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.

What's the difference between /bin and /usr/bin and /usr/local/bin from an architectural point of view? And how does sbin relate to this?

[–] [email protected] 6 points 6 months ago (2 children)

There's a standard. /usr was often a different partition.

/bin - system binaries
/sbin - system binaries that need superuser privileges
/usr/bin - Normal binaries
/usr/sbin - normal binaries that require superuser privileges
/usr/local/bin - for executables that aren't 'packaged' - i.e., installed by you or some other program system-wide

What is a binary?

[–] [email protected] 2 points 6 months ago

Actually binaries can include non-executable files as well! Strictly speaking, a "binary" refers to pretty much any file that's not plain-text (so if you tried to open a binary in a text editor, you'd see gibberish).

Executable programs! Bin-ary instructions for the computer to perform!

Also, technically these will not just have binaries. I should have said executable, really, because scripts are there, too.
