How to use ag aka the_silver_search to search for directories only?

Question

I like to search for directories only, and the option ag --list-file-types is not helpful with that. The reason to stick to ag is the possibility to pick a file with --path-to-ignore containing patterns to ignore.

An equivalent command would be fd --type d.

Answer 1

Use the -G argument, and specify a directory name.

For example, if you wanted to search for the word "foobar" in only your Downloads directory:

ag -G "Downloads" foobar

To search inside a nested directory:

ag -G "Downloads/some_directory" foobar 

To search in multiple directories:

ag -G "Downloads|Documents" foobar
