Unlike many other languages, we can add or remove elements to and from Bash arrays. However, the usual removal process leaves a hole at the original position, making it a sparse array. In this tutorial,we’ll learn how to completely remove an element from a Bash array. 2. Understanding t...

Using the snippets from this bible can help remove unneeded dependencies from scripts and in most cases make them faster. I came across these tips and discovered a few while developing neofetch, pxltrm and other smaller projects.The snippets below are linted using shellcheck and tests have been ...

这本书的目的是汇总只使用内置bash的特性来实现总所周知和鲜为人知的各项任务。 使用此参考书中的代码段可以帮助你从脚本中删除不需要的依赖项,并且在大多数情况下可以使它们运行的更快。 我偶然碰到了这些技巧并在开发neofetch,pxltrm和一些其他小的项目的时候发现了一些别的技巧。
