ltrace equivalent for osx?
提问by Enki
osx has the really powerful dtrace/ktrace/dtruss tools - however i'm not willing to invest the time necessary to learn dealing with them right now.
osx 拥有非常强大的 dtrace/ktrace/dtruss 工具 - 但是我现在不愿意投入必要的时间来学习处理它们。
what's the easiest way to get the equivalent functionality of linux ltrace (and possibly strace) on OSX?
在 OSX 上获得 linux ltrace（可能还有 strace）的等效功能的最简单方法是什么？
回答by Dean Povey
No answer for ltrace (except perhaps "work out how to use dtrace" :-) ), but for system call tracing ala strace, dtruss is a pretty good front end to dtrace.
ltrace 没有答案（除了“弄清楚如何使用 dtrace”:-)），但是对于系统调用跟踪 ala strace，dtruss 是 dtrace 的一个很好的前端。
e.g.
例如
dtruss df -h # run and examine the "df -h" command
dtruss -p 1871 # examine PID 1871
dtruss -n tar # examine all processes called "tar"

you don't need to learn dtrace to use it. there are quite a few dtrace scripts that come with OSX. To see an (incomplete) list:
您无需学习 dtrace 即可使用它。OSX 附带了很多 dtrace 脚本。查看（不完整的）列表：
man -k dtrace
man -k dtrace
In your case dapptracemight do the job.
在你的情况下dapptrace可能会完成这项工作。

I'd suggest that DTrace is not as complex as you think it is. I just wrote a two-part tutorial on using DTrace to tune Cocoa applications for the Mac or iPhone, which can be found hereand here. I came into it thinking that DTrace would be extremely difficult to work with, but it turns out to be reasonably straightforward to use.
我建议 DTrace 并不像您想象的那么复杂。我刚刚写了一篇关于使用 DTrace 为 Mac 或 iPhone 调整 Cocoa 应用程序的两部分教程，可在此处和此处找到。我开始认为 DTrace 很难使用，但结果证明它使用起来相当简单。
