Linux Bash - 排除带有find的目录

Question

我正在编写一个当前正在编写的bash脚本时出现问题，并且我已经隔离了有问题的代码。

使用变量中的参数时查找命令不会排除目录。

现在我需要分配＆＃39; -not -path ./dir'变量的参数，因为它被循环，但如果我这样做，它似乎不起作用。

我已经包含了产生所需输出的命令下方，以及我当前打破的版本。请参阅下面的测试：

变量赋值

findIgnorePaths="-not -path ./\.git\* -not -path ./administrator/cache\* -not -path ./images\* -not -path ./logs\* -not -path ./cache\* -not -path ./media\* -not -path ./plugins\* -not -path ./tmp\*"

期望的输出。

find ./ -type d -not -path ./\.git\* -not -path ./administrator/cache\* -not -path ./images\* -not -path ./logs\* -not -path ./cache\* -not -path ./media\* -not -path ./plugins\* -not -path ./tmp\*

输出损坏

find ./ -type d ${findIgnorePaths}

对于任何想要查看我的脚本的人，我正在解决上述问题，请查看以下内容：

这是Bash FAQ 50，建议您使用array variable将参数传递给程序：

findIgnorePaths=(-not -path './.git*' -not -path './administrator/cache*' -not -path './images*' -not -path './logs*' -not -path './cache*' -not -path './media*' -not -path './plugins*' -not -path './tmp*')
find ./ -type d "${findIgnorePaths[@]}"

注意目录globs是单引号，因此在创建变量时shell不会解释它们。你的反斜杠逃脱做了同样的事情;这是个人偏好的问题，你觉得哪一个更容易阅读。

通过shellcheck.net运行脚本总是一个好主意，可以找到潜在的任何问题。

另外，/bin/sh不是/bin/bash，所以修复你的shebang！
