巴什发现-print裁剪结果？

Question

编辑：我缩小了问题的范围，并更改了标题以反映这一点。

我很难理解为什么find的-print会删除一些结果。

在未打印的示例中，它将按预期显示。当我们添加-print选项时，它会删除许多结果。在本例中，它所切割的结果似乎是build文件夹中的任何内容，也是src中的任何内容。

无print的

$ find . -type f -name "*.rs" -or -name "*.dylib"

Answer 1

找到问题了！

原来这是个范围问题。

find . -type f -name "*.rs" -or -name "*.dylib"

评估为

find . \( -type f -name "*.rs" -or -name "*.dylib" \) -print

鉴于

find . -type f -name "*.rs" -or -name "*.dylib" -print

评估为

find . \( -type f -name "*.rs" \) -or  \( -name "*.dylib" -print \)

因此，-type f -name "*.rs"没有与之相关的操作，也从未被打印出来。

如果我理解得不对，请告诉我。
