The difference between /usr/local/bin and /usr/bin

First, the difference between /usr/sbin and /usr/bin:

1. /usr/sbin: Commands under root authority are basic system commands, such as shutdown, reboot, which are used to start the system and repair the system;

2. Ordinary user authority of /usr/bin, storing some common basic commands, such as ls, chmod, etc.;

Second, /usr/bin and /usr/local/bin:

First note that usr refers to Unix System Resource, not User

Then usually:

The executable programs under /usr/bin are all pre-installed executable programs in the system, which will change with the system upgrade.

/usr/local/bin directory is a place for users to place their own executable programs. It is recommended to place them here, so that files of the same name will not be overwritten by the system upgrade.

1. /usr/bin: The executable program pre-installed in the system will change with the system upgrade;

2. /usr/local/bin: The place where users put their own executable programs, it is recommended to put them here, and the files of the same name will not be overwritten by the system upgrade.
