell Laboratories Technical Journal 63 No. 6 Part 2, October 1984, pp. 1577-93. Introduction During the past few years, the Unix operating system has come into wide use, so wide that its very name has become a trademark of Bell Laboratories. Its important characteristics have become known to many people. It has suffered much rewriting and tinkering since the first publication describing it in 1974 [1], but few fundamental changes. However, Unix was born in 1969 not 1974, and the account of its development makes a little-known and perhaps instructive story. This paper presents a technical and social history of the evolution of the system. Origins For computer science at Bell Laboratories, the period 1968-1969 was somewhat unsettled. The main reason for this was the slow, though clearly inevitable, withdrawal of the Labs from the Multics project. To the Labs computing community as a whole, the problem was the increasing obviousness of the failure of Multics to deliver promptly any sort of usable system, let alone the panacea envisioned earlier.
