Programs made Available in the /usr directory

In the linux / directory, is the /usr that directory that makes anything install accessible by all users including the core system or just the users?

It's the search path environment variable PATH that makes programs from various directories available to users. Typical PATH entries include /bin /usr/bin /sbin /usr/sbin /usr/local/bin /opt/SOMEPKG/bin /usr/games $HOME/bin and so on.

Every post above this one is, sadly, wrong.

- /usr is the primary directory for system applications
- /usr does not contain all the user-specific programs (it's neither specifically user-oriented nor specific to individual users)
- /usr contains no information about system users.
- /usr is not created by the sysadmin
- it's not recommended to change icons in /usr/share/icon rather than in a per-user configuration in a user's home directory.

Local additions to the installed programs are often put in /usr/local by the sysadmin if not preconfigured installable is available (say through apt-get or yum).

The purpose of installation in the /usr directory is for non-system applications. The location does not mean that they are accessible to anyone, only that is is not a core system application. To determine what is root only you can look in the /sbin and /usr/sbin directories.
