FAQ
Hi Philip,

Thanks I understand the working directory of the process.

-Dhanasekaran.

Did I learn something today? If not, I wasted it.

Hi Dhanasekaran,

The easiest way to find the working directory of a process is to "ls -ld
/proc/18241/cwd". See 'man 5 proc' for more details (search for "cwd").

I apologize for the docs you found not being clear about how to find the
process number.

Hope this helps,

-- Philip
