Bye bye Bash

Finally got rid of my backup script written in Bash and replaced it with a Python one. I have enough trouble dealing with Bash and I am not looking forward to use it again. Influenced by a passionate crowd, I started working with Linux enthusiastically one year ago. I came around to learn everything about Linux, Vi, Bash, anticipating that they would be great solution to many computing problems.

One of my project was to build a simple backup script using Bash and tar. I started to encounter problem in very basic operations. Thanks for the way Bash does globbing, I cannot easily specify file pattern for files under subdirectories. Tar has its own quirk that I have to hack with 3 different configuration files to setup an inclusion and exclusion list. I finally come to a revelation that should be obvious in retrospect, that many of 30 years old design around Unix are just archaic, difficult to use and error prone. I ditched Bash for a more modern Python. I am very happy since for the easy XML configuration and maintainability.

The lesson learned? Watch out for zealotries. Take their opinion with a grain of salt. They tend to oversold the upside and downplay any problem. Always discern things with critical eyes. This also applies many other areas to such as political opinions.
