In Linux, the command to execute the directory (that is, the directory where the executable file is stored) is /usr/bin. This directory contains most of the executable files in the system, which can be executed directly through the command name.
When you enter a command in the terminal, Linux will search the execution directory in a certain order to find the executable file of the command. Usually, the /usr/bin directory is included in the system environment variable $PATH, so you can directly execute commands in this directory in the terminal.
Note that the execute directory can contain other subdirectories for organizing different types of executables. For example, there may be subdirectories such as /usr/bin/sbin and /usr/bin/local under /usr/bin, which are used to store specific types of executable files.
In addition to the /usr/bin directory, there are other common execution directories, such as /bin, /sbin, /usr/sbin, etc. Each directory has its specific purpose and scope. Which directory to use depends on your system configuration and needs.
