2 likes•939 views
This document provides an overview of key data types and concepts in Perl, including scalars, arrays, hashes, code, input/output handling, and packages. It discusses how scalars can represent numbers, strings, and references, and how arrays and hashes store lists of scalars. It also covers defining and calling anonymous functions, opening files, and using packages to organize namespaces and variables. Globals and lexically scoped variables are compared, and the concept of closures is introduced by example.

- Finally, it provides an overview of classes, objects, inheritance and unit testing in Perl.
Unix lab manual
The document discusses various Unix/Linux commands for text processing and file management. It describes the commands head, tail, tr, sort, cut, uniq, diff, tee, find, and grep. Head displays the first few lines of a file, tail displays the last few lines, and tr translates or deletes characters. Sort sorts the lines of a text file, cut removes sections from each line, and uniq removes duplicate lines from a sorted file. Diff finds differences between two files.
Unix 1st sem lab programs a - VTU Karnataka
This document contains code for several shell scripting exercises:
1. Lab1a accepts command line arguments and prints them in reverse order.
2. Lab1b checks if two file permissions are identical, printing the common permission or each file's individual permissions.
3. Lab2b creates all directories in a path if they don't exist.
4. Lab9b counts and reports the occurrences of words from the first argument file that are present in other argument files.
Logrotate sh
This document is the source code for the logrotate utility. It summarizes the logrotate program as rotating log files by compressing or removing old log files based on options in a configuration file. Key sections of code handle parsing command line arguments, reading options from a configuration file, and implementing the core rotation logic on individual log files.
spug_2008-08
This document describes using the File::Find and MP3::Tag modules in Perl to search directories of MP3 files, find duplicates, and extract metadata. It starts by explaining how File::Find searches directories and calls a callback subroutine. It then shows incrementally building a script that uses File::Find to search for MP3 files, uses MP3::Tag to extract metadata, stores it in a database, and finds duplicate songs based on normalized artist/title fields. Security techniques like taint mode and untainting are also demonstrated to safeguard against malicious file paths.
Making a simple jQuery plug-in
The document provides steps for creating a simple jQuery plugin. It discusses creating a file for the plugin, making a closure, defining the jQuery command, returning the jQuery wrapped set, setting up an options hash, using private methods, and allowing events to be customized via the options hash. The plugin created in the example is called "spock" and finds and wraps proper nouns in paragraphs with a span.
COSCUP2012: How to write a bash script like the python?
This document discusses how to write bash scripts similar to Python scripts by using functions, modules, and documentation strings (docstrings). It explains that bash functions allow for logic, reuse, and unit testing like Python. It demonstrates how to define bash functions, import them as modules, and add docstrings. While bash can mimic some Python features, it has limitations compared to Python for things like namespaces and cannot work with all shells like busybox ash.
Perl Basics for Pentesters Part 1
This document provides an introduction to the Perl programming language for pentesters. It covers fundamental Perl concepts like data types, control structures, loops, functions, file handling and special variables. The document is split into two parts, with the first part focusing on basics and the second part covering more advanced topics like regular expressions, useful modules, and example Perl scripts for pentesting. It also mentions that a future section will demonstrate tools like dnsenum, fierce, nikto and sqlninja.

http://www.zyxware.com/articles/3080/zyxware-conducts-workshop-on-bash-scripting-at-tkm-college-of-engineering-kollamBag of tricks
This document summarizes Brian D Foy's presentation on "My Perl Bag of Tricks" given at YAPC::Brasil 2011. Some of the tricks discussed include eliminating special cases, using Perl to do more of the work, scaling code gracefully, parsing XML data efficiently, testing code with sample inputs/outputs, and handling errors gracefully. The presentation aims to show Perl techniques for writing cleaner, more robust code.

Parsing JSON with a single regex
The document discusses parsing JSON with a single regular expression in Perl. It describes using grammars, recursion, and code execution within the regex to build a data structure that is returned. Key features include using (?&NAME) to recurse on named patterns, (?{ CODE }) to execute code during matching, and $^R to build and return a data structure.
Metadata-driven Testing
Testing with Copy+Paste is ineffective. Metadata at multiple levels of the test from its name to contents allow more complete testing with less code.
Hypers and Gathers and Takes! Oh my!
The document discusses processing large sequence data files in parallel using Raku. It describes reading input sequences from files in fixed-size chunks, passing the chunks to worker threads for processing, and using techniques like gather/take and lazy evaluation to improve performance over alternative approaches. The key steps are:
1. Read the input file in chunks and pass chunks to worker threads for parallel processing.
2. Use gather/take and lazy evaluation to improve throughput over alternatives like forking processes or using channels that introduce overhead.
3. SHA sequences in parallel to detect duplicates while avoiding memory issues from comparing all pairs directly.
Talk Unix Shell Script 1
The document discusses UNIX shell scripts, including what they are, their components, how to invoke them, examples of arguments, variables, command forms, and simple commands that can be used in shell scripts.

Pollock and Snow "DEIA in the Scholarly Landscape, Session One: Setting Expec...National Information Standards Organization (NISO)
This presentation was provided by Steph Pollock of The American Psychological Association’s Journals Program, and Damita Snow, of The American Society of Civil Engineers (ASCE), for the initial session of NISO's 2024 Training Series "DEIA in the Scholarly Landscape." Session One: 'Setting Expectations: a DEIA Primer,' was held June 6, 2024.A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
