Instruments has a command line interface:
Instruments 有一个命令行界面：
$ instruments -h
Example usage:
用法示例：
$ instruments -t mytemplate -a myapp.app
For leaks, try the Leaks.tracetemplate. To see all available templates, use -s.
对于泄漏，请尝试Leaks.tracetemplate. 要查看所有可用模板，请使用-s.
There is another executable, just called leaks. You can inspect any running application by giving leaksits PID:
还有另一个可执行文件，只是称为leaks. 您可以通过提供leaks其 PID来检查任何正在运行的应用程序：
$ ps aux | grep "[b]ash" | awk '{print }'
620
$ leaks 620
leaks Report Version: 2.0
Process: bash [620]
Path: /bin/bash
Load Address: 0x100000000
...
Process 620: 37983 nodes malloced for 1123 KB
Process 620: 0 leaks for 0 total leaked bytes.
Read more about leaks in the Apple developer reference library.
在 Apple 开发人员参考库中阅读有关泄漏的更多信息。
