I am using tree to list contents of a folder. I have many macOS apps with .app extension. I want tree to list them but ignore the contents inside it. How to do that? Thanks.

  • tree is a plain POSIX command so does not know about macOS bundles. You'll need a macOS specific tool.

tree has -P and -I to show/hide files based on wild-card patterns but I didn't have any luck so far using them to hide the content of specific directories.

You can remove the content of NAME.app directories with grep though:

tree -f | grep -v '\.app/'

-f is required in this case to allow filtering on the whole path.

If you don't want to see the whole path, you can also remove it again with sed:

tree -f | grep -v '\.app/' | sed 's| \./.*/||'

The resulting output is similar to the one you get without -f, but without the content of the .app directories.

  • Thanks. Works. But I don't want the full path prefix for each file listed. I guess I will just remove the app content entries manually.

  • @JohnDoe Found a way to remove the path after the filtering. Not sure it covers all edge cases.
