tree: ignore directories with patterns


tree displays the directory structure of the current directory. -d option displays only directories. -I option allows to exclude directories that match specific pattern e.g.

tree -I node_modules

In order to exclude multiple directories at once, their names must be separated by | sign, i.e.

tree -I 'node_modules|cache|test_*'

This command will skip node_modules, cache directories (along with their content) from the output, and all directories that match test_* wildcard expression.
