Question

I have some scripts that ought to have stopped running but hang around forever. Is there some way I can figure out what they’re writing to STDOUT and STDERR in a readable way?

I tried, for example, to do:

$ tail -f /proc/(pid)/fd/1 

but that doesn’t really work. It was a long shot anyway.

Any other ideas?

strace on its own is quite verbose and unreadable for seeing this.

Note: I am only interested in their output, not in anything else. I’m capable of figuring out the other things on my own; this question is only focused on getting access to stdout and stderr of the running process after starting it.

I’m not sure if it will work for you, but I read a page a while back describing a method that uses gdb
