In Linux, I can check the max allowed open files (ulimit) of a process by simply executing
$ cat /proc/<PID>/limits Limit Soft Limit Hard Limit Units Max cpu time unlimited unlimited seconds Max file size unlimited unlimited bytes Max data size unlimited unlimited bytes Max stack size 8388608 unlimited bytes Max core file size 0 unlimited bytes Max resident set unlimited unlimited bytes Max processes 14248 14248 processes Max open files 1024 1048576 files Max locked memory 67108864 67108864 bytes Max address space unlimited unlimited bytes Max file locks unlimited unlimited locks Max pending signals 14248 14248 signals Max msgqueue size 819200 819200 bytes Max nice priority 0 0 Max realtime priority 0 0 Max realtime timeout unlimited unlimited us
How can I do this in MacOS?
Thanks a lot.
PS1: I knew how to run
ulimit commands to check the current ulimit setup. But I don't know how to check and verify those values for a running process.
PS2: I knew how to use
lsof to check how many files a process is opening. But it doesn't tell the max number of files a process can open.
