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.

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. -

January 22, 2021. OFLC Announces Plan for Reissuing Certain Prevailing Wage Determinations Issued under the Department’s Interim Final Rule of October 8, 2020; Compliance with the District Court’s Modified Order. On January 20, 2021, the U.S. District Court for the District of Columbia in Purdue University, et al. v. Scalia, et al. (No. 20-cv-3006) and Stellar IT, Inc., et al. v. Scalia, et al. (No. 20-cv- 3175) issued a modified order governing the manner and schedule in which the Office of Foreign Labor Certification (OFLC) will reissue certain prevailing wage determinations (PWDs) that were issued from October 8, 2020 through December 4, 2020, under the wage methodology for the Interim Final Rule (IFR), Strengthening Wage Protections for the Temporary and Permanent Employment of Certain Aliens in the United States, 85 FR 63872 (Oct. 8, 2020). The Department is taking necessary steps to comply with the modified order issued by the District Court. Accordingly, OFLC will be reissuing certain PWDs issued under the Department’s IFR in two phases. Employers that have already submitted a request in response to the December 3, 2020 announcement posted by OFLC have been issued a PWD and do not need to resubmit a second request for reissuance or take other additional action. PHASE I: High Priority PWDs Within 15 working days of receiving the requested list of named Purdue Plaintiffs and Associational Purdue Plaintiffs from Plaintiffs’ counsel, OFLC will reissue all PWDs that have not yet been used in the filing of a Labor Condition Application (LCA) or PERM application as of January 20, 2021, and that fall into one or more of the following categories: 1. -
The UNIX Time- Sharing System
1. Introduction There have been three versions of UNIX. The earliest version (circa 1969–70) ran on the Digital Equipment Cor- poration PDP-7 and -9 computers. The second version ran on the unprotected PDP-11/20 computer. This paper describes only the PDP-11/40 and /45 [l] system since it is The UNIX Time- more modern and many of the differences between it and older UNIX systems result from redesign of features found Sharing System to be deficient or lacking. Since PDP-11 UNIX became operational in February Dennis M. Ritchie and Ken Thompson 1971, about 40 installations have been put into service; they Bell Laboratories are generally smaller than the system described here. Most of them are engaged in applications such as the preparation and formatting of patent applications and other textual material, the collection and processing of trouble data from various switching machines within the Bell System, and recording and checking telephone service orders. Our own installation is used mainly for research in operating sys- tems, languages, computer networks, and other topics in computer science, and also for document preparation. UNIX is a general-purpose, multi-user, interactive Perhaps the most important achievement of UNIX is to operating system for the Digital Equipment Corpora- demonstrate that a powerful operating system for interac- tion PDP-11/40 and 11/45 computers. It offers a number tive use need not be expensive either in equipment or in of features seldom found even in larger operating sys- human effort: UNIX can run on hardware costing as little as tems, including: (1) a hierarchical file system incorpo- $40,000, and less than two man years were spent on the rating demountable volumes; (2) compatible file, device, main system software. -

Time-Space Analysis in Programming Languages 109
Time-space analysis in Programming Languages Jatinder Manhas* Abstract Time and space complexity of a program always remain an issue of greater consideration for programmers. The author in this paper has discussed the time and space complexity of a single program written in different languages. The sample program was one by one executed on a single machine with similar configuration in each case with different compiler versions. It has been observed that in different languages (C, C++, Java, C#) time taken varies. Mostly the research done for language in case of time-space trade-off is usually not bounded with fixed system configuration. In that case we calculate the time and space complexity of a particular algorithm with no system constraints. Such procedure does not give us time and space complexity of program with respect to language. The author here believes to calculate the time and space complexity of a program with respect to language. While execution of a sample code written in different Introduction languages on fixed system configuration, for each run of sample code, CPU time is calculated and compared. It In dealing time and space complexity we come up with the shows how the choices of language affect the time and introduction of following elements: space resource. Time and Space Complexity Keywords: Time and space Complexity, Program, Language, Time Complexity, Space Complexity In computer science, the time complexity of an algorithm quantifies the amount of time taken by an algorithm to run as a function of the length of the string representing the input. The time complexity of an algorithm is commonly expressed using big O notation, which excludes coefficients and lower order terms. -

Let SAS® Do Your Dirty Work, Richann Watson
Paper RX-03-2013 Let SAS® Do Your DIRty Work Richann Watson, Experis, Batavia, OH ABSTRACT Making sure you have all the necessary information to replicate a deliverable saved can be a cumbersome task. You want to make sure that all the raw data sets are saved, all the derived data sets, whether they are SDTM or ADaM data sets, are saved and you prefer that the date/time stamps are preserved. Not only do you need the data sets, you also need to keep a copy of all programs that were used to produce the deliverable as well as the corresponding logs when the programs were executed. Any other information that was needed to produce the necessary outputs needs to be saved. All of these needs to be done for each deliverable and it can be easy to overlook a step or some key information. Most people do this process manually and it can be a time-consuming process, so why not let SAS do the work for you? INTRODUCTION Making a copy of all information needed to produce a deliverable is time-consuming and is normally done using Windows® Explorer: copy and paste to a new folder for archiving Command interpreter (CMD shell)*: copy or move commands Both of these methods require you to create an archive directory and either copy or move the files manually. Most people go the route of using Windows Explorer due to familiarity. This can tie up your computer while the files are being archived. CMD is faster and commands can be set to run in the background if you know how to access CMD and know the necessary commands.
