data extraction

In the realm of programming and data analysis, manipulating JSON data effectively can be a critical task. While there are powerful tools like jq designed specifically for handling JSON, sometimes you might need to extract JSON values directly within a Bash script without using external tools. Today, we're exploring how to leverage the grep command, specifically grep -oP, to extract values from JSON data. A1: The grep command is traditionally used in UNIX and Linux environments to search for patterns in files. The -o flag tells grep to only return the part of the line that matches the pattern. The -P flag enables Perl-compatible regular expressions (PCRE), which offer more powerful pattern matching capabilities.

In today’s world, where data is ubiquitous and its analysis vital, the realms of web development and system administration are increasingly overlapping with artificial intelligence (AI). One interesting area of AI that can be particularly useful for handling and analyzing text data is Named Entity Recognition (NER). NER refers to the process of identifying and classifying key elements in text into predefined categories such as the names of people, organizations, locations, expressions of times, quantities, monetary values, percentages, etc. This blog aims to provide a comprehensive guide for full stack web developers and system administrators looking to expand their AI knowledge, specifically through using Bash for simple NER tasks.

Logs serve as a window into the operations of an application or system and are crucial for troubleshooting issues and optimizing performance. For system administrators and developers working on Linux, mastering log parsing and data extraction is essential. This article explores some effective techniques and tools you can use to parse logs and extract useful information on a Linux system. Log files in Linux are typically stored in the /var/log directory. Files located here can include system logs (syslog), authentication logs (auth.log), web server logs, and logs from various installed applications. Depending on the Linux distribution and the specific application, the exact naming and rotation scheme of log files may vary.
