# rmlint > Find space waste and other broken things on your filesystem. > More information: . - Check directories for duplicated, empty and broken files: `rmlint {{path/to/directory1 path/to/directory2 ...}}` - Check for duplicates bigger than a specific size, preferably keeping files in tagged directories (after the double slash): `rmlint {{[-s|--size]}} {{1MB}} {{path/to/directory}} // {{path/to/original_directory}}` - Check for space wasters, keeping everything in the untagged directories: `rmlint {{[-k|--keep-all-untagged]}} {{path/to/directory}} // {{path/to/original_directory}}` - Delete duplicate files found by an execution of `rmlint`: `./rmlint.sh` - Find duplicate directory trees based on data, ignoring names: `rmlint {{[-D|--merge-directories]}} {{path/to/directory}}` - Mark files at lower path [d]epth as originals, on tie choose shorter [l]ength: `rmlint {{[-S|--rank-by]}} {{dl}} {{path/to/directory}}` - Find files with identical filename and contents, and link rather than delete the duplicates: `rmlint {{[-c|--config]}} sh:link {{[-b|--match-basename]}} {{path/to/directory}}` - Use `data` as master directory. Find only duplicates in backup that are also in `data`. Do not delete any files in `data`: `rmlint {{path/to/backup}} // {{path/to/data}} {{[-k|--keep-all-tagged]}} {{[-m|--must-match-tagged]}}`
