tree – only show files with matching file name but not directories that don’t contain the file

I want to use tree to only show files that match a specific file name. E.g. filename.

The man page says:

-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.

However, I don’t want to show  directories that don’t contain that file.

Here’s how:

tree . -P filename --prune

(if you don’t have tree then: brew install tree)

and if you want to match on directories too then use:

tree . -P *match string* --matchdirs --prune


Making this an alias:

`alias treefind=”tree . –prune –matchdirs -P”` so you can use it like this:

treefind some_file


and if you’re wanting to use a regex then:

treefind 'some_*'
