Question

Is there a way to find what path a command has had it’s output redirected to (if it has been)?

I tried using:

ps -p PID -o cmd

Thinking I could look for a > and extract the path from that, but the output doesn’t have that part in it. I’m pretty sure it hasn’t just been truncated.

You can use the proc file system /proc/self/fd for this

readlink /proc/self/fd/1

for stdout or 2 for stderr.
