Linux io which file

Agreed your script is a better approach, I'm still surprised that there isn't a general purpose tool that does what you ask. Seems like a big gap in Unix. Most of the help is just extremely targeted which can get a little annoying, since when answering you're saying the same thing a lot of times over and over in different ways.

But that's the nature of the SE sites. I don't know how Gilles does it. Show 3 more comments. Active Oldest Votes. So what to do? References fatrace: report system wide file access events fatrace - report system wide file access events Another new ABI for fanotify blktrace User Guide.

Improve this answer. Sweet baby Jesus, slm. You are like the rockstar of Unix SE as far as I'm concerned. You answers are always incredibly educational and show a lot of research all in one place. Most people if they knew about it would have just posted the last bit about fatrace and not developed it much passed that. I really do appreciate how you go the extra mile to make sure people understand the complete picture and wish I could do more than just upvote and give bounty.

JoelDavis - thanks for your very kind words. I liked your idea of making a canonical answer so I was attempting to start that here. I've run into this problem many times as well and wished I had a resource like this so I figured we'd create it here One thing I'm confused about: When I did the install yum pulled in python3's libraries for some reason.

I did a file on it and it looks like it's an ELF executable. Any idea why it bothered with python3? BTW, apparently I have to wait some time after accepting the answer to award bounty.

Not really an issue for me, no. I can get the information I need about that via the appropriate iotop and iostat calls. You can read more about dstat here. It does an excellent job of summarizing changes in each interval. The bottom section shows processes that did interesting things during the interval. You can read more about atop here. All the tools listed above have more features and options, here are good places to start digging further: iostat , iotop , dstat , atop and ioping.

Both are fairly complicated, but are standard tools for the job. In Linux, user programs cannot access services provided by the kernel directly, and they must use the services provided by the kernel through system calls. These system call programming interfaces are mainly implemented through the C library libc. Expiration portal: The most complete summary of Linux common commands ever super detailed!
