+
+> Search a process's memory for unreferenced malloc buffers.
+> More information: <https://keith.github.io/xcode-man-pages/leaks.1.html>.
+
+- Examine a running process for leaks by its name:
+
+`leaks {{process_name}}`
+
+- Examine a running process for leaks by its PID:
+
+`leaks {{pid}}`
+
+- Launch a command and check for leaks when it exits:
+
+`leaks -atExit -- {{command}}`
+
+- Enable backtraces for each leak by setting the `MallocStackLogging` environment variable:
+
+`MallocStackLogging=YES leaks {{process_name}}`
+
+- Display results in the classic list format instead of a tree:
+
+`leaks -list {{process_name}}`
+
+- Group leaked objects by type:
+
+`leaks -groupByType {{process_name}}`
+
+- Save the memory state to a memory graph file for later analysis:
+
+`leaks {{process_name}} -outputGraph {{path/to/file.memgraph}}`
+
+- Examine a previously saved memory graph file:
+
+`leaks {{path/to/file.memgraph}}`
