Q: How can I check if a process creating a named pipe or not at run time using activity monitor?

I have a process which at run time should create a named pipe. Some time it does not seams to create this pipe and exited. I do not have its source code hence cannot confirm by debugging it.

Does activity monitor help me to find if a process has created a named pipe or not? if so how?

 

Any help is appreciated.

 

Thanks

    A named pipe is not a process. It's an object in the file system. If you know where it's supposed to be, you can look for it in the Finder. Otherwise, you'd have to search for it in the shell by a suitable invocation of find(1).

    Thanks Linc. but if the pipe is created at runtime and then deleted by the process when process exited it is difficult to find it in finder. specially when the pipe name is random and based on process ID.

     

    Is there a tool on MAC similar to Process monitor on windows which logs all activities on a running process for further analysis.

     

    Anyways thanks a lot. :-)

    There is no easy way to do what you want. You're asking how to debug someone else's app. See the man pages for fs_usage(1) and opensnoop(1m).

    Is it listed under the main process in Activity Monitor? Get info on the process (double click it) & open files & ports should be listed.
