我们如何为`tree`命令指定多个忽略模式？

我需要打印生产系统的目录结构，我想从树中删除一些特定的目录吗？

我们如何为tree命令指定多个忽略模式？

您只需为-I命令提供所有模式，以分隔即可|。从联机帮助页：

-P pattern
      List  only  those files that match the wild-card pattern.  Note:
      you must use the -a option to also consider those  files  begin‐
      ning  with a dot `.' for matching.  Valid wildcard operators are
      `*' (any zero or more characters), `?' (any  single  character),
      `[...]'  (any single character listed between brackets (optional
      - (dash) for character  range  may  be  used:  ex:  [A-Z]),  and
      `[^...]'  (any  single character not listed in brackets) and `|'
      separates alternate patterns.

-I pattern
      Do not list those files that match the wild-card pattern.

因此，例如

tree -I 'test*|docs|bin|lib'

跳过“ docs”，“ bin”和“ lib”目录，名称中带有“ test”的任何目录，无论它们位于目录层次结构中的何处。显然，您可以应用通配符进行更强大的匹配。
