我有一个相当大的文件系统,假设我想在文件系统的某个区域中找到包含 String 的所有文件和目录,ActionListeener为此我想使用tree. 所以如果我这样做:
tree ~/ | grep ActionListeener
Run Code Online (Sandbox Code Playgroud)
结果将是:
? ? ? ??? ActionListeener.class
? ? ??? ActionListeener.java

所以我现在知道这些文件确实存在于我的文件系统更深的某个地方,但我不知道哪个文件夹包含子文件夹,哪个文件夹包含子文件夹,等等。
所以我的问题是,我怎样才能获得树命令(通过将输出管道传输到其他东西)来显示文件夹和路径,这些文件夹和路径将我引导到包含该字符串的那些特定文件?

使用-f树的选项。从man tree:
-f 打印每个文件的完整路径前缀。
所以你的命令将是:
tree -f ~/ | grep 'ActionListeener'

请注意,这将匹配ActionListeener行中的任何位置,因此请精确选择要在哪个目录中运行它。
将tree的模式匹配 ( -P) 与 结合使用--prune:
$ tree
.
??? archlinux-simplyblack
? ??? angle-down.png
? ??? archlinux.png
# snip
??? reboot.png
??? shutdown.png
??? theme.conf
8 directories, 78 files
$ tree -P 'reboot*' --prune
.
??? maui
? ??? reboot.png
??? maui-dark
??? reboot.png
2 directories, 2 files

来自man tree:
-P pattern
List only those files that match the wild-card pattern. Note:
you must use the -a option to also consider those files
beginning 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.
--prune
Makes tree prune empty directories from the output, useful when
used in conjunction with -P or -I. See BUGS AND NOTES below for
more information on this option.
