+
+> Breadth-first search for your files.
+> More information: <https://manned.org/bfs>.
+
+- Find files by extension:
+
+`bfs {{root_path}} -name '{{*.ext}}'`
+
+- Find files matching multiple path/name patterns:
+
+`bfs {{root_path}} -path '{{**/path/**/*.ext}}' -or -name '{{*pattern*}}'`
+
+- Find directories matching a given name, in case-insensitive mode:
+
+`bfs {{root_path}} -type d -iname '{{*lib*}}'`
+
+- Find files matching a given pattern, excluding specific paths:
+
+`bfs {{root_path}} -name '{{*.py}}' -not -path '{{*/site-packages/*}}'`
+
+- Find files matching a given size range, limiting the recursive depth to "1":
+
+`bfs {{root_path}} -maxdepth 1 -size {{+500k}} -size {{-10M}}`
+
+- Run a command for each file (use `{}` within the command to access the filename):
+
+`bfs {{root_path}} -name '{{*.ext}}' -exec {{wc -l}} {} \;`
+
+- Find all files modified today and pass the results to a single command as arguments:
+
+`bfs {{root_path}} -daystart -mtime {{-1}} -exec {{tar -cvf archive.tar}} {} \+`
+
+- Find empty files (0 byte) or directories and delete them verbosely:
+
+`bfs {{root_path}} -type {{f|d}} -empty -delete -print`
