grep op

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.
