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