In all current Linux I know of right now...
man hier That will give you the run down of everything. Including /opt and the reasoning for it.
From that:
/opt This directory should contain add-on packages that contain static files.

/opt was BS prop sheeite from the get go
brought in by sun to differentiate
/var bullshit
/opt bullshit
a real OS had
/bin for binaries
/etc for config files
/dev for drivers and devoces
/tmp for swap
/usr for anything a user might need or want that wasnt supplied by the OS vendor
marketing crapaud all of it

BS...
/usr used to be for the *user's* home directories and was actually /u/<username>
When everyone started to use things (programs, scripts and such) out of everyone else's homedir... things changed and it became what it is today (a huge mess).
I was working on a very old HP 900 series machine... (the initial series they bought Apollo for). All the home dirs for the machine were /u/(8char username)
The damned thing booted off tape every time. The disks were not bootable. Though it had a CDROM it was 1X "HP-IB" SCSI and would only read it as a tape device only.
/u became popular again as a replacement for /usr, because many admins and companies wanted to make /usr static/read-only. /home now supersedes /u for the user's homedirs, for obvious reasons.

wrong /u/ was homedir /usr appdir

sorry box
/usr/bin had a SHITLOAD of stuff that came with my default install.
/bin had the limited amount of stuff needed when booted single user for maintainance, but certainly not 90% of the system supplied text processing apps, or the compilers, or the nroff/troff stuff, or the (you get the point) (I hope).
My stuff was late 70s early 80s gear. I was paying close attention to the Sys V/BSD differences since I had to port my code between them, and the bastardized Xenix systems.

why sorry you are agreeing with me :-)

Definition problem
I listed tools, not applications.
But I see what you mean.
Once the system is booted, your job is done.

say: /usr
Go on... say it.
What does that sound like?
/u was used for a "short" user.
Then as slightly more memory became available, it was expanded to /usr.
Initially /usr/<username>/program was being used heavily by many people and then as the idea of $PATH came into being... a blessed path was written in. This is where /usr/bin came from. to distinguish from /usr/<username>. Then a lot of people started griping that some systems things to boot where being written and put in /usr/bin.
Eventually /bin and /sbin became the places for system starting programs and other initialization programs need to boot the machine were.
So early crap was /u for homedirs. /u being cryptic, became less so with a pronounceable version "/usr" or user. Then when these things became where admins (out of being lazy and not want to compile/link everything on install) wanted to make /usr *read-only* and exportable and mounted from a central machine. /u became the user directory again and eventually /home.
Sorry, you mind is playing tricks on you again. I've referenced some mimeo-graphed training manuals I have from 1984 that were given to me with that OLD 900 series machine. they intermixed /u and /usr because at that point /u was considered legacy.

fair enough
maybe my memory isnt what it used to be. I have the first edition ATT unix prog manual written by Kernihan and Ritchie. I will take a look when I get home to see If there is any references one way or the other.
