Four Reasons that I Sometimes Use Awk Instead of Python

Python is a fantastic language, but in specific situations, Awk can offer significant advantages, particularly in terms of portability, longevity, conciseness, and interoperability.

While Python scripts are generally portable, they may not always run seamlessly on popular Docker base images like Debian and Alpine. In contrast, Awk scripts are often readily available and executable within these environments.

Although Python syntax is relatively stable, its lifespan is shorter compared to Awk. For example, the print 10 syntax from the early 2000s is no longer valid in modern Python. However, Awk scripts from the 1980s can still be executed in current environments.

Python is known for its conciseness, especially when compared to languages like Java. However, when it comes to text processing and working within shell pipelines, Awk often provides more concise solutions. For instance, extracting text blocks between "REPORT" and "END" can be achieved with a single line in Awk: /REPORT/,/END/ { print }. Achieving the same result in Python typically involves more lines of code, including handling file input and pattern matching.

While Python can be embedded within shell scripts like Bash, aligning the indentation of multiline Python code with the surrounding shell script can often break the Python syntax. Awk, on the other hand, is less sensitive to indentation, making it easier to integrate into shell scripts.

Although different Awk implementations (such as Busybox Awk and GNU Awk) may have minor variations, Awk generally offers advantages over Python in the situations mentioned above.
