Browsers are designed to think that Images with same name don’t change rapidly so regularly. This creates a problem in some cases where you have to reuse a specific name Or a specific location for a system.
AWK is a general purpose programming language that is designed for processing text-based data, either in files or data streams, and was created at Bell Labs in the 1970s
I noticed that Erik Wendelin wrote an article “awk is a beautiful tool.” In this article he said that it was best to introduce Awk with practical examples. I totally agree with Erik.
Eric Pement’s Awk one-liner collection consists of five sections:
- 1. File spacing,
- 2. Numbering and calculations,
- 3. Text conversion and substitution,
- 4. Selective printing of certain lines,
- 5. Selective deleting of certain lines.
The first part of the article will explain the first two sections: “File spacing” and “Numbering and calculations.” The second part will explain “Text conversion and substitution”, and the last part “Selective printing/deleting of certain lines.”
