From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Anyone know how to see what pid/process has modified a linux routing table (specifically on Ubuntu )? I have an interesting problem where a route that I have created has been deleted over time, but can't figure out what. I've tried rtmon but seems to only show timestamps of the adds/deletes

My bad, I thought in Linux everything is a file

Well, the routes might manifest somewhere as files, but I don't expect anyone to be able to viably parse them without commands like ip or ifconfig (or know where the files even are).

Some devices (like disks for example) are very straightforward to use as files, while some other special files (like USB devices) are so weird/ugly to use that everyone uses tools/libraries to access them (like libusb).

This is very off-topic, but there's a great talk by Benno Rice that talks about this (among many others): https://youtu.be/9-IWMbJXoLM
